Think twice before buying from Solar Panel Energy in Vanderbijlpark. They sell UPS systems with "german" batteries, but 14 months later, your 2400 kwh batteries lasts only 15 seconds into an power outage(and that while drawing 300 watts of power). Upon further enquiry, i'm told that the batteries doesn't have warranty. Support small businesses they say..... R 66 000 down the drain.
