Thanks for this info. I just purchased a CyberPower CP1500 (like yours) but I just need it to keep my pellet stove running long enough (when power goes out) so I can shut it down before it starts smoking . If the power stays out I have a generator to switch to. Thanks! My pellet stove is a Lopi Pioneer 115 volts 3.6 amps, 60 Hz Watts during start up 400 (approx) watts during operation 180 (approx)
FYI - harman stoves require the Modified sine wave to tell the electronics to initiate a shutdown (pulse combustion blower). If you use a pure sine wave, stove will run fine. However, if power is lost to the stove, smoke could backup into the room.
I would never run like this, the reason I did it was 1) if I smoke the board I cam fix it, 2) people are giving incorrect advise in the forums, and later the same folks are looking for board repairs, I would rather the stove stop dead and smoke out then have a issue where you think everything is fine, but your cheap ups isn't helping you. Ferro resonant transformers have no direct line/load connection, the magnetic field would act as a softer power drop, versus a hard line stop.
Although they recommend pure sine wave, I'm successfully running on a preditor 9000 and also a Chicago electric 7000 with no troubles, any inverter style over 2kw should be fine I say over 2k since I've only tested smaller units with an older 1200w 2 stroke tailgater and it would not run, a 3500 should
Soon after these 2 tests the UPS failed completely with no output power, I assume those transistors couldn't handle the test, the transformer is most likely OK but I won't know for sure until I tear it down. What you cannot hear in the video is the complete stop of the exhaust blower 5 or 10 seconds after the inverter kicked on, also this is the second test the first line voltages were dead on 120V for whatever reason the second test lost 3v through the unit, line voltage was again 120 once removed and back to normal supply voltage.

So would you recommend just using a portable generator to power the stove if you loose power?

also anything but a pure sine wave may damage any electronics, including your circuitboard, which costs may be 400 or more dollars
The frequency stayed a solid 60hz (small display lower number)
