The grid power may still be present, but the inverter is not draining power from it
since the unit is working in ‘Island Mode’.
You can verify if there is a voltage when the inverter is disconnected from the grid by using a
simple multimeter.
4.8. PV Connection
To avoid any malfunction, do not connect any PV modules with possible current leakage to the
inverter. For example, grounded PV modules will cause current leakage to the inverter.
4.8.1. PV Module Selection
When selecting the PV modules, you should consider the following parameters:
1. Open-Circuit Voltage (Voc) of PV modules does not exceed the maximum PV array Voc.
2. Open-Circuit Voltage (Voc) of PV modules should be higher than minimum start voltage of
the inverter

8/10/12kW 12 AWG 4
Before connecting to PV panels, install a separate DC circuit breaker between the inverter and
PV modules. In addition, we request users install PV junction box with surge protection to pro-
tect the system from lightning strike.
In order to reduce risk of injury, please use the recommended cable sizes as shown below:
