About EnergyFaults

EnergyFaults is a structured database of error codes, warning codes, warning-light meanings and symptoms for solar inverters, EV chargers, home batteries and heat pumps.

Most fault information is buried in PDFs, forum threads or region-specific support pages. We reorganise that information around the thing you actually have in front of you: a code on a display, a light pattern on a charger, or a device that has stopped working.

• It is not affiliated with, endorsed by, or operated by any manufacturer listed on the site.
• It is not a service company — we do not perform repairs or send technicians.
• It is not a forum, and it is not built from user speculation.

Category → manufacturer → product family → model → fault or symptom. Each fault record carries its own meaning, severity, safe-to-continue guidance, user-safe checks, technician actions and source citations.

The same code can mean different things on different product families. EnergyFaults keeps those meanings separate instead of averaging them into one brand-wide definition.

Corrections, missing codes and documentation pointers are welcome. Use the contact form and include the exact display text of your device where possible.
