Be sure that AC power source is disconnected before attempting to wire it

to the unit.

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

3.5 PV Connection

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.

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.

3.5.1 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. start voltage.

3.5.2 PV Module Wire Connection:

Please follow below steps to implement PV module connection:

1. Remove insulation sleeve 10 mm for positive and negative conductors.

2. Suggest to put bootlace ferrules on the end of positive and negative wires with a proper

crimping tool.

3. Check correct polarity of wire connection from PV modules and PV input connectors.

Then, connect positive pole (+) of connection wire to positive pole (+) of PV input

connector. Connect negative pole (-) of connection wire to negative pole(-)of PV input

connector.Close the switch and make sure the wires are tightly fixed.
