Used Growatt inverter SPF 3000TL for sale. Two years old. Everything works except it no longer processes PV voltage or wattage from panels. Think there is a charging circuit burnout because when it used to function, a plastic odour was present and became worse as PV wattage increased. Tried for warranty servicing, what a joke! Back and forth for 3 months and no resolution. Tried factory resets, firmware updates didn't work because it won't interface with downloaded software programs. No recognition of com ports, etc. Not a plug and play unit by any stretch of imagination. Totally frustrated by this company, as I found many are through meriads of reviews. They can't even provide an address of competent repairs facilities. I guess it's junk once it malfunctions after the 3 year warranty. What's it worth? Ideas?
