WARNING:
Be sure that AC power source is disconnected before attempting to hardwire it to the unit.
4.
Then, insert AC output wires according to polarities indicated on terminal block and tighten terminal
screws. Be sure to connect PE protective conductor (
) first.

Make sure the wires are securely connected.
PV Connection
CAUTION: Before connecting to PV modules, please install separately DC circuit breakers between inverter
and PV modules.
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 shown below.

WARNING: Because this inverter is non-isolated, are accepted: single crystalline, poly crystalline with class A-
rated and CIGS modules.
To avoid any malfunctions, do not connect any PV modules with possible current
leakage to the inverter. For example, grounded PV modules will cause current leakage to the inverter. When
using CIGS modules, please be sure NO grounding connection.
CAUTION: It’s requested to use PV junction box with surge protection. Otherwise, it will cause damage on
inverter when lightning occurs on PV modules.
CAUTION: Appliances such as air conditioner requires 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 be trigger overload fault and cut off output to protect your appliance but sometimes
it still causes internal damage to the air conditioner.
