Just finished mounting a pair of 395w panels to the roof of my RV, and want to make sure I get the wiring correct to the SCC.
Panels will be wired in parallel to a Victron 100/50 SCC.
49.5 Voc
41.4 Vmp
10.23 Isc
9.55 Imp
Max Series Fuse 20A
Planning on using wire sizes below.
Panels have 5ft 12ga leads, then 6ft to combiner box - 10ga.
Combiner box to breakers then SCC about 15ft - 8ga.
SCC to breakers then main battery bus bars about 5ft - 6ga.
Will be using DC breakers just before and just after the SCC (basement storage), both are 500v 32a coming into SCC, and 63a coming out.
With the breakers do I still need a fuse for each panel on the roof, and if so should the fuses be 20a?
My DC bus bar negative is grounded to the frame of the RV is that enough for panel ground, or should I have a third wire attached to the frame of the panels and if so what size?
Can I use a short wire from the panels to the combiner box ground connection?
Thanks for all advice
