Make sure the wires are securely connected.
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.
6.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:
Open circuit Voltage (Voc) of PV modules not exceeds max. PV array
open circuit voltage of inverter.
