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.
• Connect the DC cables using the delivered PV connectors. The manufacturer shall not be

• The PV strings cannot be grounded. Ensure the minimum isolation resistance of the
PV string to the ground meets the minimum isolation resistance requirements before
connecting the PV string to the inverter.
• The DC input cable should be prepared by customers.
