Peter - I would contact Faisal at GetChargedUp, they've been doing great things with mobile power for PR<https://getchargedup.net/empower-emergency/building-a-solar-trailer/>, and their based in CA, and they know what they're doing.

Scott Sklar at The Stella Group<http://www.thestellagroupltd.com/> has built some very robust mobile solutions for the US military.

A few other options:

Every one of these I've seen so far....dating back over 10 years....drastically undersizes the battery bank, I assume because that's the expensive part.

I recently saw a YouTube video that compared 4 or 5 portable power units. You might try a search there.

We are working with Turning Point Foundation a 501(c)3 to provide off-grid power for their River Haven project which is providing transitional housing for homeless folks in the Ventura CA area.

The site is truly off-grid and currently uses propane to power three refrigerators and cook stoves. There is no space heating for the single occupancy rooms as of yet. But that’s another problem.

We are looking to specify DC refrigerators and PV-powered battery storage for the River Haven project. We are looking at the Goal Zero Yeti-3000 system (3000 Whr, 500 full discharge cycles, to 80% residual capacity) at a sale price of $2,400 but are finding the extra cost of their PV modules quite steep. And looking at other 36-cell (12 volt) modules, I can’t find anything for less than $1.10/W.

Since Goal Zero is looking at the recreational market, I thought that there might be o ther companies with comparable product offerings that are focusing on other markets like developing countries.

Any advice would be appreciated and you may contact us off-line.
