Several years back I installed a Generac whole house generator and my entire house is Insteon which works extremely well. Problem is I have an older Generac 16KW unit and when it starts up in a power failure it causes the lights to mostly go to full bright and I have no control at any switch or through Indigo or through any other means. I literally have to unplug the circuit from the module to turn off the light! Power failures are few and far between so this has not been that big of an issue but now that I have the time, I figure I need to work this out. I assume it is because the generator power is dirty or modified sine wave and this is causing the issue. The Generac units built after 2009 seem to have changed the way they produce power and now have something the call "True Power" which claims the following.
Delivers best-in-class power quality with less than 5% total harmonic distortion for clean, smooth operation of sensitive electronics and appliances.
Everything else in the house works as if I were on the grid (TV's, computer, appliances) with only 1 other exception. A couple of UPS units are clicking all the time which I did try unplugging think they may be to cause of the insteon no communications but to no avail.
Can anyone confirm Insteon works with the newer type Generac generators with clean power? Right now I can get a smoking deal on a new unit and sell my older unit to someone with little cash outlay however this would be a total waste of time/effort/money if the new units do not address the Insteon issue.
