Last year I was offered a used / refurbished Inverter by a Randburg based business. Preferring not to go for any of the newer cheap inverters I decided to go for a Axpert 5kw - Open Range Solar as I already have an 7 year in service Mecer 5kw also running.
After first not working when I installed it, the seller 'repaired' it. Now the unit worked - with a noisy fan - but anything above 3kw output it would stop working - error 51.
The seller refused to look into it claiming that it is the installers fault. I took it to a reputable repairer and it was repaired in one day.
The repairer stated that some parts were missing and some crucial diode was of wrong value - photos of board as found inside attached.
I am thinking of 'going after' the seller, but thought it would be wise to get more opinion on the state of the inverter as bought.
Please comment on the photos.
