THE SHORT ANSWER
A battery that no longer charges from solar may involve settings, production, wiring, permissions or equipment. Preserve the post-service state before requesting changes.
Establish the before-and-after state
Record the last normal charging date, service date, work order and first abnormal interval. Save battery state, solar production and household load on the same screen or timestamp. Do not rely on memory that it “always charged by noon.”
Capture operating settings
Save reserve level, operating mode, schedules and any permission or grid-services message visible to the owner. DOE treats storage as a distinct system decision tied to household goals. [1] Do not change several settings at once while troubleshooting.
Confirm solar is available
Compare array production and battery charge power during suitable daylight conditions. A low-solar day, high household load or curtailed system can leave little energy for storage. Label observations; do not claim the installer disconnected the battery without field evidence.
Review the service scope
Ask what equipment, breakers, sensors, firmware, wiring or monitoring configuration changed. DOE maintenance guidance supports documenting corrective work and resulting performance. [2] Provide the technician with screenshots taken immediately after service rather than only the current state.
Recommission a clear baseline
After correction, verify charging, discharging, backup reserve and app reporting across more than one operating period. Save final settings and replaced serials. A successful charge cycle confirms observed function, not guaranteed daily solar energy or outage runtime.
Before your next conversation
- Align service and symptom dates.
- Save battery mode and reserve.
- Compare solar, load and charging.
- Retain final settings and service report.
