3.5 Electrical Connection
The inverter is equipped with 2 MPPT channels, each of which contains a PV
string input. For best results, please ensure that each MPPT channel is
connected to a PV string separately. Otherwise, the inverter will activate voltage
or automatic 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
