Has anyone figured out a slick solution for faster battery charging while off shore power? I routinely drop to 60ish percent at anchor since the inverter does almost all the boats AC needs and with a 1600ah agm bank it’s about 8hrs of gen time to recharge using the xantrex 3000 inverter/charger. As far as I know the lifeline L16s will take way more charging amps than the 150, plus at 80 percent the xantrex drops charging rate as it switches to absorption, great if plugged in for long periods but not sure it’s needed during daily use.
I thought about 3 options:
Larger AC bulk charger - hard to wire and play nice with the xantrex, cheapest, requires generator run time.
Large alternator off gen or AC motor - noisy as I’d loose the sound shield, Ac motor would be super noisy given my watermaker sound. Requires generator run time.
Small engine with alternator - complex, another thing to service, But adds redundancy and low fuel usage.
Other than the washing machine, heat pumps (for cooling only) and water maker I don’t need the gen if I did a separate solution.
Has this problem already been solved, and/or am I over thinking it? This was interesting Diesel Battery Charger
