Hi folks I'm trying to decide best value for money so I thought id ask the forums opinion, my batteries need replacing before we head out for the summer so as I'm buying new ones I'm bit more bothered than than I used to be about looking after them. Everything onboard is 12v except the washer, currently we run this through a sterling 3 kw inverter whilst we're moving ( isuzu 42 with twin 70a alternators)I appreciate a genny would probably be best but I don't want the hassle of petrol, so would my cash be best spent on a smartgauge and smartbank to parallel the alternators I have or should I get a larger alternator for the domestics I've seen a 120a upgrade which should keep up in theory. We do also have 500 w of solar as well which handles all our general usage over the summer.
Thanks guys,
