3 MATERIAL NEEDED FOR THE INSTALLATION
3.1 CONTENTS OF THE XCOM-CAN MULTI-PROTOCOL COMMUNICATION SET
The multi-protocol communication set Xcom-CAN contains the following material: One Xcom-CAN module
Two 2 meters communication cables, to connect the Xcom-CAN to Studer and external devices Mounting plate
2 DIN ريل ڪلپس ۽ پيچ
3.2 OTHER REQUIRED MATERIAL
In addition to the material delivered with the communication set the use of an Xcom-CAN necessitates a cross-headed screwdriver #1 (P1). Since the Xcom-CAN is dedicated to communicate with a third-party system (Battery, SCADA, PLC etc.) you will need a specific cable crafted with the proper connector and pinning on each side. See chapter 0.
This device should not be used for any purpose not described in this manual. The device is using RJ45 connectors frequently used and standard for LAN (Local Area Network). The Xcom-CAN should never be used or plugged into communication networks other than the ones specified in this manual. This will seriously damage the product.

4 FUNCTIONALITIES OF THE XCOM-CAN
There are several functionalities (applications) listed below that can be achieved with the Xcom-CAN module. These functionalities (applications) can be selected by the proper setting of the DIP switches located inside the module. See chap. 5.1.
4.1 CONNECTION OF AN XTENDER-VARIO SYSTEM TO LITHIUM BATTERIES
An optimal management of Lithium batteries requires communication between the battery and the whole system, like inverters, chargers, display, SCADA and so on. Most Lithium batteries use a CAN bus (as physical layer) but must have specific protocols implemented to communicate. The Xcom-CAN has several protocols implemented for battery management. These protocols are compatible with specific batteries, as listed in chap. 5.2.
4.2 ACCESS/CONTROL OF STUDER DEVICES FROM A THIRD-PARTY SYSTEM (PLC, SCADA)
The Xcom-CAN can be used to interface a Studer Xtender/Vario system with a third-party device via a CAN communication bus (SCADA system, PLC, etc.) with the Studer Public protocol. The technical specification of this protocol is available on Studer’s web site, www.studer-innotec.com, and will allow the third-party device to read and write data, get alarm or messages and fully control the Xtender/Vario system.
5 INSTALLATION OF THE XCOM-CAN
This device was designed for indoor use only and must under no circumstances be exposed to rain, snow or any other humid or dusty environment. As far as possible, reduce exposure to sudden temperature variation: important heat variation may create undesired and harmful condensation inside the equipment. Before installing the module, the configuration of the function and the selection of pin out connection must be achieved.
5.1 SELECTION OF FUNCTIONALITY AND PINOUT ARRANGEMENT
To access the DIP switches and jumper array, the module must be opened. First disconnect your Xcom-CAN module from all devices (installation, battery, etc.) then open the Xcom-CAN with a Phillips screwdriver #1 (2 screws). On the electronic board inside the device there are two elements to select the chosen configuration:
(1) Jumper array for RJ-45 (third party side) pinout arrangement. (2) DIP switches to select the protocol/battery model (switch 1 to 5) and the bus speed (switch
6 to 8) whenever the protocol requires it.

5.2 DIP SWITCH CONFIGURATION FOR LITHIUM BATTERIES
Note: The list of compatibility is subject to change. Please contact Studer Innotec to get the updated list.
The information on the configuration of the DIP switches for lithium batteries can be found at https://support.studer-innotec.com/battery-compatibility

Note: This table is for “Activity Control” mode. For “Activity Inspect” mode, switch 4 must be in “ON” position. For more information about activity modes, please refer to chapter 6.
* Please check details with the battery manufacturer for warranty conditions and availability **UP2500NB01V00101 released April 2020 has the CANBUS port and is supported.
All the listed batteries are compatible with the Xcom-CAN in terms of protocol. Studer Innotec is not responsible for performance and compliance to system size and requirements. When working with Lithium batteries, the Xcom-CAN will automatically change the Xtender system parameters related to the battery management (Xtender, VarioTrack & VarioString).
5.3 DIP SWITCH CONFIGURATION FOR THIRD PARTY PLC OR SCADA SYSTEMS
To interact with the Xtender/Vario systems through third party devices such as PLC or SCADA, you have to select the “Studer Public protocol”. The “Studer Public Protocol” is available in two operating modes and with different CAN bus speed options. These can be set up in different combinations depending on the user’s needs.
5.3.1 “Exclusive Protocol” operating mode
This configuration is recommended when there is only one device communicating with the “Studer Public Protocol” on the external CAN interface. The Xcom-CAN will send a response to every frame that appears on the external CAN interface. For frames which do not fit the “Studer Public Protocol” specifications, the Xcom-CAN will send an error frame message. This mode is practical for debugging as every frame sent by the PLC/SCADA will get a response. It will also detect any frame that could be corrupted when transmission occurs.
Configuration of DIP switches in “Exclusive Protocol” operating mode at 250 kbps. CAN speed can be adjusted depending on your needs, see chapter 0.

V2.9.1

استعمال ڪندڙ دستي

Studer Innotec SA Xcom-CAN
5.3.2 “Tolerant Protocol” operating mode
This configuration is recommended when there are several devices communicating with different protocols on the external CAN interface. The Xcom-CAN will only send a response to the frames that completey fit the “Studer Public Protocol” specifications. This mode enable the installer to extend the CAN bus on the external interface and to add others devices that can communicate with the PLC/SCADA on the same physical support as the Xcom-CAN.
Configuration of DIP switches in “Tolerant Protocol” operating mode at 250 kbps. CAN speed can be adjusted depending on your needs, see chapter 0.

Sharing the Xcom-CAN’s external CAN interface with other devices and protocols is possible but needs special attention. A frame conflict can occur. It is the responsibility of the installer/developer to make sure that frame conflicts between two or more devices/protocols are avoided.

5.4 CAN BUS SPEED
The Studer public protocol and some batteries allow different CAN bus speed. This choice must be done in accordance with the third party device speed. Select the communication speed with the DIP switches in position 6 to 8 according to the table below. The default setting is 250kbps.

5.5 CABLE BETWEEN XCOM-CAN AND THIRD PARTY DEVICE OR BATTERY
Most communication devices provide a specific connector and pin assignment. A specific cable having on one side an RJ-45 connector and on the other side the third-party devices connector is required. This cable is either supplied by the manufacturer or must be crafted by the installer. The Xcom-CAN package provides 2 cables with RJ-45 connectors on both ends. One of the two can be used to craft the proper cable.
5.6 SELECTION OF THE PIN ASSIGNMENT OF THE CAN BUS CONNECTION
Any communication signal can be assigned to any pin of the RJ-45 connector by using the jumper array (1) in Figure 1.

5.8 CONNECTION OF THE COMMUNICATION BUS (STUDER SIDE)
The Studer bus is daisy chained to the other XT/VT/VS Studer components and is powered by the communication plug as soon as the upfront device is powered. The Xcom-CAN module should not be installed between 2 devices powered by the battery. Connect the Xcom-CAN module with the supplied cable (2m). This cable should not be extended.
Do not connect the Xcom-CAN between devices connected to the battery. Do not connect the module to a device not connected to the battery (RCC or other Xcom).
The termination switch of the communication bus “Com. Bus” remains in position T (terminated) except when both connectors are used. In this case and only in this case, the switch must be placed in the O (open) position. If one of the two connectors is not used, the termination switch will be in position T. An incorrect setting of the link ends can lead to an erratic running of the system or impede its updating process.
By default, the termination is set to terminated (position T) on each Studer product.

Figure 2: Connection schematic for Xcom-CAN
5.9 CONNECTION OF THIRD-PARTY DEVICES
In most cases, a specific cable must be crafted by the installer according to chapter 5.6 . This cable will have on the Battery BMS side the appropriate connector supplied or recommended by the third-party device manufacturer (Battery, SCADA, PLC etc.) and on the Xcom-CAN side an RJ-45 connector.

6 USING XCOM-CAN WITH LITHIUM BATTERIES
The use of lithium batteries requires special care. It is the responsibility of the installer to handle the battery correctly and to conform to the safety requirements of the battery manufacturer. Studer Innotec will not be responsible for any damage done to the battery and/or to the installation in case of wrong/bad handling of the lithium battery.

The use of an Xcom-CAN with lithium batteries is incompatible with the use of a BSP. Therefore, it is not possible to have an Xcom-CAN working in BMS mode together with a BSP on the same Studer CAN bus.

The Xcom-CAN module supports lithium batteries with BMS communicating on the CAN bus. See chapter 5.2 for a complete list of compatible brands. The Xcom-CAN should not be used with lithium batteries that are not on this list.
The Xcom-CAN module enables the use of lithium batteries with your Xtender/Vario installation. Lithium batteries are more complicated to handle compared to simple lead acid batteries. Lithium batteries usually embed a BMS (Battery Monitoring System) which is responsible of cell monitoring and battery safety. The BMS knows the status of each cell, and it computes maximum charging/discharging currents and maximum/minimum target voltages. These values, that change dynamically, are known as set points/limits and must be respected when the installation is working. When using the Xcom-CAN module with compatible lithium batteries, the installer, depending on the application, can choose between two operating modes:
· “Activity Control” operating mode · “Activity Inspect” operating mode
6.1 “ACTIVITY CONTROL” OPERATING MODE
In this operating mode (which is the most commonly used), the Xcom-CAN module enables automatic use of compatible batteries within an Xtender/Vario system. Thanks to the communication protocol between the battery’s BMS and the Xcom-CAN, the system is plug and play. The user no longer have to care about the battery’s configuration. For this reason, the battery configuration menus for the Xtender, VarioTrack and VarioString are removed from the RCC when using Xcom-CAN with a compatible battery in “Activity Control” operating mode.
At start-up, the Xcom-CAN automatically configures the system based on information received from the battery’s BMS. Once the installation is running, the Xcom-CAN takes into account the set points/limits sent by the battery’s BMS and manages the connected Xtenders, VarioTracks and VarioStrings accordingly.
For safety reasons, the battery’s BMS can send warnings/alarms via the communication protocol. The Xcom-CAN module reacts to these as soon as possible and tries to solve the problem by automatically stopping the charge and/or discharge of the battery, depending on the nature of the warning/alarm. A typical example would be an overvoltage warning/alarm. The Xcom-CAN will react by stopping the charge of the battery.
The reaction of Xcom-CAN on warnings/alarms is normally fast enough to avoid the battery’s BMS to disconnect the battery from the installation by opening its relays. However, this situation might occur in exceptional situations (e.g. battery internal damage). In any case, the safety of the battery is guaranteed by the battery’s BMS, not by the Xcom-CAN module.
In “Activity Control” operating mode, a third-party controller (e.g. SCADA, PLC) might be used (typically as a supervision functionality) but is not mandatory. Several applications are fully plug and play and do not need an additional controller (refer to chapter 0 for a list of plug and play applications).

استعمال ڪندڙ دستي

V2.9.1

Studer Innotec SA Xcom-CAN

6.2 “ACTIVITY INSPECT” OPERATING MODE

In this operating mode, the Xcom-CAN module acts as an interface between the battery’s BMS and a third-party system (e.g. SCADA, PLC). The Xcom-CAN module decodes the communication protocol and makes the information available. The third-party controller will access this information by reading the different Xcom-CAN User Information (see chapter 6.6.3 for a complete list). This can be done by using an additional Xcom-232i module with the SCOM protocol or by using a second Xcom-CAN module configured in “Studer public protocol” mode (see chapter 4.2). The third-party controller will need to control all Studer Innotec devices on the installation and ensure that set points/limits sent by the battery’s BMS are respected. The third-party controller will be responsible for the safety of the complete installation. The Xcom-CAN will not perform any action on the installation.

6.3 SELECTING OPERATING MODE

Selecting operating mode is done by DIP switch 4 regardless of the battery model. The table in paragraph 5.2 shows the DIP switch configuration for the compatible battery in “Activity Control” mode. For “Activity Inspect” mode, it is the same, except that the switch 4 must be to “ON”. To summarise:
· “Activity Control” operating mode : DIP switch 4 must be in position “OFF” · “Activity Inspect” operating mode : DIP switch 4 must be in position “ON”

6.4 BATTERY POWER UP

Follow the battery manufacturer start-up procedure. Some batteries have a preload system unable to pre-charge all the devices connected to the battery. In this case, disconnect all devices connected to the battery. Repeat the start-up procedure and after a few seconds, reconnect the devices. You can achieve this by using additional breakers on the battery cables.

6.5 SYSTEM POWER UP

Once the Xcom-CAN is connected and powered by the Studer system it will perform different sequences indicated by the bi-coloured LED (b) according to chapter 5.10.1.

6.6 BATTERY MONITORING ON THE RCC

If an RCC is present in the system, several information is available in a specific screen dedicated to the battery.

6.6.1 Displayed values

In area (A), the Xcom-CAN displays four values. The

information to be displayed can be selected with the

key “SET” and arrow up/down to select the field, and

6.7.1 Restore default settings {6004}
Use this parameter to restore the initial settings of the Xcom-CAN.
If your installer has made some settings at “installer” level while commissioning your installation, this function restores his settings and not the factory ones.
6.7.2 Restore factory settings {6005}
With this function, you will restore the factory settings. For each parameter, not only the factory value is restored but also the limits and the user level. This function is only accessible with the level “installer”.
6.7.3 SOC level under which battery discharge is stopped {6070}
You can find this parameter in the “Advanced settings menu” of the Xcom-CAN. This parameter defines a SOC level under which battery discharge is stopped to prevent any battery dammage caused by deep discharge. The Xcom-CAN will automatically disable all Xtender functionalities that discharge the battery when the actual value of the SOC is lower than this paramenter. For example, if you set this parameter to 4%, the battery discharge will stop once the SOC value reach 3 %. It will only be possible to discharge the battery again once the SOC level reach 5% (except from the system’s self-consumption). If you set this parameter to 0%, it will not be taken into consideration. In this case the discharge of the battery will be stopped by the communication between the BMS and the Xcom-CAN or by an undervoltage detected on one Studer Innotec’s devices.
6.7.4 SOC for backup {6062}
You can find this parameter in the “Advanced settings menu” of the Xcom-CAN.

V2.9.1

استعمال ڪندڙ دستي

Studer Innotec SA Xcom-CAN
This parameter defines a SOC value that will be maintained by the Xtender/Vario system. This SOC level is your energy reserve in case of blackout (grid failure or grid disconnection). Energy to maintain this level of SOC is taken in priority from the VarioTrack and/or VarioString. If there is not enough energy available from DC-coupled devices, energy is taken from the grid through the AC-In of the Xtender. Once this set level of SOC is reached, no more energy from AC-In will be used.
6.7.5 SOC for grid feeding {6063}
You can find this parameter in the “Advanced settings menu” of the Xcom-CAN. This parameter defines a SOC value from which the system starts to feed the grid, in case grid feeding is enabled. If energy is available from DC-coupled devices when the SOC reaches this parameter value, the system will feed the exra amount of energy from the VarioTrack/VarioSting to the grid.
6.7.6 SOC for end of charge {6075}
You can find this parameter in the “Advanced settings menu” of the Xcom-CAN. This parameter defines a SOC value that will limit the maximum charge level. All chargers (inverters and solar chargers) stop and the battery never exceed this SOC. By setting this parameter under 100% can be benefical for the battery lifetime. Warning! Some SOC calculation algorithm may have troubles if the SOC does not go up to 100% for recalibration. Ask the battery manufacturer. In case of doubt set 100% to this parameter {6075}.

6.7.7 Charge current limit ratio {6078}
You can find this parameter in the “Advanced settings menu” of the Xcom-CAN. The max charge current is given by the BMS of the battery. In practice, the different BMS manufacturer have different point of view about this current. For some, it is a max charge current never to be exceeded else the battery gets faulty. For some other, it is a recommended max charge current and are tolerant if not exactly respected during transitions. So generally, the setpoint cannot be exactly on the limit.
To avoid problems, a margin of 20% was set previously (<R682) with a fixed value. This value can be chosen now with this parameter that is at 80% by default.
Note for BYD: You can set this parameter to 95% for BYD batteries to retrieve the previous behaviour. There has always been a special case for BYD batteries to allow to go at 95% of the max current. This has been asked and validated by the manufacturer.
6.7.8 Discharge current limit ratio {6093}
You can find this parameter in the “Advanced settings menu” of the Xcom-CAN. The max discharge current is given by the BMS of the battery. This parameter has the same behaviour as {6078} but for the discharging current. The default value is set to 95%.
6.7.9 Periodical full charge {6079}, {6080}, {6081}, {6104}
You can find these parameters in the “Advanced settings menu Charge/discharge settings” of the Xcom-CAN. The parameter {6079} selects the periodical full charge feature. This has been added to periodically reach a state of charge of {6104} Soc in percent to reset periodical full charge (100% by default) which is mostly used by the batteries to recalibrate their algorithm. Two parameters are used to set the interval of the full charge:
– {6080} Waiting time between periodical full charge. The interval time between two attempts of full charge. When the time elapsed, both SoC for grid-feeding {6063} and SoC for end of charge {6075} are forced to 100%.
– {6081} Time fully charged before resetting periodical full charge. When the full charge is forced and reached, this parameter allows to set the duration over which the SoC must stay to 100%. This duration must be long enough to allow the battery performing a selfcalibration. After this time, the SoC for grid-feeding {6063} and SoC for end of charge {6075} are reset to their default values.

Understanding SOC parameters {6062} and {6063}

Parameters {6062} and {6063} enable you to configure the behaviour of your installation depending on SOC.

The two parameters are dependent on each other. It is not possible to set SOC for backup {6062} at a higher value than SOC for grid feeding {6063}. In the same way, SOC for grid feeding {6063} cannot be set at a lower value than SOC for backup {6062}.

The following two figures shows a typical application using Xtender with VarioTrack and/or VarioString and how the system works depending on SOC.

خلاصو:

SOC level conditions {6075} “Max SOC for end of charge” to 100% {6063} “SOC for grid-feeding” to {6075} “Max SOC for end of charge” {6062} “SOC for backup” to {6063} “SOC for grid-feeding”
{6070} “SOC level under which battery discharge is stopped” to {6062} “SOC for backup”
0% to {6070} “SOC level under which battery discharge is stopped”

Behaviour All chargers (inverters and solar chargers) stop at this maximal level and the battery never exceed this level Energy from the VarioTrack and/or VarioString is used to feed the grid, if grid-feeding is enabled. Energy to charge the battery is taken from VarioTrack and/or VarioString. If parameter {6071} is set to “yes”, the battery priority is automatically turned on (parameter {1296} of Xtender is activated by Xcom-CAN internally) and the loads are mainly powered with battery energy. If parameter {6071} is set to “no”, no energy is taken from the battery except when the Xtender is working in “Smart-Boost” {1126}.
Energy to charge the battery is in priority taken from VarioTrack and/or VarioString. If there is not enough solar power, additional energy is used from the Xtender’s AC-In. All functionnalities that make the inverter discharge the battery are automativally turned off. It is only possible to charge the battery.

6.7.11 {6071}

Battery priority as energy source when SOC SOC for backup

You can find this parameter in the “Advanced settings menu” of the Xcom-CAN. This parameter activates the battery priority when SOC is greater than or equal to “SOC for backup” {6062}. This parameter is set to “yes” by default. The battery priority allows the Xtender to use energy from the battery in priority even if a source
(grid or genset) is connected to its AC-In port.

6.7.12

Use battery current limits instead of recommended values {6064}

You can find this parameter in the “Advanced settings menu” of the Xcom-CAN. Some battery models (e.g. IPS liCube modular LiFePO4-System) send both “reccomended values” and “limit values” on the communication interface for the charging and discharging currents. This parameter enables you to choose the values you prefer. “Recommended values” ensure long life time of the battery system by charging the battery at a lower C-rate. It is selected by setting this
parameter {6064} to “No”. “Limit values” enable you to use your battery system at the maximum possible performance (higher C-rate). It is selected by setting this parameter {6064} to “Yes”.

6.7.13

Allow user to define the maximum charge current of the battery

{6068} & Maximum charge current defined by user {6069}

You can find this parameter in the “Advanced settings menu” of the Xcom-CAN. The installer/user can define its own battery charge current limit using two parameters. Parameter {6068} enables the use of the functionnality. Parameter {6069} allows the user to define the value of the maximum charging current. Note that this value is a limit and a setpoint. It is possible that the Xcom-CAN can not reach this value if there is not enough energy or if the battery’s BMS sends a current charging limit lower than parameter {6069}. The Xcom-CAN uses the lowest value of parameter {6069} and the value sent by the BMS to control the charging current in order to respect the battery limits and to maintain the battery safety.

Allow user to define the maximum discharge current of the

battery {6076} & Maximum discharge current defined by user {6077}

You can find this parameter in the “Advanced settings menu” of the Xcom-CAN. The installer/user can define its own battery discharge current limit using two parameters. Parameter {6076} enables the use of the functionality. Parameter {6077} allows the user to define the value of the maximum discharging current. Note that this value is a limit and a setpoint. It is possible that the Xcom-CAN cannot reach this value if the battery’s BMS sends a current discharging limit lower than parameter {6077}. The Xcom-CAN uses the lowest value of parameter {6077} and the value sent by the BMS to control the discharging current in order to respect the battery limits and to maintain the battery safety.

6.7.15

Solar Inverter connected on AC-Out {6072} & Delta from user

frequency {6073} and {6074} & Ac-coupling priority {6086}

To enable control of a solar inverter connected on AC-Out with frequency shifting by the Xtender in off-grid mode, parameter {6072} must be set to “Yes”. This gives access to two sub-parameters:
– the first {6073} defines the frequency delta from the user frequency (e.g. 50Hz) at which the power derating of the solar inverter begins,
– the second {6074} defines the frequency delta from the user frequency at which the power derating of the solar inverter reach 100%.
The frequency shifting is performed according to the maximum charging current allowed by the Lithium battery.

Figure 7: Offgrid topology with solar inverter on AC-Out & derating graph according to default values of parameters {6073} and {6074}
{6073} has a default value of 1.0 Hz, which makes the frequency to start derating equals to 51 Hz. {6074} has a default value of 2.7 Hz, which makes the frequency to reach 100% derating equals to 52.7 Hz. These 2 parameters apply the same way when the frequency of the system is set to 60 Hz, which will produce 61 Hz and 62.7 Hz.
A third parameter {6086} allows to prioritize the ac-coupling solar inverter instead of the solar charger (off-grid mode only). When the ac-coupling solar inverter produces enough energy to reach the battery required charging current, the solar chargers stop producing and only the accoupling solar inverter is regulated using the frequency.

Control the derating at end of charge using {6087} and {6088}

Depending on the battery, the behavior at end of charge is different. Some of them didn’t perform a derating at end of charge in order to reduce the softly the current.

The parameter {6087} soc level to start end of charge derating and {6088} charge current rate at end of charge allows the user to control the derating. {6087} determines at which state of charge the derating starts and {6088} determines the percent of the max charging current at 100%.

Note that the battery remains the master to determine the max. charging current and the system will follow the min. value between the calculated derating and the charging current send from the battery.

6.7.17

Adaptative SoC for backup {6089}, {6090}, {6091}, {6092}

To enable the adaptative SoC for backup, the parameter {6089} must be set to “Yes”. The adaptative SoC for backup allows to force recharging the battery every seven days. Most of the batteries reset their SoC algorithm at 100%. By combining this functionality with the periodical full charge, it’s possible to force recharging the battery even without solar power.

Based on the “SoC for backup” {6062}, the adaptative SoC for backup will be increased every day from 5% until the “SoC to increase adaptative SoC for backup” {6091}. This SoC can only be reached using solar energy (no recharge from grid). When the “SoC to reset adaptative SoC for backup” {6092} is reached during more than “Time before resetting adaptative SoC for backup” {6090}, the adaptative SoC for backup is reset to the “SoC for backup” {6062}.

6.8 TYPICAL APPLICATIONS IN “ACTIVITY CONTROL” OPERATING MODE
The most typical applications in “Activity Control” operating mode are presented here. These applications are typical and variations can be made, depending on the special needs of the installation.
If you use the “Activity Control” operating mode with more than one Xtender in parallel per phase, the parameter {6071} “Use battery priority as energy source when SOC >= SOC for backup” should be set to “No” for stability reason.
In this case, self-consumption strategy can be configured by using the Grid as generator function. More details you will find in our FAQ “How should I configure the system for maximizing the self-consumption'”
6.8.1 Backup/mobile application with or without VarioTrack/VarioString
In a backup/mobile application, the user would like to have the battery fully charged in order to have maximum energy in case of blackout (backup solution) or grid disconnexion (mobile application). For such an installation, set the parameters as explained below :
1. Xcom-CAN settings : · SOC for grid feeding {6063} => 100% · SOC for backup {6062} => 100%
2. Xtender settings : · Grid feeding allowed {1127} => no · Charger allowed {1125} => yes · Inverter allowed {1124} => yes · Smart-boost allowed {1126} => yes · Maximum current of AC source (input limit) {1107} => set to the value corresponding to the fuse of your installation.
6.8.2 DC-coupled self consumption application with VarioTrack/VarioString
In a DC-coupled self-consumption application, the user would like to set a minimum SOC level for backup in case of blackout. Above this SOC level, the battery has to be charged by DC-coupled devices (VarioTrack and/or VarioString). When the SOC is really high , grid feeding can start if allowerd. An example of settings is explained below :
1. Xcom-CAN settings : · SOC for grid feeding {6063} => 90% · SOC for backup {6062} => 10%
2. Xtender settings : · Grid feeding allowed {1127} => yes · Charger allowed {1125} => yes · Inverter allowed {1124} => yes · Smart-boost allowed {1126} => yes · Maximum current of AC source (input limit) {1107} => set to the value corresponding to the fuse of your installation.

6.8.3 Manufacturer SOC for 0 % displayed {6066} and Manufacturer SOC for 100 % displayed {6067}
It is possible to scale the manufacturer SOC in order to define a user SOC. This is possible by setting the “Manufacturer SOC for 0% displayed” {6066} and the “Manufacturer SOC for 100% displayed” {6067}. It will enable the installer to define a reduced range of battery capacity whenever it is needed.

هڪ سابق جي طور تيample, imagine an installation where you want the generator to start when SOC reaches 0%. However, in order to have extra capacity in case the generator does not start you set the “Manufacturer SOC for 0% displayed” {6066} to 30%. This way you will have 30% of battery capacity as “extra reserve” in case the generator has a problem.

6.8.4 Xtender/Vario system settings

The Xcom-CAN will automatically initialize the DC voltage/current parameter of your system. All other parameters, non-related to battery management and/or specific to the installation, must be set as described in the user manual of the various XT-VT-VS appliances in the system. For example: the input limit of the Xtender {1107}, the AC output voltage {1286} or the behaviour of the auxiliary relays.

8 SOFTWARE UPDATES
In case of requirement of software upgrade of the system through the RCC unit, the Xcom-CAN is automatically upgraded. The software updates are available in the download area of the website www.studer-innotec.com/en/downloads/.
8.1 UPDATING PROCESS
Turn off all inverter units before making the update. If not manually done, the updating process will automatically stop all Xtender connected to the communication bus.
To carry out an update, insert the micro SD card (containing the latest software version) in the RCC’s micro SD card reader. Before starting the updating process, the system automatically checks the compatibility between the devices and the software present on the micro SD card. The micro SD card must not be removed until the end of the updating process. If for some reason the updating process is interrupted, reinsert the SD card to let the process finish.
The latest software versions are available on our website www.studer-innotec.com/en/downloads/ under the heading “Softwares and Updates”.
The updating process can take between 3 and 15 minutes. During this period, it is possible that the signalisation LED does not respect exactly the cyclical ratio described.
The updating of a remote control RCC-02/-03, Xcom-232i/-SMS/-LAN/-GSM must be done directly on the connected device.
