Many thanks, greetings

Thank you very much for your reply.
In the case of installing a 200Ah battery, do I have to put cables of more section from the AL120 control unit to the battery? and you have to put fuses of greater resistance?

Good afternoon, I own a 2008 Ford Rimor Katamarano 8 motorhome, I currently have the AL120NB control unit installed, a 100W solar panel and a 100Ah AGM battery. I want to put a new battery with a higher capacity and I wanted to know if I can put a battery with a higher capacity, from 200Ah to 300Ah....
