Powador and blueplanet — German units with a long service life, well worth repairing rather than replacing.
We take on the well-known grid-tied KACO series:
If your model is not on the list, give us a call — we have most likely seen it before.
On KACO units we often see worn DC-link capacitors, power stage faults, self-test and relay errors, as well as problems in the measuring circuits.
The older series are among the most worthwhile repairs: replacing the unit costs many times more than restoring it.
We have documented 62 KACO error codes, each with its own page: what it means, what the possible causes are and what you can check before calling us.
All KACO 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 (KACO new energy) 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.
