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

[Amos Post]

I also have a new (7 month old) PAE system with 2-4448 Inverters (stacked) that we are having some strange issues with.  The most troublesome issue is the new Rheem wall-hung LP instant water heater/boiler is throwing an Error Code 12 which is supposedly a “Flame Failure”.  It’s a brand new installation with new tanks and lines and the gas guys have doubled checked everything.  We are now wondering if it might be related to the power supply.  The other indications that it could be related are flickering lights, a 12V battery charger (AC plug in type) that won’t work off inverter power (but will when plugged into the genny, and I’m seeing a little bit of wondering in the Hz on my simple Exeltech volt meter.  

Magnum recommended a run capacitor on the boiler circuit.  I installed that on Friday and still had the error code come up 4 times over the weekend.

Any thoughts?  

Best,
Amos
