I have a really small load that Id like to be able to keep up for a long time if my power goes out.
THe load is about 18VA, and the PF is pretty poor, like 0.5, so the wattage is not high.
So Im just curious about approach. Since some power electronics have current minimums and the efficiency of some of the devices is higher at a good amount of load, I dont want to buy too big for runtime and then eat up the stored energy by excess inefficiency in the converter, or perhaps a load that is too small to even be supported properly.
Is this a consideration? THat tiny load is across two separate plugs, FWIW.
