SunPower Inverter Recall

SunPower has been recently notified by Schneider Electric of a product recall that affects the SunPower SPRx inverter line due to a failure of an internal capacitor located in the wiring box.

If you own a SPRx inverter, use the following instructions to turn your system OFF:


  1. Move the main solar AC circuit breaker to the “OFF” position
  2. Move any external AC and DC disconnects to the “OFF” position
  3. Move the inverter switch to the “OFF” position

Schneider Electric Engineering is preparing a field retrofit kit that will allow customers to have qualified personnel (dealers/installers) replace the suspect capacitors in their inverters with a new set of capacitors.  Retrofit has to be done by qualified personnel. Estimated on-site time is 1 hour.

SunPower will issue a $100 gift card to to homeowners for the inconvenience this recall is causing you. You can visit to claim your gift card.

SunPower is estimating they will receive the retrofit kits in early to mid-March.  Once Sunlight Solar receives these retrofit kits, we will be contacting homeowners to arrange a date/time during which we can replace the defective capacitor(s).

If you need help determining if your system is affected, or if you have any other questions, please call your local Sunlight Solar office.
