A moderate solution

[Zzmeyer]

Looking for a good middle of the road solution. I know more is better often. I have an offer in a 2114 Jeanneau 44.7. Air con but use at slip only. Cruising ground ScCal a western Mexico. Currenttl no reliable no electrical manager or control system. Five months in Mexico thee in SoCal. Have skip when away more than two weeks. Generally rust a couple but frequent cruise. Major energy user air fridge ad freezer, some microwave. Some electric outboard. Usual toys and electronic toys. I’ll measure actual usage on board but what are your recommendations. I motor slightly more than average. High amp alt. How high. Lithium bank how large. Solar, how large. Bias against wind. Am I wrong.
