⚠
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 manufacturer of air conditioner
if it's equipped with time-delay function before installation . Otherwise, this inverter/charger
will trig overload fault and cut off output to protect your appliance but sometimes it still
causes internal damage to the air conditioner .
PV Connection
⚠
CAUTION!
Before connecting to PV modules, please install separately a DC circuit breaker between
inverter and PV modules .
ѥ
WARNING!
All wiring must be performed by a qualified personnel .
ѥ
WARNING!
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 .

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 max . battery voltage .
