Important safety instructions This manual contains important information that must be followed during installation and maintenance of the grid-connected photovoltaic inverter (microinverter). To reduce the risk of electric shock and ensure safe installation and operation of the microinverter, the following symbols appear hroughout this document to indicate to hazardous conditions and important safety instructions.

• Recommendation! The external protective ground wire is connected to the protective ground ter- minal of the inverter via the AC connector. When connecting, connect the AC connector first to ensure that the inverter is grounded, and then make the DC connection. When disconnecting, disconnect the AC power by opening the branch circuit breaker first, but keep the protective ground wire in the branch circuit breaker, connect to the inverter, and then disconnect the DC inputs.

Microinverter installation A PV system using microinverters is simple to install. Each microinverter can be easily mounted on a mounting system directly under the photovoltaic modules. DC wires connect the PV module directly to the microinverter which eliminates the presence of high DC voltage. Installation MUST comply with local and technical codes.

Installation Procedures Step 1 - Install the AC splitter box a) Install the appropriate junction box in a suitable location (called a hub) near the microinverter chains. b) Connect the end of the AC cable to the junction box with a suitable choke or connector.

WARNING: Before installing any of the microinverters, check that the voltage at the connection point matches the voltage rating on the microinverter label. WARNING: Do not place inverters (including DC and AC connectors) in areas exposed to sun, rain, or snow. Maintain spacing between modules. Leave at least 3/4’...

Step 4 - Install a protective cap for the AC cable at the end of the AC cable. Step 5 - Connect microinverters to photovoltaic modules. WARNING: When the DC cables are connected the microinverter should immediately flash one quick red and three times the green LED. This will happen as soon as the cables are connected which will show that the microinverter is working properly.
3. The devices should start blinking red one minute after the AC power switch is turned on. The blue LED then flashes. This means, This means they are gene- rating power normally, a faster flashing blue LED means more power is being generated.

GFDI error A quadruple red LED indicates that the microinverter has detected a ground fault device interrupt (GFDI) error in the photovoltaic system. Unless the GFDI error is corrected, the LED will flash four times Other Faults All other faults are reported to the ECD. A list of additional faults and troubleshooting procedures can be found in the in the ECD installation and operation manual.

To troubleshoot a non-functioning mikiroinverter, perform the following steps in order: 1. Check that the mains voltage and frequency are within the ranges shown in the Technical Data section of this manual. 2. Check the connection to the power grid. Check that the line voltage is present at the inverter in question by removing the AC current and then the DC current.
Maintenance No maintenance is required. Microinverter replacement Follow the procedure to replace a defective Microchip 1. Disconnect the microinverter from the photovoltaic module in the order shown below: 1.1. Disconnect the AC by turning off the branch circuit breaker. 1.2. Disconnect the AC connector of the microinverter. 1.3.
