I have been doing some research on generators for longer summer trips.
The key requirement for me was recharging the battery. At least once a summer I go on a 9 day trip in July or August and keeping the battery topped off was a concern. But while I was looking i decided to see if I could also find one that would run the AC and Microwave (not at the same time).
I knew that the smaller hondas were hit or miss and there were some mods to add a start capacitor to the units but then i came across this unit from Westinghouse (WH2000i
I was a bit skeptical due its smaller size engine and lower weight. I figured it was just over rated for marketing. After doing some more digging i came across a few test videos on youtube and they seemed pretty positive.
Well I figured for the price it was a better value than the Honda's out there and I knew westinghouse has some good frame generators and decided to give it a shot. Worst case i had a nice inverter generator that would charge everything and then some.
Well i just got the unit in today. Added oil and some gas and the thing started up on the second pull. Very smooth and easy start.
I hooked up the camper and everything was charging well. At this point I decided to run the deciding test, The AC.
For the first test I kept the generator on Eco mode and just fired up the AC. The fan turned on and then the compressor kicked in. There was a moment of hesitation on the AC unit while the generator fought to ramp up the load but it fought through it and a second later the generator was at full RPM and the AC was running.
Next I shut down the AC and tried the microwave. Same thing. I powered on the microwave and there was a brief moment of hesitation where the light went dim in the microwave before it was at full power and running fine.
At this point I repeated these tests this time with Eco mode off. And as expected both the AC and the Microwave (individually) ran without issue or hesitation as the unit was already at the higher RPM.
I did not test both at the same time as that is clearly beyond the 1800 watt rating of the unit.
Obviously I would turn the Eco mode off if i was planning on using the microwave or turn the AC on to cool off the trailer, but it was nice knowing that albeit with a slight hesitation that if I forgot to flip the Eco switch before using the microwave that it was able to handle the change in load.
Overall for the price i paid, I am VERY happy with the unit. It was a bit lighter than i expected (I was looking at the larger 2000 watt units prior) and is quiet. Under full RPM i was able to hear it from inside the unit when it was near the trailer tongue. But it is a very comfortable sound. A low purr and not distracting or bothersome at all (keep in mind that I am coming from using an open frame generator).
It may not be a Honda or Yamaha, but i would at this point I would call it a solid product. Time will tell if it lasts as well, but i suspect that it will.
Obviously your mileage may vary with the AC. It is my understanding that 1800/2200 watt is right on the fence with the power needed to run these units. But based on my use so far the generator seems to live up to its ratings.
