3.3 Installation procedure Step 1: Unpack and check
Check the controller for transport damage and bumps; Check whether the specifications are consistent with the order.
Step 2: Check the controller parameter limits Ensure that the solar array open circuit voltage (Voc) under the maximum temperature compensation state does not exceed the MPPT rated voltage value of the model. Multiple controllers can be mounted in parallel on the same battery pack for greater charging current. Each MPPT in parallel must be connected to an independent solar panel.
Step 3: Determine the installation space To ensure room for air circulation, leave at least 30 cm (12 in) above and below the controller, and 5 cm (2 in) on the side, and do not install it in a closed box. As shown in the figure.
Note: Leave enough space between the top and bottom for the fan to dissipate heat. Step 4: Wiring sequence Connect the input and output cables connected to the circuit breakers to their corresponding positions on the controller in sequence. Ensure that the circuit breaker is off before connecting the cables. As shown below.

4.7 Charging status and parameters
4.7.1 The controller charges the lead-acid battery
The MPPT controller has a 4-stage battery charging algorithm for fast, efficient and safe charging of lead-acid batteries. 1 – CC State (Constant Current Charging): Fast Charging Phase – FAST 2 – CV state (constant voltage charging): regulated charging phase – KEEP 3 – CF Status (Float Charging): Prevents the battery from being overcharged for a long time. And make up for the loss of self-discharge. -FULL 4 Boost charging: activate battery chemistry, desulphurization effect
4.7.2 The controller charges the lithium-ion battery
The MPPT controller will charge according to the specifications of the lithium-ion battery, mainly in two stages. In the first stage, when the battery voltage is lower than the saturation voltage, it will rapidly charge according to the maximum power point that is tracked; in the second stage, when the battery voltage is equal to the saturation voltage, it will charge at a constant voltage, and the charging current will gradually decrease to 0.

4.8 Load Control
The main purpose of the load control function is to disconnect the system load when the battery is discharged to a low voltage state and reconnect the system load when the battery is charged back to a certain level. System loads can be lamps, DC appliances, or other electronic equipment. The total current of all loads must not exceed the MPPT maximum load rating.
Reminder: Risk of Equipment Damage Do not connect any AC inverter to the load terminals of the MPPT. The load control circuit may be damaged. The inverter should be connected to the battery. If any other load may sometimes exceed the maximum voltage or current limit, the device should be connected directly to the battery or battery pack.
Brief description of load control:
· Do not connect multiple MPPT load outputs in parallel to power supply dc loads that ·consume more than 30A current, depending on the MPPT model used.
Be careful when connecting loads with specific polarities to controller load terminals. Reverse polarity connections may damage the load. Be sure to check the load connection
·carefully before powering on. The load output voltage of the controller is the same as that of the battery string. For
·example, when the battery voltage is 25.2V, the load output voltage is also 25.2V. When the load output current is lower than the rated load current, the system provides
·stable power to the load. When the load output current exceeds the preset load current and lasts for 5 minutes in the
·range of 100% to 120%, the load output is shut down and switches to the normal off mode. When the load output current is detected to exceed 120% of the rated load current, the load output will be shut down immediately and switch to the normal off mode.
Attention: When the Load switches to normal off mode, in order to restart the Load, the user needs to reset the Load to “ON” mode ON the controller or reset the Load mode through the mobile APP, upper computer, and meter header.

Load Control Mode: 1 – Normal on/Normal Off mode: The load output state is on or off. 2 – Optical control mode: The load output is turned on or off according to whether there is light (input voltage limit). Refer to the following diagram for the working mechanism. 3 – Dual-period timing control mode: The load switch of two different periods is controlled according to two timers. Refer to the following diagram for the working mechanism. 4 – Fixed time light control mode: according to whether there is light (input voltage limit), the load output is controlled to turn on or off in hourly units.
Attention: Only the normal ON/normal OFF mode can be set on the controller panel. Other modes need to be set through other optional accessories. 4.9 communication 4.9.1 Apply All operations of this series of controllers can be done via Bluetooth /wifi modules. Users can search for “SolarMate” in the AppStore or GooglePlay to download and install the app, or obtain the installation package directly from the website.

5.0 Common faults and handling
5.1 Common fault 1.The LCD screen doesn’t light up, and the controller doesn’t seem to be powered on. Solution: Use a multimeter to check the voltage of the battery terminals on the MPPT. The battery voltage must be 10 VDC or higher. If the voltage on the controller battery terminal is between 10 and 60 VDC and no indicator light is on, contact the authorized distributor for repair. If the voltage is not measured, check the wiring, fuses, and circuit breakers. 2.The controller is not charging. Solution: Check fuses, circuit breakers, and wiring connections in power wiring. Using a multimeter, check the array voltage directly on the MPPT solar input terminals. Before starting charging, the input voltage must be greater than the battery voltage. Check whether the battery voltage displayed on the LCD screen is within the recognition range of the controller system.
3.The battery has been in a low or dead state for a long time. Solution: Possible reasons: 1. There are too few solar panels to generate enough energy to meet the system use, and the solar panel array can be increased appropriately. 2. The battery capacity is too small to store enough energy for the system to use, and the capacity of the battery pack can be appropriately increased.
Warning: Inputs and outputs are not electrically isolated and may be energized using dangerous solar voltages. Under certain fault conditions, the battery may be overcharged. Before contact, take protective insulation measures. Warning: Devices must be installed to disconnect all power supply electrodes, and these disconnections must be included in the fixed wiring. Before maintaining or removing controller connections, disconnect all power devices.

6.0 Product protection function and system maintenance
6.1 Protection function description Waterproof and dustproof protectionIP21 Waterproof grade: 2, dust grade: 1 Battery reverse protection After the positive and negative terminals of the battery are reversed, the system does not work and will not burn out the controller.
Note: When the photovoltaic input is connected and running, it is not allowed to reverse the battery, otherwise the equipment is abnormal or damaged, you will not enjoy the warranty service.
Photovoltaic input short circuit protection When the input end of the photovoltaic array is short circuited, the controller disconnects the charging. When the short circuit is cleared, the charging will automatically resume. Photovoltaic input reverse protection When the photovoltaic array polarity is reversed, the controller will not be damaged, and will continue to work normally after correcting the wiring error. Internal overtemperature protection When the internal temperature of the controller reaches the specified threshold, the power is automatically reduced. Radiator temperature limit When the heat sink temperature exceeds the maximum threshold, the controller automatically power off and stops running. Battery drop protection When the battery is in the overcharge state, the charging circuit will automatically fall off and disconnect, preventing overcharge and extending the battery life.
Note: There is no GFDI (Ground fault detection device) inside the controller.
6.2 System maintenance
· In order to maintain the best performance, it is recommended to inspect the project more than ·twice a year.
Make sure the airflow around the controller is not blocked and remove any dirt or debris from the radiator Check all exposed wires for insulation damage caused by sun exposure, friction with other objects around, dry rot, insects or rodents. Wires need to be repaired or replaced as
·necessary. Verify that the indicator is consistent with the device operation. Please note any faults or errors
·displayed and take corrective action if necessary. Check all terminals for signs of corrosion, insulation damage, high temperature, or burning/
·discoloration, and tighten the terminal screws. Check for dirt, nesting insects and corrosion and clean as required.
Warning: Electric shock danger! When performing the above operations, ensure that all power supplies of the controller are disconnected, and then perform the corresponding check or operation!
