I look into my crystal ball and foresee many a messed up Solar PV grid tied solar installation coming to a rooftop in Gauteng, done by business men not electricians, soon.......

Already had a laugh at one guy who didn't see the need to use DC isolators, rather go for the cheaper AC one to isolate his Solar panels from his inverter. Better for the profit margin. He now knows that DC arcs better than AC. Shouldn't have laughed.... But did. They need to get some regs out on this because I'm seeing quite few of these things going in now.

Anyone on here doing Grid tie yet?????
