So, I like the Jackery and Goal Zero products because some have solar charging ability in addition to being a portable power station. As for wattage, you'll need to do some simple math. Truth is, you'll need to size it specific to your application to not overspend. These get expensive fast, so you really want to buy only what you need. Goal zero has some decent 4000 watt options in the $2k range that will solar charge in 24 hours. See how much power your fridge/freezer draws. Then multiply it by 8 hours. For a factor of safety, add 30% on top. That will be the minimum you'll need.
Sounds like a good unit! What wattage of battery power supply would you recommend?
