More than 20 years, in Kalochori, Thessaloniki. Our own electronics lab, dedicated exclusively to solar PV inverters — from the rooftop to the solar park.
When a power board throws an error, the standard answer is to replace the whole board — if it is still available. It often costs as much as a new inverter.
We work one level deeper. We locate the specific component that failed — capacitor, IGBT, relay, driver circuit — replace it and restore the board. That is why we also repair units that are no longer supported.
Every bench has the instruments a real diagnosis needs: an oscilloscope to see what the driver circuit is doing, a bench power supply to run the board outside the unit, a hot-air station and magnification for SMD work.
Five workstations, each with its own equipment, so that several repairs can run in parallel.
A board can pass the bench test and fail again as soon as it is put into real conditions. That is why we deliver nothing that has not first run under simulated operating conditions, with load, just as it will run on the roof or in the solar park.
If it does not pass the test, it goes back to the bench.
Many inverters from 2010–2015 installations are no longer supported by their manufacturer. On our shelves there are boards, transformers and components from those series, sorted and tested.
It is the reason a fifteen-year-old unit can go back into production instead of going for recycling.
When SMA's WebBox units started to fail and there was no replacement, we designed thesolarlink. — our own monitoring device that takes their place without anyone changing inverters.
Designed, programmed and built here.

There is no call centre. When you call +30 2310 607032 you are answered by someone who works on these units every day and can tell you, from the error code alone, what is most likely wrong.
We keep you informed at every stage of the repair, not just at the end.
Tell us the model and the error code and we will tell you what happens next.
