4.14. PV Connection
Before connecting to PV panels, install a separate DC circuit breaker between the inverter and PV modules.
In addition, we request users install PV junction boxes with surge protection to protect the system from a
lightning strike.
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.
4.14.1. PV Module Selection
When selecting the PV modules, you should consider the following parameters:
1.
Open-Circuit Voltage (Voc) of PV modules does not exceed the maximum PV array Voc.
2.
Open-Circuit Voltage (Voc) of PV modules should be higher than the minimum start voltage of the
inverter.
4.14.2. PV Module Wiring
1. Switch the Grid Supply Main Switch (AC) OFF.
2. Switch the DC isolator OFF.
3. Assemble PV input connector to the inverter.
WARNING
Please do not connect the PV array's positive and negative poles to the ground. This can seriously
damage the inverter.
Before connecting the inverter, please make sure the PV array open-circuit voltage is within the maxi-
mum limit of the inverter.
The correct steps in assembling the DC connector are explained below:
1.
Strip 7mm of the plastic coating off the DC wire and
disassemble the connector cap nut.
2. Crimp metal terminals with crimping pliers.
2. Insert the contact pin into the connector housing until it
locks into place. Then screw the cap nut onto the connector
housing. Torque to 2.5-3 N.m.
