1. Confirm the following information before connecting the PV module to the inverter.
Otherwise, the inverter may be damaged permanently or even cause fire and cause personal
and property losses.
• Make sure that the max short circuit current and the max input voltage per MPPT are
within the permissible range.
• Make sure that the positive pole of the PV module connects to the PV+ of the inverter. And
the negative pole of the PV module connects to the PV- of the inverter.
2. Do not plug or unplug the connectors when the inverter is running.
1. Connect the PV cables using the MC4 PV connectors. The manufacturer shall not be liable for
the damage if other connectors are used.
2. The PV modules cannot be grounded. Ensure the minimum isolation resistance of string to
the ground meets the minimum isolation resistance requirements before connecting the PV
module to the inverter.
3. Connect the connectors of the same PV module to the same pair of PV connectors on the
inverter.
4. Recommended PV module specifications:
GW1600-MIS: 0W~540W; 1800-MIS: 0W~600W; 2000: 0W~670W.
5. DC extension cable can be used if necessary. Recommended specifications: 4-6mm
Seal the PV connectors using waterproof covers when they are not to be used. Otherwise, the
