Which models

From the Sunny Boy on the roof to the Sunny Central in the solar park

We take on the well-known grid-tied SMA series:

  • Sunny Boy — single-phase rooftop inverters, from the old SB series to the TL
  • Sunny Tripower — three-phase STP, from 5000TL to 25000TL and the newer series
  • Sunny Mini Central — SMC 6000A, 7000HV, 8000TL, 9000TL, 10000TL, 11000TL
  • Sunny Island — off-grid and hybrid systems
  • Sunny Central — central inverters for solar parks
  • Windy Boy — and older series no longer supported

If your model is not on the list, give us a call — we have most likely seen it before.

What we repair

The board, not the box

The faults that reach our bench are almost always electronic: worn DC-link capacitors, power transistors and driver circuits, grid relays that fail the self-test, insulation and leakage current measuring circuits, power supplies and fans.

All of these are repaired at component level. No new board is needed — and often there is no new board to buy anyway.

Manufacturer manuals

SMA manuals in PDF

The manufacturer's manuals for the models we see most often on the bench — for wiring, settings and interpreting the display messages.

The manuals belong to the manufacturer (SMA Solar Technology) and are provided unaltered, for information.

How we work

You learn what is wrong and what it costs before the repair begins

You send or bring us the inverter. The diagnosis is usually completed within 48 hours and we inform you in detail. The repair starts only after you approve it.

If the repair goes ahead, the diagnosis is free of charge. If the unit cannot be repaired, nothing is charged.

Before it leaves the lab, every inverter is tested under load in simulated operating conditions, and comes with a six-month warranty on the whole unit.

Do you have a SMA that is not producing?

Tell us the model and the error code and we will tell you straight away what is most likely wrong and what happens next.
