Connect the corresponding cable to the port according to the identifier , Make sure the wires
are securely connected.
WARNING:
Be sure that AC power source is disconnected before attempting to hardwire it to the unit.
CAUTION: 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.
3.4 PV Connection
CAUTION: Before connecting to PV modules, please install separately a DC circuit breaker between
inverter and PV modules.
WARNING: All wiring must be performed by a qualified personnel.
WARNING: It’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.
PV Module Selection:
When selecting proper PV modules, please be sure to consider below parameters:
1. Open circuit Voltage (Voc) of PV modules not exceeds max. PV array open circuit voltage of
inverter.
2. Open circuit Voltage (Voc) of PV modules should be higher than min. battery voltage.
CAUTION: 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 off grid solar
inverter will trig overload fault and cut off output to protect your appliance but sometimes it
still causes internal damage to the air conditioner.
