1. Switch the Grid Supply Main Switch(AC)OFF.
2. Switch the DC lsolator OFF.
3. Assemble PV input connector to the inverter.
Safety Hint:
When using PV modules, please ensure the PV+ & PV- of solar panel is not
connected to the system ground bar.
Safety Hint:
Before connec�ng inverter, please make sure the PV array open circuit voltage is
within the 800V of the inverter.
Note:
This inverter complies with IEC 62109-2 clause 13.9 for earth fault alarm
monitoring. If an Earth Fault Alarm occurs,the inverter will not connect to the
grid and will report an error F04 on its LCD.At the same �me, the buzzer will
sound.
Safety Hint:
Before connec�on, please make sure the polarity of the output voltage of PV
array matches the “DC+” and “DC-” symbols.
