Dave has been cooking so many interesting fermented dishes for us all, and I am interested in adding some new ferments to my repertoire in preparation for living at Allerton Abbey without refrigeration.

There was nothing on the market at that time except the GoalZero ($$$+++). Or there was make-your-own. Now, the Li batteries are getting both better and cheaper, but still cannot meet the expectations of users of an on-grid home, or of a 5kW RV gas generator. So there are now lots of products, but no killer-for-all-use-cases products.
Jen's report that they don't have time to work this project fits my experience, too. 3 years ago, I decided to build my own, started buying parts, and then never made a finished unit (though we did use the parts in a bread-board kind of way). At these price points, even just deciding on your requirements and then shopping becomes rather time consuming and tiring.
So far in the thread, we have:
EGO PST3041 - $1699 for ~1120 watt-hour ~= 1.51 $/wh. Can do BIG power tools well, if you want that. 7h (?) full charge from grid power (could get that down to 40 min with extra hardware). Can carry batteries to recharge separate from unit. 50 lbs to carry whole unit. Solar recharge not supported. Respected brand.
MaxOak - $1250/1500 wh ~= 0.83 $/wh. Nice capacity. Solar ready. 40 lbs to carry. 10 hours full charge from grid power. Less-known brand--12 month warranty claimed. (Why is the PD output only 45w? near-miss-killer-feature, IMHO.)
Jackery Explorer 500 - $399/518 wh ~= 0.77 $/wh. Minimal capacity for stated use (5h of laptop). Solar ready. 13 lbs to carry. 8 hours full charge from grid power. Respected brand.
Another option would be to buy a minimum number of replacement Lead Acid batteries for the Voltzwagon for now. (You could still fix the whole existing bank later.) (Edit: Nevermind--the numbers probably don't work out on this. Looks like 4x6v in 2 parallel stacks, with extra sensing wires. I was imagining putting 2x12v temporarily, but doesn't look easy. You'd only do this if the new batteries were lying around "free" or something.)
Or Jen implied fixing the existing Voltzwagon bank. I assume this would involve dragging all those LA batteries (8?) to town or basecamp for reconditioning. Labor intensive.
I don't think much progress will happen until Josiah has time to think about how he wants to do this project. But it is fun to make gift lists at Santa-time. (aka, I was procrastinating doing something else.) :)
Hope this comparison helps you, Josiah and Jen, with the off-grid-office project. Obviously an interest of mine, as well.

An 18"/45 cm ditch blade from FUX would be real nice.
