[RE-wrenches] PAE series surge capacity/ power factor ?

Hi Jeremy,

Do you recall my email from May 28, 2021? I explained our experience and solution. I have attached it below for reference.

Hello Jeremy,

For more than a decade we have been aware of this issue wit Magnum Energy inverters. This primarily happened with the washer brand Splendide but other motors run by electronic controllers have caused the issue as well.  

When the washer is powered by Magnum inverters, the AC waveform becomes very distorted. You can view this on a scope as in the attached image. When you try to power other complex loads at the same time, the inverter can’t sufficiently emulate a sine wave.

We found a simple solution. Install a high frequency inverter for the washer only. A 600W GoPower (made by Cotek) inverter has worked for us. They are cheap but well made with great support.

I know it’s common to have some dimming of the lights when a well pump or other large load kicks on, but has anyone ran across a solution to alleviate the problem or boost up the voltage / condition it, in any way ?
