5. Make sure the wires are securely connected.
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.
WARNING! All wiring must be performed by a qualified person.
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 min. battery voltage.
Max. PV Array Open Circuit Voltage
PV Array MPPT Voltage Range
Min. battery voltage for PV charge
Please follow below steps to implement PV module connection:
1. Remove insulation sleeve 10 mm for positive and negative conductors
2. Check correct polarity of connection cable from PV modules and PV input
connectors. Then, connect positive pole (+) of connection cable to positive
pole (+) of PV input connector. Connect negative pole (-) of connection cable
to negative pole (-) of PV input connector.
CAUTION: Important
Be sure to connect AC wires with correct polarity. If L and N wires are connected reversely, it may cause AC
short-circuit when these inverters are worked in parallel operation.
