I'm fitting out my boat and have bought a 48v Victron Multiplus 8kw Charger Invertor. I went big as I'm looking to reduce my reliance on gas and got fed up with a 3kw invertor and the limitations of it when I want to run a lot of items. I also bought 4 x 205ah 12 volt batteries to satisfy the 48v, which I believe have to be wired in series.
I am told that if I wire in series then I effectively lose the 820ah potential of 4 batteries and would only in effect have the ah of just the one battery, or 205 ah.
Can anyone advise if this is correct and how I would go about accessing the 800+ amp hours I thought I'd got access to? Do I need 16 batteries to achieve 820 ah or can I in fact wire in parallel whilst keeping the invertor happy?
Thanks for any guidance here, I'm out of my depth :)
