3.5 PV Connection
3. Then, insert AC output wires according to polarities indicated on the terminal block and tighten
terminal. Be sure to connect corresponding N wires and PE wires to related terminals as well.
4. Make sure the wires are securely connected.
5. Appliances such as air conditioner are required at least 2-3 minutes to restart because it is
required to have enough time to balance refrigerant gas inside of circuit. If a power shortage
occurs and recovers in short time, it will cause damage to your connected appliances. To
prevent this kind of damage, please check manufacturer of air conditioner if it is equipped with
time-delay function before installation. Otherwise, this inverter will trigger overload fault and
cut off output to protect your appliance but sometimes it still causes internal damage to the air
conditioner
Before connecting to PV modules, please install a separately DC circuit breaker between
inverter and PV modules. It is 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.
Chart 3-4 Cable size
Be sure that AC power source is disconnected before attempting to wire it to the
unit.
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 PV modules, please be sure NO grounding.
It is requested to use PV junction box with surge protection. Otherwise, it will
cause damage on inverter when lightning occurs on PV modules.
