CIRCLE WITH A DOT

@MLE_online The documentation is really confusingly organized, but here https://joeyh.name/blog/entry/fridge_0.2/ it says "It ties into the typical offfgrid system of a solar charge controller, battery bank, and photovoltaic panels."

I think they are just software limiting it from consuming energy from the battery in most cases. This would make more sense how the system is able to function being a 1500w inverter connected to a fridge. All the magic is in the controls to limit its consumption, but its using typical charge controller and battery to get a stable DC supply to the inverter.

@MLE_online With enough thermal mass and pulling the fridge temp down to just above freezing it should hold fine. I've gotten thru power outages running a fridge on generator in daytime only before.

The other consideration is the starting current of a typical 120v fridge compressor. An inverter big enough to do it is going to waste a lot of energy and need some amount of battery for the current pulse. The defrost cycle is a consideration as well.

It's probably much more doable starting with a 12v powered RV/Car style fridge, especially now that tiny inverter compressors are a thing.

@MLE_online The fun thing about the really old 18v One+ Ryobi tools like that drill is you can use their modern lithium batteries with them.
