Victron 100/30 vs Victron 100/20?
Ok, if I add another Zamp 90W solar panel to the roof of my new Bambi (to have 180W), I know I can easily get by with the 100/20 to replace the Atkinson stock unit. I have a portable Zamp 180W suitcase as well and might consider wiring the Zamp umbilical to the charge controller instead of directly to the battery (as is stock). In which case seems the 100/30 would be more suitable. But say I buy the 100/30, install and use with the 180W rooftop and then never rewire the umbilical directly to the inside charge controller. Is there then a downside to having the 100/30 just for the 180W rooftop? Other than fact I will have spent about $50 more for it? Is there a mechanical/electrical downside? thx, stephen
