- Final Wiring: Complete all final wiring connections.
Commissioning
Follow these steps for commissioning the inverter:
- DC Connection: Connect the PV+ and PV- cables to the inverter terminals.
- DC Voltage Check: Verify the DC voltage is within the acceptable range (max 1000 VDC).
- PV String Connection: Connect the PV strings to the inverter.
- Cable Preparation: Prepare DC cables by stripping insulation (12 mm strip length, max 7 mm exposed conductor) for 4-10 mm² wires.
- Terminal Connection: Connect PV cables to the inverter terminals (PV1, PV2, BAT).
- DC Voltage Check: Re-verify DC voltage.
- Connector Connection: Connect DC cables using appropriate connectors (+/-).
- Final DC Connection: Ensure final DC connections are secure, torquing to a maximum of 1.5 Nm.
