Please make sure that the maximum current load of each PV input connector is 18A.
Step 2: Disconnect the circuit breaker and switch off the DC switch.
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 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.
CAUTION: Exceeding the maximum input voltage can destroy the unit!! Check the system before wire connection.
WARNING: Because this inverter is non-isolated, only three types of PV modules are acceptable: single
crystalline and poly crystalline with class A-rated and CIGS modules.
To avoid any malfunction, 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.
CAUTION: It’s required to use PV junction box with surge protection. Otherwise, it will cause damage on
inverter when lightning occurs on PV modules.
