At 9K feet that gen is doing all it can to run the MW.

Plug in a volt meter and tell us what you see. With TRUE SINE Inverter generators you may or may not be able to use a Kill-a-Watt (there is debate on this I have a Kill-a-watt plugged into a true-sine-wave inverter powered line no problems. others have reported problems)

You can also use an analog volt meter I have 2 of those that plug in too one was free (won a drawing) the other I paid for (Too much) at Camping world.

The one I like best is by MFJ enterprises and is a plug in meter with pass through (that's my favorite analog) you can google MFJ plug in voltmeter.


Home is where I park it.

My friends rv has an electrical management system. Even when nothing is turned on, but plugged into shore power, his management system reads between 3amps and 7 amps. Im assuming this is his charging system because nothing else is on. If that is the case, and you have not had the generator running, the batteries are not completely charged. Therefore, when you start the genny, the charging system is going online to recharge your batteries. If my friends rv is any yardstick, this is between 400, and almost 800 watts that the charger is taking. This is between a quarter, and half of what your genny is putting out. Turn off the charger, run a cord straight to the microwave, or get a bigger genny. As stated, higher altitude steals a portion of the power as well.

That generator is rated at 1600W continuous. That is about 13A @ 120VAC. That microwave is probably pushing the capacity of that generator.

The EF2400iSHC would be much better at that task.

IMHO, all of the "one hand luggable" generators are "missing the mark" The should be 2800W/2400W (true 20A continuous) output. The Westinghouse iGen 2500 is the closest.

Yes it is, close to running the air.

At 9000' it's not even worth trying IMO. A commonly used rule of thumb is 10% output loss for every 3000' of altitude. With that, the 1600 VA continuous rating would be 1020 VA, and the 2000 VA surge rating would be 1400 VA. A 1000 watt microwave will bust even the surge rating.

I agree with the others. At 9,000' you need two of the generators paralleled. Even then, you are not over powering your RV.

Not so long ago I bought a new Yamaha EF2000iSv2 generator. Maybe someone has already had an experience with this gen and can suggest how many appliances can I run with it?
