Mastervolt inverter repair

Dutch units from the early years of solar PV in Greece. We take on the Soladin and the Sunmaster as a matter of course.

Which models

Soladin and Sunmaster

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

  • Soladin — small single-phase rooftop inverters
  • Sunmaster XS — single-phase string inverters
  • Sunmaster QS / CS — higher power
  • Sunmaster TL — the transformerless series

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

These are units more than a decade old, no longer supported. Their faults are typical of their age: capacitors, power supplies, power stage and relays.

If the unit is in good mechanical condition, repair is almost always preferable to replacement.

Error code database

Looking for a specific code?

We have documented more than 850 error codes from all manufacturers, each with its own page. If your inverter is showing a code, start there.

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.
