My biggest issue is size and hook up between the two types. I don't care about the price. I have limited options where to mount it, and then decide the wiring to the batteries, the converter, the transfer relay and the outlet to the kitchen counter.
Based on size and controls, I like the modified sine wave. I don't think it matters with the coffee maker. It's the SMART flat screens that might have an issue. I guess I should do a test, and see how they work on both inverters, before making a final decision.
