[QUOTE="sw15, post: 546918, member: 36685"] I have got some ideas from they guy selling some high tech solar/battery/grid UPS on ebay. The enclaosed image is just part of his system. He states on his stickers: Caution - when AC out is inverter supplied earth and neutral are bonded. He has 2 HS1-25 relays. I think he uses one to switch between the two supplies - both live and neutral, and the other to connect the neutral to the earth when grid goes down. But I am not 100% sure. And I'm not 100% sure if the relay to connect the earth to the neutral is necassary. [ATTACH type="full" alt="ebayer.GIF"]15672[/ATTACH]ng on eBay [/QUOTE]
