Interesting. This weekend I was servicing the genny and started paying attention to the gauges. Genny cranked and running at idle. 0ish KW. Refrigerator running.
Added the battery charger. Maybe 1 KW. Add the AC (this shocked me no pun) the needle popped then settled at 4KW. Thought it would be more. Turned the thermostat way down, she's blowing cold. No waver. So add the microwave. NOW we bust 11KW. Next hit the biggie -- electric stove eye -- hit 20 KW instantly. So what I learned is that my little 3.5 Nextgen can easily handle my average loads. That's good news!
