6�4 Connecting the DC Input Cable(PV)
• Do not connect one PV string to more than one inverter at the same time. Otherwise, it may cause
damage to the inverter.
• Confirm the following information before connecting the PV string to the inverter. Otherwise, the
inverter may be damaged permanently or even cause fire and cause personal and property losses.
1. Make sure that the max short circuit current and the max input voltage per MPPT are within
the permissible range.
2. Make sure that the positive pole of the PV string connects to the PV+ of the inverter. And the
negative pole of the PV string connects to the PV- of the inverter.
The PV strings cannot be grounded. Ensure the minimum insulation resistance of the PV string to
the ground meets the minimum insulation resistance requirements before connecting the PV string
to the inverter (R=maximum input voltage/ 30mA).
