I've actually just put a cheap Kings fridge on mine (thanks Santa!).
Bring the nerd I am though, I've also got a Victron Cerbo GX connected up to the MPPT & Smart Shunt, as well as a Ruuvi temperature sensor in the fridge. The fridge itself is connected to the Cerbo via a relay
All this means that I can monitor the batteries and turn fridge on and off remotely. I've written a little program that'll do it automatically too, but just trying things out at this stage.
So far, the hottest it's gotten (while in an insulated cover) is 19?. While it's running, it uses about 1.5A (15-20W), probably would take about 30 mins to cool down to 4?. Because I can choose how and when it's running though, I can be pretty conservative and leave the batteries charging, or if there's loads of sun, just let it run for ages.
At this stage though, I don't have lithium and they're also my start batteries, so I'm being quite conservative and just running it ahead of when I know I'll be on board.
