Jason, You may want XW pro. It is not much more than XW+ and will have a
better support for what you want in your microgrid. It also has twice the
warranty over xw+.

"know" when the ATS switches to inverter power. I'm thinking I need to use
an AUX relay or a series of relays to produce the desired result. I don't
think it will be necessary when going from solar to generator in this case,
but maybe. I guess the question is how to activate the time delay any time
the ATS switches over. That would be the easiest solution maybe. I'm
probably looking at a quad Conext XW+ system here. Even at over 100A @ 240V
continuous rating I'm anticipating some startup issues with all those
motors (I forgot to mention well and pressure pumps also!) Jason

In an off-grid situation I'm looking for a strategy to manage
transfer from generator power to inverter power because I have a lot of
high startup load appliances planned for a system. Think 8
mini-refrigerators, one sub-z large refrigerator, and an under-cabinet ice
maker, not to mention air conditioning. I would like to start these loads
in stages if they all call to start up immediately upon system startup or
during ATS switch over. Any ideas? I guess while I'm on the subject I
should ask about my eye-roll, keep-me-up-a-night, giving-me-heartburn
problem with this ice maker. It's going to be outdoors in Florida and they
expect it to make 25-50 pounds of ice per day. I am finding it really hard
to estimate energy use for this appliance. Any ideas (other than the
obvious "don't do it" answer)? Jason Szumlanski Florida Solar Design
