Hybrid solar inverters manage solar panels, batteries and the grid at the same time, which makes them more complex to diagnose. Sunce Renewables repairs hybrid inverters and resolves battery, BMS communication and backup switching faults.
Hybrid inverter faults we handle
- Battery not detected or BMS communication errors with lithium batteries
- Backup (EPS) output not switching during power cuts
- Battery charge / discharge current problems
- Grid export and zero-export / CT meter errors
- DC-DC converter and bidirectional stage failures
- Firmware and configuration issues
Configuration matters
A large share of hybrid inverter complaints are configuration problems — wrong battery type, wrong CT direction or incorrect work mode. We check settings and wiring first, and repair hardware only where it has actually failed.
Frequently asked questions
Why is my hybrid inverter not giving backup during a power cut?
The backup output may be disabled in settings, the battery may be below its discharge limit, or the transfer relay may be faulty. We diagnose each in turn.
