3.5 Electrical Connection
The inverter is equipped with 3 MPPT channels, and each channel contains 4
PV string inputs. For best results, make sure that each MPPT channel is
connected to a PV string separately. Otherwise, the inverter will automatically
activate voltage or current protection.
·The open-circuit voltage and short-circuit current of PV string must not exceed
inverter’s range
·The isolation resistance between PV string and ground must exceed 10 kΩ
·The polarity from PV strings are correct
·Use the DC plugs in the accessory
·The lightning protector should be equipped between PV strings and inverter
·Disconnect all of the PV (DC) switch during wiring

Warning:
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.
