5. 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 AC 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.
PV Connection
CAUTION
: Before connecting to PV modules, please install a DC circuit breaker or DC isolator
of appropriate size 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
size for PV module connection.

PV Module Selection:
When selecting PV modules, please be sure to consider below parameters:
1. Open circuit Voltage (Voc) of PV array can not exceed 145Vdc in the coldest condition.
2. Open circuit Voltage (Voc) of PV array needs to be higher than minimum battery voltage
