Hi valhalla,
Ty for pointing that out.
Sorry I was not clear--these numbers are from my RV--but I think that most units have similar draws.
So far as I am aware the only microwave that uses inverter technology to allow lower power levels is Panasonic. The others (and mine) merely pulse on and off to slow the cooking process.
I "get around" brief over loads by using the "load support" feature on my hybrid inverter. But be aware load support is NOT voltage support, so it still behooves the end user to monitor what is going on.

Hi,
The microwave draws 1561 watts and the water heater 1400. Adding in the fridge is another 325 watts. One would have to rely on the water heater and fridge being in the off part of their duty cycle, or there might be quite a bit of voltage drop.
The advantage is the ability to run the roof air conditioner.valhalla360 wrote:
Reality, is you can run the microwave, TV & fridge simultaneously. Possibly the water heater but that's pushing it a bit.
That's awfully specific...where did he list the microwave model? Some microwaves go that high but I've also seen smaller 600-800w models and you can use lower power settings.
But as I said, running microwave and water-heater simultaneously gets iffy...even at 800 + 1400 if the charger kicks on at 50amp/12v...you are pushing the limits of a 3000w generator...which is likely rated for a lower amount in continuous duty.
3000w is plenty for air/con. We run on a 2600w yamaha. (no, not with microwave and hot water heater but TV, fridge and lights we've never had a problem).
