Goal Zero Yeti 1400 Lithium, ARB Elements, Boulder 100 Suitcase Panel. Pretty expensive, but happy with the setup and easy to move between rigs if you need. Solid packaging on all 3. The ARB is particularly efficient, though I understand some of the newest fridges out there are starting to edge it out.
Between the ARB and GZ, initially quirky interaction. Connected them using the 12V. The ARB fridge has a voltage sensitive cutoff (seemingly calibrated to a lead acid bat as though you were going to connect directly to a drive battery on your truck; prevents you killing your drive bat). In short, below a certain voltage, the fridge won’t kick on. Problem is that the lithiums reach a low enough voltage (to trigger ARB’s factory default), while still at a fairly high state of charge. (70% if memory serves).
Change the settings on the fridge to low sensitivity and it plays nice down to roughly (40% roughly). That’s been fine for me in practice.
An adapter from Goal Zero apparently solves that issue entirely, but it annoyed the tail off of me to need a $40 adaptor to run a 12V DC fridge from what’s advertised as a 12V DC supply port on the GZ.
In terms of charging, only need maybe 2-3 hours of solid sun to keep the system topped off (when using that fridge without other draw).
Hope that might help anybody interested in the setup.
