[QUOTE="ruggedscot, post: 533703, member: 35189"] DC is formidable - And it has to have properly rated switchgear. not just for breaking a fault, but for switching duties. below demonstration. [MEDIA=youtube]Zez2r1RPpWY[/MEDIA] A 2.5kw load on ac and then dc.... you can see why you really need to have the correct specification. You also need to take into consideration the fault levels that would be present. DC batteries are well known for the potential to provide several thousand amps. And in some farms where you have series and parallel combinations then you can run a risk fault currents that could obliterate a poorly designed installation. [/QUOTE]
