The SUN2000 dominates newer installations. We take on its diagnosis and board-level repair.
We take on the well-known grid-tied HUAWEI series:
If your model is not on the list, give us a call — we have most likely seen it before.
On the SUN2000 the typical faults that reach us concern the power stage, the insulation measuring circuits, the relays and the power supplies.
The diagnosis is always carried out in the lab, with the inverter under load — because many errors in this family do not show up on the bench without power.
We have documented more than 850 error codes from all manufacturers. See what yours means before calling us.
The whole code database →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.
