[QUOTE="mattonthesea, post: 535997, member: 35809"] Hi I'm about to embark on installing solar flat roof panels DIY. I've sorted out all the theory and just looking for practical pointers. If any of my questions are on a page somewhere could you send me the link. (whenever I search I just get adverts) PV panels on flat roof nearly ready to go. Wiring - not sure on whether parallel or mixture for voltage. 2kW plus, seems quite high for cable current at low voltage (Of course only when bright sun from south in summer! ) Why does a DC battery system not work if mains power interrupted? (I have used small DC system off-grid on a boat) Planning to get qualified sparks in for mains connection. Not worried about any refunds from anyone. Is there a wiring diagram for PV, Inverter, battery etc easily available? TIA [/QUOTE]
