Off-grid solar inverters power homes, shops, farms and telecom sites from batteries charged by solar panels. Faults usually show up as batteries not charging, low backup, overload trips or no output at all. Our technicians repair the inverter and check the batteries and charge controller as one system.
Off-grid inverter problems we repair
- Solar inverter battery charging problem — not charging or overcharging
- Low battery voltage cut-off and short backup
- Overload and short-circuit trips
- No AC output or buzzing transformer
- PWM / MPPT charge controller failures
- Burnt MOSFETs and driver circuits
- Display not working or wrong readings
Checking the whole system
A battery charging problem is not always the inverter's fault. Weak or sulphated batteries, wrong battery type settings, loose battery terminals and shaded panels give similar symptoms. We test battery health, solar input and inverter settings before replacing any part.
Frequently asked questions
Why is my solar inverter not charging the battery?
Common causes are a failed charge controller, blown fuse, incorrect battery settings, weak batteries or low solar input due to shading or dirty panels. A technician can isolate the cause with a few measurements.
Can low voltage damage an off-grid inverter?
Repeated deep discharge damages batteries and can stress inverter components. Correct low-voltage cut-off settings protect both.
