They are expensive. But from a technical point of view, very few people understand (or know how to use) the concept of “Days of Autonomy”. I personally use a 3X factor but if I want to be extra conservative and the application is is critical I use a 4X factor. - Peter Peter T.

Re: [RE-wrenches] Portable Power Centers
I would not go DC for starters. I lived with a DC fridge for years and would not wish that on anyone in the 21st century. Regular Energy Star rated models are very close to the Sunfrost energy numbers, but are much cheaper, are readily available, and can be serviced by regular appliance repair folks. On the module type/ price, we switch to much lower cost 60 cell modules at around 300 watts these days, and use an MPPT controller. We're only using 12 v modules for very, very small systems. As far as small power packages, we've always built are own. Goal Zero is more portable/ backpacking stuff; I have a fold up 5 w Module from Goal zero that can charge a cell phone while camping. They're great for stuff like that, but they're going to be way out of the budget for a permanent mounted larger system. Contact us offline, if you want, we could possibly help put together a low cost package system for this application. Not many solar companies want to mess with sub Kw systems these days, but there certainly is a need, as you've found.

Re: [RE-wrenches] Portable Power Centers
I recently saw a YouTube video that compared 4 or 5 portable power units. You might try a search there.
