Calculating amp hours

First time poster. at the planning stage of van build. Trying to calculate my projected power use to plan my solar needs. I plan on using a propane fridge which of course will have a control board. Any idea approximately how much power such a control board will need.


Should be in sales specifications of the panel you are purchasing and the UL sticker on the panel. if not call the mfg. If you already have it a clamp style amp meter. Harbor Freight has nice inexpensive ones, come in handy. Should be minimal.

Thanks for the reply. As I said, I am only at the planning stage so have not yet purchased a fridge. Trying to get a feel for my electric needs to get a feel for how much solar I will need.
