Had a sunsync inverter installed but it was faulty as there was smoke and installer took it to company for review on guaranteed inverter to see if must be replaced or repaired - now without electricity as from first week of February up till now - paid hell of a price and have to wait and wait as stage 6 and stage 3 was already going on with government who had us on knees without caring that is why we choose solar but no security on what a person going to get on solar panels/inverter/batteries/cables as it burn!! WHY is TURN AROUND TIME AT TECHNICIANS of SA solar SUNSYNC SO SO LONG to get an answer?????
