From the SG80KTL in solar parks to the SG250HX — we take on diagnosis and repair in our lab.
We take on the well-known grid-tied SUNGROW series:
If your model is not on the list, give us a call — we have most likely seen it before.
The most common faults we take on: PV insulation fault to ground, grid-side relay errors, overheating and fans, as well as the generic “System Alarm” that cannot be resolved without a diagnosis.
On the SG110, SG250 and SG350 models we specifically repair errors 35 (PV Grounding Fault), 38 (Permanent Relay Fault) and 71 (System Alarm).
We have documented 30 SUNGROW error codes, each with its own page: what it means, what the possible causes are and what you can check before calling us.
All SUNGROW codes →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.
