hi all I would really appreciate help on this
I have a victron 100/20 MPPT I also have 2 off 230w mono panels which I plan to wire in series 10m max run in likely 6mm cable
each panel is identical spec and im in England so im gonna get plenty of cloudy days but some decent sun as well hopefully
max current imp 10.8A
max voltage vps 21.2v
short circuit current isc 11.5A
open circuit voltage voc 25.6v
so I am checking the mppt is correct and I have been advised to use a 100/30 100/50 75/15 by different people , I basically want the most efficient option I understand that the units will limit the current and all will actually do the job , I dont plan on installing any more solar as its on a van roof with limited space , im leaning towards swapping it for a 100/30 , is there any real benefit in doing this and pls explain what this would be in real terms
please help any techys
