Hi, I am looking to buy an 8KW inverter but alread have issues with a 1KW Axpert inverter I bought over the internet form a supplier in Jhb. So if I want to invest 50 or 60 k I would prefer to buy from a reputable supplier, one that can repair inverters at least. Any advice will be appreciated. Or do I just insure it and if there is a problem claim from insurance.
