To operate a SunPower inverter:
1. Turn the PV Array DC Isolator to the “ON” position. 2. Ensure any external DC or AC disconnects are also in the “ON” position. 3. Move the inverter AC Main Switch (Inverter Supply) to the “ON” position. This may be labeled “I” on some models.
To check if it’s working properly, use the inverter’s LCD display and LED lights. During daylight, it shows:
- “E-Today”: Energy produced today (in kWh) - “Pac” and “Upv”: Instant AC power output and DC input voltage - “E-Total” and “h-Total”: Total energy and operating hours since installation
For emergencies, turn off the inverter only after reaching safety, and contact SunPower or your SunPower Partner for assistance restarting the system.
