Despite all quality assurance measures, faults can occur in exceptional cases. In this case, AEconversion will provide you with the maximum possible support in order to eliminate the fault quickly and free of bureaucratic effort. Please contact our service department directly. A power control is integrated in the inverter depending on the temperature. The following diagrams show the maximum input power of the inverter versus the ambient temperature and air velocity. See diagrams on page 16: - Power reduction Ppv / T ambient 0m/s Air velocity - Power reduction Ppv / T ambient 0.1 m/s air velocity AEconversion -Service Phone: +49 2927 9194-10 In order for our service department to be able to react quickly and correctly, the following information is absolutely necessary. 1) Information on the inverter The details of the type designation, as well as the article number and serial number of the inverter can be found on the type plate of the unit. Brief description of the fault: · Did the fault occur immediately during commissioning or only at a later point in time? · Is the fault reproducible or does it occur sporadically? · What were the ambient conditions (irradiation) at the time of the fault? 2) Information on the PV generator: · Which module manufacturer and module type was installed? · What does the system wiring look like? · What is the open-circuit voltage (Voc) of the module? 4.0 Legal regulations and technical guidelines Please note that the performance of your PV module also decreases with increasing module temperature. As a rule with approx. 0.4% / °C. This means that a module with 330W under STC conditions will only produce a maximum of 271W at 70°C and 1000 W/m². 5.0 Product description The AEconversion micro-inverter is connected directly behind one or two modules, depending on the power specification, and converts the direct current generated into grid-compliant alternating current. The individual conversion at each module enables the solar energy to be optimally utilised. In addition, the micro-inverter solves a widespread problem. Due to the series connection in systems with central or string inverters, the modules are dependent on each other in terms of power. If the power of a single module drops, for example due to partial shading or module mismatch, it negatively affects the power of an entire string. This is referred to as the domino effect. Due to the parallel connection in systems with micro-inverters, the outputs of the modules are independent of each other and allow each module to work at maximum output. The legal regulations and technical guidelines are listed below. 4.1 Derating The service life can be extended by not operating the unit at maximum power, but by reducing this power. This is described below for the micro inverter. 4.1.1 Derating as a function of input voltage The maximum value of the input current from the PV module of 9.5A results in a maximum power that the inverter can convert depending on the input voltage. The limit of 9.5A is limited by the inverter and cannot be exceeded. This results in the following curve of the maximum absorbed power depending on the input voltage of the PV module. The ,,plug-and-play" system avoids connection errors and makes installation simple and safe. There is no dangerously high DC voltage and installation time and costs are significantly reduced. Installations are effective for a wide range, from kilowatts to megawatts, from small family homes to building facades. Each photovoltaic system can be rearranged or upgraded, for example when power is increased or structural changes are made. Zudem wird es durch den Micro-Wechselrichter möglich sein, die Leistungen der Photovoltaik-Anlage auf modularer Basis zu überwachen, was die Voraussetzung für eine genaue Anlagenüberwachung und eventuelle Problemerkennung schafft. So werden nicht nur die Leistungssteigerungen der Photovoltaik-Anlage gewährleistet, sondern auch eventuelle Leistungsverluste durch eine Früherkennung und Problemlokalisierung vermieden. See diagram on page 16 : Power reduction P pv / I pv 4.1.2 Derating as a function of ambient tem. / wind speed Depending on the installation location of the inverter, there are different environmental conditions. The ambient temperature and the air velocity around the inverter influence its performance. The housing of the micro-inverter is IP65 protected and designed for operating temperatures from -25°C to 70°C. If the temperature inside the enclosure exceeds a certain value, the inverter automatically regulates the maximum power to protect itself. Systems with micro-inverters are easy to design and install. Each inverter can be mounted on the mounting rack underneath the PV modules, but it is recommended to have a place where emergency service work can be easily carried out. 6 INV315-50EU 11.2019 Further mounting options are listed in chapter 7.0. An overview of the technical data of the inverter can be found in the appendix on pages 15-16. 5.1 Scope of delivery Included in the scope of delivery: · Inverter 5.2 Dimensions W D Typ INV315-50EU H Width [mm] 385 Depth [mm] 155 Height [mm] 30 INV315-50EU Without mounting 385 109 30 plate 5.3 LED-Display In normal operation, the PV generators produce a voltage as soon as there is sufficient daylight or sunlight. When this voltage is present at the inverter at a certain level and for a corresponding period of time, the inverter begins feeding into the grid. The inverter is equipped with an LED display that provides information on the operating status in the following manner. Feed-in operation: As the power level increases, the flashing frequency of the LED increases. The following flashing frequencies show the percentages as a function of the unit`s power: 0% to 3% 3% to 30% 30% to 60% 60% to 85% 85% to 100% LED 0.5 Sec ,,ON" 2 Sec ,,OFF" LED 0.5 Sec ,,ON" 1 Sec ,,OFF" LED 0.5 Sec ,,ON" 0.5 Sec ,,OFF" LED 0.5 Sec ,,ON" 0.2 Sec ,,OFF" LED continuously ,,ON" Non-feed-in operation: When the inverter is in non-feed-in operation, the LED indicates certain states, which are described below. These can be used for troubleshooting in the event of a fault. Each stage begins with the indication of the following sequence: Sequence starts: 5 sec. ,,ON", 2 sec. ,,OFF" Power stages: Synchronisation in progress: LED 1sec. ,,ON" 0.75sec. ,,OFF ,,0.25sec. 1 cycle AC voltage not within tolerance range: LED 1sec. ,,ON" 0.75sec. ,,OFF ,,0.25sec., 2 cycles DC voltage not within tolerance range: LED 1sec. ,,ON" 0.75sec. ,,OFF ,,0.25sec., 3 cycles AC and DC voltages not within tolerance range: LED 1sec. ,,ON" 0.75sec. ,,OFF ,,0.25sec., 4 cycles Internal overtemperature: LED 1sec. ,,ON" 0.75sec. ,,OFF ,,0.25sec., 5 cycles Sequence ends: 2 sec. ,,AUS" Insulation measurement on the PV side: In feed-in operation, a too low insulation resistance between PV and AC side is signalled with a fast flashing. For this purpose, the flashing frequency for displaying the feed-in power is interrupted every approx. 15s and flashing at a high frequency is set for approx. 2s. 5.4 Protection soncepts The following monitoring and protection concepts are integrated in the AEconversion units of the validity range: · Overvoltage arresters / varistors to protect the power semiconductors · Temperature monitoring · EMC filters to protect the inverter from high-frequency mains interference · Mains-side varistors to earth to protect the inverter from overvoltages · BISI (Bidirectional Safety Interface) Mains monitoring for personal protection and to avoid islanding according to VDE0126-1-1 / VDE AR-N 4105 / IEC 62116 · Insulation monitoring of the PV input 5.5 Network and system protection According to VDE AR-N 4105, the last five fault states of the network and system protection and the set tripping values and tripping times must be readable. For unit versions without communication interface and with integrated fibre optics, the data output is via the LED. For units with communication, the values can also be called up via the integrated interface. 11.2019 INV315-50EU 7 Activate output via fibre optics: · Switch off AC · LED signals the start of the output sequence by ,,ON" for 5 sec. · LED outputs the data as a pulse pattern (duration approx. 50 sec.) · LED signals the end of the output sequence with 5 sec. ,,ON · LED switches to normal signalling mode The LED output sequence must be recorded via a video (smartphone, digital camera, or similar) with a resolution of 680x480DPI. This video is then analysed using PC software. The software can be found on the AEconversion website (http:// aeconversion.com/de/downloads.html). After successful analysis of the video, the set values are displayed in plain text. When recording, make sure that a few seconds of the start and end of the output sequence are recorded. If possible, the position of the LED on the screen must always remain the same. Please observe further instructions when running the software. Additional option for versions with communication interface: · Establish a data connection between the PC and the Micro Inverter · Download AEsolar software · Query the device via the corresponding menu item 6.0 Operating Conditions The selection of the PV generator is of central importance in the design of a PV system. It is essential to ensure that the inverter also matches the PV module. 6.1 Dimensioning the PV generator The number of PV modules connected in series must be selected so that the output voltage of the PV generator does not exceed the permitted input voltage range of the inverter, even at extreme outdoor temperatures. In Central Europe, module temperatures between -20°C and +70°C should be assumed. Depending on the mounting type of the generators and the geographical location, +60°C or +70°C is used in the voltage calculation. You should take the temperature coefficients of the PV modules into account. The following criteria must be fulfilled for the voltage of the PV generator: - Uo (-15°C) < max. input voltage: 50 V and -15°C for an INV315-50EU / RF The open-circuit voltage of the connected PV generator must be within the permitted input voltage range even at very low outdoor temperatures (-15°C). If the temperature is lowered from 25°C to -10°C, the open-circuit voltage of 12 V modules increases by approx. 2.8 V per module (5.6 V for a 24V module). The open-circuit voltage of the entire PV generator must be less than 50 for INV315. - UMpp (+60 °C) > input voltage: 20 VDC for INV315-50EU The UMpp voltage of the connected string should not fall below the permitted input voltage range even at very high module temperatures (+60°C). If the temperature rises from 25°C to 60°C, the UMpp voltage of 12 V modules drops by approx. by approx. 3.6 V per module (7.2 V for a 24 V module). If the UMpp -voltage falls below the permitted input range, the system continues to operate without any problems. In this state, however, the maximum possible power is no longer fed into the grid, but slightly less. It does not harm the inverter if a connected PV generator delivers a higher input current than the maximum usable input current, provided the input voltage is within the permissible range. It may happen that the inverter switches off for safety reasons if the PV generator briefly provides more than the max. DC input power of the inverter, especially during changing cloud cover and relatively low module temperatures. Normally, however, the control of the inverter is so dynamic that it continues to operate without interruption. In general, for an optimal energy yield of the PV generator in Central Europe, a southern orientation with an inclination of 30° should be selected. The optimal power factor for south-facing systems is between 1.10 and 1.25. For an east-west system, the power factor can be selected up to 1.30. The prerequisite is that all other limit values of the inverter are complied with. For exposed locations in the mountains or in southern regions, a corresponding reduction (< 1.15) of the power ratio is necessary. 7.0 Installation Select the mounting position so that the following points are observed: · As good as possible access to the unit for installation work or any service work that may need to be carried out at a later date. . · Ensure a minimum distance of 20 mm between the upper edge of the roof and the underside of the inverter. We also recommend a distance of 25 mm between the back of the PV module and the top edge of the inverter. · The unit is designed to be mounted on the mounting frame under a PV module, but other mounting variants are possible. · The inverter is to be mounted so that the connection area of the inverter faces downwards · The inverter is to be mounted so that the cover (type label) is always facing upwards · The free air flow around the enclosure must not be obstructed. 8 INV315-50EU 11.2019 Due to the PV generator voltage, a higher current flows on the DC side than on the AC side. As a result, with the same cable cross-sections and lengths, the losses on the DC side would be higher. For this reason, it makes sense to place the inverter close to the PV module. The cable lengths on the DC side can thus be kept correspondingly short. For fastening the inverters under a PV module, we recommend the use of suitable accessories depending on the mounting frame, e.g. with slot nuts and M8 screws. 7.2 Installation alternative If mounting on the mounting frame below the PV modules is not possible, another mounting alternative is possible, which is described below: For mounting on the wall, the inverter can be mounted with an appropriate substructure. The substructure must be designed accordingly to guarantee sufficient distance to the wall. 7.1 Installation on PV-racking For mounting on the frame below the PV modules, observe the following: Mark the approximate centre of the PV module on the mounting profile. Fasten the inverter centred on this marking with the help of accessories that are matched to the mounting frame. As an example, slot stones can be fastened to the mounting profiles at the positions below the inverter brackets with screws. When mounting, make sure that the inverter is mounted in the correct installation position: · the cover must face upwards · connection plugs must point downwards 11.2019 8.0 Connections The following sections describe how to make the AC, DC and data transmission connections. When making the connections, the standards and regulations must be followed, as well as the safety instructions contained in these operating instructions. INV315-50EU 9 8.1 Connections overview The connections of the micro inverter are described below. 8.1.1 Connections This circumstance must be taken into account in the AC wiring and when dimensioning the AC line. When using several AC circuits in a PV system, it is necessary to distribute the feed-in phase symmetrically to the three-phase grid. If the PV system consists of more than one inverter, the individual inverters can be connected via connecting lines: 1 AC connector Climatic membrane LED DC connector PVDC connector PV+ 2 34 5 PIN L PIN N L1 (brwon) N (blue) PE (green-yellow) Make sure that you use sufficiently large cable cross-sections to avoid excessive line resistance between the house distribution and the respective inverter. 8.2 AC connection The circuit to which the inverters are connected must be fused with a maximum of 16A. In addition, an earth leakage circuit breaker of min. type A must be provided in the installation. If several inverters are to be operated on one AC connection, the total current must not exceed the current of the fuse. ( max. 16A) DO NOT exceed the maximum permitted number of inverters in an AC circuit as specified in chapter 8.2.1. The plug can accommodate a conductor cross-section of 0.25mm² - 1.5mm² for a flexible cable with wire end ferrules up to 1.0mm². Please note the resulting maximum cable length. Make sure that you use sufficiently large cable cross-sections to avoid excessive line resistance between the house distribution and the respective inverter. Connecting the AC cable assembly to the inverter: Plug the cable coupling together until it clicks into place. Open AC connections at the end of an AC circuit must be closed with a protective sealing cap. To achieve protection class IP65/IP67, all plugs and sockets must be plugged in with the respective mating plugs or closed with protective caps. If the line resistance is high, i.e. if the line length is long on the AC side, the voltage at the mains terminals of the inverter increases during feed-in operation. This voltage is measured by the inverter. If the voltage at the grid terminals exceeds the limit for grid overvoltage, the inverter switches off due to grid overvoltage. 10 INV315-50EU 11.2019 Check the correct locking of the connector with the white arrow pointing to the closed locking symbol. 8.3 DC connection Dangerous touch voltages can occur during the installation of the photovoltaic system. To ensure your safety, please make sure that the DC connection cables of the PV generator do not come into contact with the earth potential. - Risk of damage! Make absolutely sure that the polarity of the connections is correct! - Check the PV generator for earth connection before connecting it to the inverter. · Only use original mating plugs and sockets from the HELIOS H4 product range from Amphenol. · Observe the Amphenol assembly instructions for the DC connectors if you assemble the cables yourself. 8.2.1 AC connection of multiple units Check that the PV generator is free of earth faults before connecting it to the inverter. Before connecting the DC cables to the inverter, check whether the maximum PV module voltage is suitable for feeding into the inverter. If the PV module voltage is too high, the unit will be destroyed. Remember to increase the open-circuit voltage of the solar field at low temperatures! Before installing the PV modules, the inverters should be completely installed and all wiring between the inverters should be completed. If possible, mount the PV modules above the respective inverter on the mounting frame. The connection cables of the PV modules are connected to the inverter via negatively and positively polarised PV plugs and sockets. The AC connection is located on the left side of the connection area and is made via a cable with a 3-pin 16A plug. Two inverters at a time can be connected to the entire circuit via a distribution block. First determine the polarity of the PV module. Connect the positive pole of the module outlet to the input marked ,,+" on the inverter. Connect the negative pole of the PV module output to the input marked ,,-" on the inverter. Up to 9 inverters can be operated on one string (circuit), each equipped with a 16A type B circuit breaker. The distribution blocks are not included in the scope of delivery of the micro inverter. (See Accessories Overview for ordering information). Open AC connections must be closed with a protective cap at the end of an AC circuit. This cap is also not included in the scope of delivery of the micro inverter. (See accessories overview for ordering information) This step is carried out for all remaining PV modules with the inverter attached below, without exceeding the maximum number of inverters in the AC circuit. The exact handling of the DC connections is as follows: 11.2019 INV315-50EU 11 Plug the cable coupling together until it snaps into place. Check for correct engagement by carefully pulling on the cable couplings. Once the connections are fully engaged, check that there are no sharp bends or kinks. PV generator( Module ) Module connection cable Inverter When separating the cable couplings, press the latching tabs together by hand and separate the cable coupling. 8.4 Communication Depending on the communication version of the inverter, different procedures must be followed. Please follow the communication setup procedure that is appropriate for your inverter. 8.4.1 RF-Communication If the micro inverter is equipped with RF communication, the steps for setting up communication, including wiring and monitoring, are described below. Communication via the RFC interface takes place via a frequency of 2.4 GHz. The DC cabling of an inverter with a PV module looks conceptually as follows: In combination with the AEconversion RF gateway, it is possible to set up a simple monitoring network. The following diagram shows how to connect the micro inverters to the gateway: The AEconversion RF gateway is needed to convert the received data to standard RS-485. For more information about the AEconversion RF gateway, see the separate gateway manual. 12 INV315-50EU 11.2019 8.4.2 Without communication Die Micro-Inverter-Versionen ohne Kommunikation sind nicht für eine umfassende Überwachung bestimmt, und können daher nicht durch Anwendung der AEconversion Datalogger, Gateway oder Software verwendet werden. Um die grundlegenden Daten der PV-Anlage überwachen zu können, kann der Anwender einen unabhängigen Energie-Monitor installieren. - Danger to life due to electric shock at live connections! - Even after disconnecting the electrical connections, life-threatening voltages are still present in the inverter. - Therefore, wait at least five minutes before carrying out any further work on the inverter. 11.0 External limiting 9.0 Initial operation and registration with the utility company During commissioning, the inverter must be supplied with PV voltage. To start the inverter, it is also imperative that an AC voltage is applied which is within the respective valid tolerance range. 9.1 Anmeldung beim EVU When registering and accepting the PV system, the modalities of the respective utility grid operator must be observed. Commissioning usually proceeds as follows: · Submission of the documents to the responsible utility company · Installation of the system · Installation of the meter by the utility company 9.2 Acceptance of the plant by the utility company The term ,,external limitation" is understood to mean the remote control of the output power of a PV system by the energy supplier or the energy supply company (EVU). According to the Renewable Energy Sources Act of 01.01.2012 (EEG, §6), external control of the output power must be possible. Depending on the size of the system, 70% control can also be used as an alternative. This external power setting is carried out via ripple control signals. For this purpose, a ripple control receiver must be installed by the utility company. The signals are then forwarded to the data logger. The data logger has four potential-free contacts that are available for processing the ripple control signals and are forwarded to the connected inverters via the RS485 interface. The following documents are generally required for this: · Registration / completion notification by registered installer · Site plan showing the boundaries of the property and the installation site of the PV system · General plan of the entire system with the equipment used (single-pole representation) · Data sheet for self-generating systems · Description of the protective device with information on type, circuit, make and function · Description of the inverter or · Declaration of conformity and clearance certificate · Information on the short-circuit resistance of the switching devices Further information can be found in the installation and operating instructions of the data logger. The power reduction is based on the maximum AC power of the respective inverter in percent. The energy suppliers have currently agreed on four percentage values. The power specifications and their influence on the inverters can be seen in the following table. 10.0 Switching off the inverter You must switch off the inverter for adjustment, maintenance and repair work. Proceed as follows: · Switch off the mains voltage (deactivate the external fuse elements). · After switching off, check that there is no voltage · Follow the local regulations for work on electrical installations. 11.2019 INV315-50EU 13 Standard given by utility company Display inverter Meaning 100% External limitation 100% The maximum possible power is fed in. Normal feed-in operation. No limitation. 60% External limitation 60% of the maximum power 60% is fed in. 12.3 Laws, regulations and technical rules When constructing solar installations, the laws and regulations applicable to the respective country at state, federal and European or international level must be observed. In general, the generally recognised rules of technology apply, which are usually formulated in the form of standards, guidelines, regulations, provisions and technical rules by state and federal organisations, energy supply companies, as well as trade associations and committees for the relevant specialist area. 30% External limitation 30% of the maximum power The installation of solar elements/solar systems must take into 30% is fed in. account the requirements of the roof covering, roof sealing or external wall cladding in accordance with the rules and 0% External limitation External limitation 0% No regulations of the German roofing trade, or corresponding 0% feed-in. national and international guidelines and standards.
