I have a little dorm fridge in my outdoor kitchen (no idea on brand, but it's something like this- random dorm fridge on Amazon
). While we are going down the road, this thing loses heat like my daughter loses sunglasses: quickly and often.
I'm only running a single battery in my setup - a Trojan TMH27
. My thought is to install a large-ish pure sign wave inverter
. And then install a 120v outlet off of the inverter back in the outdoor kitchen. When we have longer driving days, I'd switch the fridge to run off of the invertered outlet.
My concern is- I know there is some charging of the battery from the TV. I don't know how much. Nor do I know if it is enough to overcome the draw from this dorm fridge (with the inverter).
It's not incredibly often, but we do fairly regularly stop for overnight stops without hookups. I'd like to make sure that my battery isn't being depleted during a day of driving and then be unable to support our overnight power needs (generally just my sleep machine and occasionally the furnace).
Being able to push some charge into it over a day of driving would be ideal (while it's SUPER RARE, we do sometimes do back to back overnights without hookups).
Does anyone know if this idea will work?
