Are you in Canada by chance? I could only find 19% in the US

No. Gulf coast hurricane alley. Looking forward to not sourcing gas for my generator anymore.

So random question and thoughts in case anyone has thoughts or feedback. Brother and I are building up Ice House. I'm looking to get a battery bank/solar setup. I'd like to avoid the generator if I can but if I have to just to charge things up I will. All that being said any recommendations or thoughts on inverter/setup on how long this would last running some TVs, lights, chargers, etc. I'd like to investigate just going standard 110 small appliance too if I could do it and skip the 12v stuff all together, or at a bare minimum just a 12v light or two.

Am I stupid for wanting/thinking this would be easier? Would 2 of these be enough? Would I need 4 instead? Realistically the amount of juice being pulled is just the lights and TV's running maybe 4-6s a day and over the weekends longer of course.

I guess I lucked out not hesitating.

I bought two of these. I charge them outside with 2 or 3 175W panels, which takes 2-3 days in summer (per battery), but longer outside of summer months because of weather and length of the days. In winter, they have to be warmed up. Charging below freezing will damage the cells (you mentioned Ice House). One battery will power my computer for about 3 days (200-300W) for 6-8 hours using a pure sine inverter. Inverters themselves consume power just sitting at idle (maybe 30W?). So how much you need will depend upon your power draw and whether you leave it sitting idle when it's not in use. Add up the wattage of the things you want to run, multiply by hours of use. Each of these batteries stores about 3.5 kWH of energy, so divide your daily requirement (in kWH, so divide your watts x hours by 1000) into 3 (to allow for losses in the inverter) to get how many days one battery will last. The tricky part is figuring out how much wattage in solar panels you'll need to charge the batteries to keep uo with your consumption. I use a charge controller with Anderson connectors to charge mine because I physically take them outside to charge. You'll more likely want to rig up a system where you don't need to move them around, but make sure they don't go below freezing when charging. That's a long, rambling answer, but I think I hit the high points.
