I would not suggest it without some fossil
fuel power source. There are a lot of days the sun doesn't shine (enough) and it is really obvious when you are reliant on solar for cooking and can cause discord on board. We have a family of 6 onboard with 1800w solar and 1260ah
lithium and an all electric galley. We run the genset frequently, sometimes twice a week but if it is 3 or 4 days without sun it is daily. Also, your cruising grounds may change. We have been in
Maine for 5 weeks. We run the genset a lot more up here than in the
Bahamas. We are looking at ditching the genset but would only do so if we went with high amp alternators on the yanmars and an additional 600ah on the bank. Just a rough estimate of what I think it would take for us to part ways with the genny given we cook at least tice a day on the induction and in the electric oven. When they are both on we pull all of 3500w on our 12v system and it will soak some battery quickly. Not to mention there is a huge
project time and material cost investment in supporting that level of demand. We added a second set of 4/0 main battery
cables,
inverter size increase, increased size DC cabling between inverter > breakout panel > main house panel, AC
wiring increase to the galley, breaker size increases on the three breakers supporting the galley to name things off the top of my
head, and there are more I have forgotten about. But we were very happy to leave the force10 in our wake so there's that. I would design the system on paper, remind yourself it can go days without 'enough' sun almost anywhere and make sure you are ready for not being able to use heat in your cooking.
