How much does a solar inverter health check cost?

Our full solar system health check costs from £200 including VAT. This covers a complete assessment of your PV system — not just the inverter — including DC string voltage and current testing, AC output measurement, inverter diagnostic, and a written report with recommended next steps.

Do I need to replace my solar inverter if it is showing a fault?

Not necessarily. A fault code or error light does not always mean the inverter needs replacing. Our engineers carry out a full system health check before recommending any replacement. For example, a DC string with no voltage will cause the inverter to fault — but the inverter itself may be perfectly fine, and replacing it would be an unnecessary expense. We diagnose the root cause first.

Which inverter brands do you work with?

We work with all major solar inverter brands including SolarEdge, SMA (Sunny Boy), Fronius, Solis, GivEnergy, Growatt, Huawei SUN2000, Solax, and Enphase microinverters. We are brand agnostic and will recommend the best replacement for your system if one is needed.

How long does solar inverter replacement take?

In most cases, solar inverter replacement can be completed in a single day once parts are confirmed. Our engineers are based in Crawley and cover Sussex and Surrey, giving us fast response times across the region.
