3.6.4 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.
◼
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.

Follow the steps below to complete the PV cable 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.There will be a click sound if connectors are inset correctly into PV plugs.
