Make sure the wires are securely connected.
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'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.

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.
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.
