Electrical Connection
Warning:
Note:
The fatal high voltage may on the DC side, please comply
with electric safety when connecting.
Please make sure the correct polarity of the cable connected
with inverter, otherwise inverter could be damaged.
PV cable suggestion
Cross-section
4mm²
The inverter is equipped with 2 MPPT channels, each of which contains a PV string input.
For the best results, make sure that each MPPT channel is correctly connected with PV string. Other-
wise, the inverter will activate voltage or current protection automatically.
Please make sure below requirements are followed:
•
The open-circuit voltage and short-circuit current of PV string should not exceed the reasonable
range of the inverters.
•
The isolation resistance between PV string and ground must exceed 10 kΩ.
•
The polarity of PV strings are correct.
•
Use the DC plugs in the accessory.
•
The lightning protector should be equipped between PV string and inverter.
•
Disconnect all of the PV (DC) switch during wiring.
