Question 1

How much does a solar inverter health check cost?

Accepted Answer

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.

Question 2

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

Accepted Answer

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.

Question 3

Which inverter brands do you work with?

Accepted Answer

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.

Question 4

How long does solar inverter replacement take?

Accepted Answer

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.

Question 5

Is Electrotec MCS certified for inverter replacement?

Accepted Answer

Yes. All inverter replacement work carried out by Electrotec Power Solutions is MCS certified. This is important because it protects your eligibility for the Smart Export Guarantee (SEG) and ensures your system warranties remain valid after the replacement.

Question 6

Do you cover areas outside Crawley for solar inverter work?

Accepted Answer

Yes. We cover solar inverter replacement and repair across Crawley, Horsham, Haywards Heath, Reigate, Dorking, Guildford, Brighton, Chichester, Worthing, East Grinstead, and the wider Sussex and Surrey region.
