I'm researching portable backup generators for my house. I installed a manual transfer switch box with a remote power input box. I'm looking at the Yamaha and Honda models in the 3-5K watt range. Do I need an inverter generator to run my computer and flat screen TV or will some of the non-inverter generators do the job? Of course I'll be running other items too, like the refrig and heater blower but I assume any generator will power these. Anybody run their sensitive electronics with a non-inverter generator?
