[QUOTE="revor, post: 502283, member: 23254"] Thanks for that Binky did not think of looking in the tables have got the yellow edition for 17th edition (table 4d4) and have calculated for 55m for the DC run at 10 A it is 1.1% voltage drop and .8% with 10 mm cable. So as concluded earlier not much point going down the 10 mm route. The 15 M from the inverter to the CU at 26 A 230 V comes out at 1.2%. Had in my head that DC needed higher spec cable don't know where it came from. In my teens once worked on fairground rides and remember being told to keep away from the big DC motors that powered the rides as DC more dangerous than AC and I could get "fried". Perhaps came from that time. Got everything spec' d now just need to have the panels as promised and order inverter and battery. My gut tells me could have issue of getting them as promised as not getting my chasing messages returned. Many thanks for your much valued guidance in steering me through this Maze. Much appreciated.
