Re: Minimum inverter for small refrigerator
Most small fridges are terribly inefficient. On a per cuft basis they are terrible relative to a bigger energy star fridge. I suggest you get a Kill-a-watt and test any fridge you are interested in INCLUDING starting amps.
A couple of suggestions include finding the best fridge that suits your needs in conventional fridge, or alternatively find a good Propane fridge. It is my opinion that while propane fridges are ultimately less cost effective when used full time, the equation fall on the side of the Propane when used occasionally. (week ends, holidays, seasonally)
Full time I wish I had gone with a conventional, but by adding insulation to the case, and fans to the evaporator and condenser they burn only a tiny bit of Propane per month. Just for the record, we run as many as a dozen Propane fridges in remote bush cabins, and when installed and used properly they work very well.
Good Propane fridges can be had quite reasonably from wrecked or used RV's. There are some things to look for in a used fridge, but if you buy carefully you can get a bargain. I am currently using one I bought used for $200 and it has run perfectly for 3 years. I have some that have come free, and a couple I found at the dump!
Please note, being a moderator does not add any weight to my opinions 300 watts Siemens/BP panels,plus a Sun 90,, making ~400. ~30 amps into Rogue MPT-3024, 450 ah of Trojan T-105, Morningstar ts300 inverter, a Tri-Metric meter.a collection of antique generators, plus 2 Honda eu-1000i's (also a BS2512 IX controller) and assorted other stuff!
