PV Module Setup:
When useing PV modules, please be sure to consider below parameters:
1. Open circuit Voltage (Voc) of PV modules didn't exceeds max. PV array open circuit voltage of inverter.
2. Open circuit Voltage (Voc) of PV modules should be higher than min. battery voltage.

Important
Be sure to connect AC wires with correct polarity. If L and N wires are
connected reversely, it may cause utility short-circuited when these
inverters are worked in parallel operation.

Appliances such as air conditioner are required at least 2~3 minutes to
restart because it's required to have enough time to balance refrigerant
gas inside of circuits. If a power shortage occurs and recovers in a short
time, it will cause damage to your connected appliances. To prevent this
kind of damage, please check with manufacturer of air conditioner that if
it's equipped with time-delay function before installation. Otherwise,
this inverter will trigger overload fault and cut off output to protect your
appliance but sometimes it still causes internal damage to the air
conditioner.

Before connecting to PV modules, please install separately a DC circuit
breaker between inverter and PV modules.

All wiring must be performed by qualified personnel.

It's very important for system safety and efficient operation to use
appropriate cable for PV module connection. To reduce risk of injury,
please use the proper recommended cable size as below.
