You must protect each inverter with an individual AC
circuit breaker in order to ensure that the inverter can
disconnected safely.
Bore doing any electrical connection, ensure the PV switch, AC and BAT circuit breaker are switched OFF and
cannot be reactivated.
Please ensure that the connector has been
correctly installed.
1. Switch OFF the battery breaker

7.0 Commissioning
To set up the inverter as part of a SunPower Reserve installation, follow the commissioning steps as outlined in the Reserve Safety
and Installation Instructions.
Power ON procedure
1. Switch ON the BATTERY CIRCUIT BREAKER on the right side of the battery. Repeat for additional batteries in sequential order.
2. Switch ON the BATTERY SYSTEM ISOLATOR which is on the left side of the inverter under housing top cover.
3. Press the BATTERY START BUTTON for 1s on BATTERY 1. It is located next to the battery circuit breaker(s). Repeat for additio-
nal batteries in sequential order, within 5s.
4. Switch ON the AC GRID SUPPLY to the inverter.
5. Switch ON the AC BACKUP SUPPLY from the inverter if installed.
6. Switch ON the PV ISOLATOR on the left side of the inverter if PV connected to the inverter directly.
1. Set the Changeover switch to MAINS to supply loads from the GRID, if installed.
2. Switch OFF the AC BACKUP SUPPLY from the inverter if installed.
3. Switch OFF the AC GRID SUPPLY to the inverter.
4. Switch OFF the PV ISOLATOR on the left side of the inverter if PV connected to the inverter directly.
5. Switch OFF the BATTERY SYSTEM ISOLATOR which is on the left side of the inverter.
6. Switch OFF the BATTERY CIRCUIT BREAKER for each battery.
7.
For more information, refer to the Safety and Installation Instructions.
5.
Remove the waterproof caps.
If there is a used terminal, please seal with the cap.
