Hello to all,
Our Older Maramu has 4 x 6V flooded deep cycle 190 ah batteries (total 380 ah) manufactured by a company in Venezuela. They are 5 years old and I think are at the end of their life cycle right now. We have 400W of Kyocera solar panels and one new Air X wind generator on the mizzen with a maximum output of 400W, which works quite well in the Caribbean.
The biggest constant draw onboard is a 6 cu ft Isotherm refrigerator and one 3 cu ft Frigoboat freezer. The lighting is all LED. I believe the stereo, the fresh water pump and the anchor windlass are occasional loads that are handled well by the system.
