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.
Max. Input Current (A)
12.5A/12.5A

The minimum isolation resistance to ground of the PV string must exceed 33.33kΩ in case
of any shock hazard.
Note: BAT plugs are similar with PV plugs, please confirm before use it.
Follow the steps below to complete the PV connection:
1
）
Prepare PV cables and PV plugs.
Note: Please use PV plugs and connectors in accessory box.
2
）
Connect PV cable to PV connectors.
Note:
1.
PV cable must be tightly crimped into the connectors.
2.
For Amphenol connector, the limit buckle cannot be pressed.
3.
T here will be a click sound if connectors are inset correctly into PV plugs.
