Hi, on my boat I have a 12V LFP and a 24V LFP batteries.

I wonder if it is possible to keep them charged with one single 200W (29V) solar panel, and what equipment would be needed.

Thanks

Hi,

long story short: you will need a DC-DC charger.

Charge one battery with solar, and charge the other battery from the first battery with a DC-DC charger.

Best Regards.
