Also, do you know how to post photos in an online forum? It's pretty easy......
Not sure where that comment came from since I have never had a problem not a "dirty power" and yes, I know how to photos. Actually, in this thread I linked to another members photo in another thread, now apparently gone or moved which had really dirty power. I don't know why the image disappeared from this topic unless the other thread was changed. It wasn't my photo so I linked to it.
Here is the other members image, since I saved it
My main generator(wired into the my multiple circuit changeover box (so I can shed loads) is a high end brussless Yamaha EF5200! I have tried a cheap ETQ 1800 watt brushed generator and a Statpower PROsine 1800 inverter as well as tests. All were in good condition and had clean output.
Actually, for unattended operation. the PROsine 1800 is ideal! Should the batteries run dead and fire go out, that inverter requires manual reset after low voltage shutdown. Should the power be restored, the stove doesn't dump unburned coal. Actually it would be nice if the stove didn't feed after a "fire out" situation.
The only problem I have yet encountered is I try to operate too many/heavy switching power supplies at one time off a generator. Computers, the 60A charger for my battery bank... Many modern electronics have a diode bridge - capacitor input circuit which puts the maximum current at the voltage peak, thus flattening the voltage peak. This didn't bother the Coal-Trol since I still have a smooth slope but does upset one of my computer power two APC UPS's with boost/buck circuits.
