Security screw
For the best results, make sure that each MPPT channel is correctly connected
with PV string. Otherwise, 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 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.
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.
