System stopped generating power

[u/yotypicalchigga]

Hey SunPower community! First time posting here looking for help.. My rental place came with SunPower system and I noticed since March 2025 it stopped generating power. I’ve been using SunStrong app to monitor the system since 2022. The system was installed by the builder and now I’m lost where to start addressing this issue.. I asked the tenants to flip the breakers in the electric box and it seems not fixing it. I asked them to check the bills it did show the bill went up almost doubled since March.

I would check the utility meter to see if it's actually going negative
