ust fell into this Solar DIY wormhole. Looking to create a solar “generator” be able to go camping for lets say 3-4 days tops. Would be powering with 2 100w foldable panels. Need to power my laptop for full time 9 hour work day. as well as phone, and lets say possibly a 12V Iceco fridge if necessary. More worried about being able to power a laptop or charge it for the three days without issue as well as the phone to tether wifi. I don’t really have an idea how much capacity I need.
Was originally looking at (4) x 280ah 3.2V LiFePo4 wired into 12v. But then looking at the inverter I would need and just how much power compared to what I’m using it for etc I started to realize its total overkill. So then looked more into 100ah but looking at what commercial “generators” make, 300-500wh seems fine? any advice would be helpful. or if any more specifics are needs I will fill in what I can.
