βοΈπ **Solar battery not working? It might not need replacing.**
When a home battery stops charging, starts clicking, shuts down unexpectedly or seems to be losing capacity, it's easy to assume the battery itself has failed.
But that's not always what's happening.
A solar battery system has several potential points of failure, including the battery cells, BMS (Battery Management System), control boards, inverter and system configuration.
That means two batteries showing exactly the same symptoms can need completely different fixes.
Common problems we see include:
π§ BMS and control board faults
β‘ Grid-charging and configuration issues
π Relay clicking and failed self-tests
π Apparent capacity loss
βοΈ Inverter settings and communication faults
π Genuine cell degradation
At **Recover**, we take a **diagnosis-first approach**.
More than **60% of the batteries that come to us are repaired**, because many faults can be traced to the BMS, electronics or other repairable components rather than the battery cells themselves.
Before accepting that an expensive battery needs replacing, find out what's actually wrong with it.
β»οΈ **Diagnose. Repair where possible. Replace only when necessary.**
