Frequently asked questions
Do you repair out-of-warranty SMA solar inverters?
Yes. Out-of-warranty SMA inverters are repaired at component level, which is usually much cheaper than replacing the inverter.
My SMA inverter shows an error code — can you help?
Send us the error code and a photo of the display on WhatsApp. Many SMA errors are caused by site conditions and can be resolved without opening the inverter; others need workshop repair.
