1100 Watts of Solar Power = 350 Amp hours per day on average good day
SuperWind = 96 Amp hours on average good day
2 high output 165AMP alternators for total of 2 hours or 1 hour each = 265 Amp Hours per day

So about 750 Amp hours production per day. More or less engine time.

Induction Cooktop 1 hour = 200 Amp hours
Refer/Freezer high efficacy = 350 Amp hours
Watermaker, oven (Panasonic 4 way convection/microwave), electronics electric grill = 150 Amp hours

So about 700 Amp hours of usage per day and I bank 50 amps.

2 Victron Inverter/Chargers for 6,000 Watt but redundant capacity.
Isolation Transformer

Up to an additional 250 Amp hours used while cruising that would require running engine for about two more hours.

No genset.
760 Amp LifePo Genasun, might add another 380Amp Genasun

It's crazy but I still like the idea of no propane and all electric except for main engines.

On a good day, we make power even maybe on a crossing. On a bad day, run engines for a total of 4 hours - ouch.

When I write it down, I say hummmm. Anybody living like this and happy.
You have LiFePO4 a battery bank so its possible, but the above power usage from a Lead Acid bank man work on paper....but is fantasy in the real world of off the grid living. I can run my 30GPH water maker (1100w) and my hot water heater (1500w) from my LiFePO4 battery bank with 1300w of solar and KISS wind gen.
