I need help analyzing pros and cons of systems for my scenario. I have a 160 sqft off grid cabin. Only loads to power are lights, composting toilet fan, sink pump, and would like to add a fridge. Maybe a hot water heater eventually but not sure if that's feasible electrically or propane would be better. I have a generator for backup and a south facing roof with 8:12 pitch. We are only out there on the weekends. Typically 2-3 days but would like to plan on having a setup I could grow into remote work capable.
Option 1: Plug and play eco flow delta 2 with extra battery is for sale for $999 right now. That's 2000wH and ready to roll out of the box.
Option 2: 12v all in one MPP with li time 230aH battery. I think this gives me 2760wH (12 V x 230 A)

For option 2, can I leave it hooked up if I'm gone for months at a time? It will freeze over the winter.
Both systems seem like 200-400W of solar would be good?
I plan to wire a 30 A inlet for the generator to plug into and need to figure out how to convert this to 120v for charging AC in on the batteries. And then I want two 120v outlets in the cabin that I would wire to the inverter somehow. Eco flow gives me 1800 W while MPP gives me 1000 W. Is this a big functional difference? Do I need a subpanel?
