One of the units our lab has the most experience with — and with the most complete code database we have built.
We take on the well-known grid-tied REFUsol series:
If your model is not on the list, give us a call — we have most likely seen it before.

REFUsol inverters share their platform with the Siemens SINVERT — Siemens had acquired REFU Elektronik. In practice it is the same unit, with the same faults and the same spare parts.
We take on the power stage, the capacitors, the driver circuits, the relays and the control boards.
We have documented 254 REFUsol error codes, each with its own page: what it means, what the possible causes are and what you can check before calling us.
All REFUsol codes →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 (REFUsol) and are provided unaltered, for information.
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.
