Solar System Service & Troubleshooting
When Your Solar System Isn’t Working Right — We’re the Ones to Call
Solar should just work. But if your system is offline, underperforming, or throwing mysterious inverter errors — we’re here to help. At Menderix, we provide fast, honest troubleshooting and solar repair across Sacramento and the Greater Sacramento Area, no matter who installed your system.
If your Enphase Enlighten app shows “no production”, your Sol-Ark inverter won’t charge your batteries, or your Tesla Powerwall is stuck offline after a utility outage — we’ve seen it before, and we know how to fix it.

Not Sure What the Problem Is?
Here’s what we often hear from homeowners:
- “My system used to save me money, now my bill looks the same.”
- “The solar app stopped updating months ago.”
- “PG&E says I’m exporting, but I don’t see credits.”
- “Something changed after a roof or electrical upgrade.”
These aren’t just minor annoyances — they could signal major energy loss, inverter failure, or even fire risk. We’ll find the root cause and walk you through the fix.
