[RE-wrenches] Enphase IQ and Schneider XW AC Coupling Performance

[Dave Angelini Offgrid Solar]

The old gray box XW's never really were designed for AC coupling. It
could be made to work with a xantrex grid inverter but most were told to
upgrade to the white box XW+ and XWpro.  

I doubt anyone would notice the
XW+ or pro when it shifts a couple hz to protect the battery after it is
charged.

inverters to our battery backup system at home (Schneider XW4024 with 370AH
battery bank). The result was something that I would never want to
duplicate for a customer owing mainly to the flickering of lights during
the daytime when the XW is shifting frequency.    I'm curious if the newer
Enphase IQ and Schneider XW equipment behave better in an AC coupling
scenario. Can the newer Schneider inverters cue the micros to taper their
output and are there any downsides to power quality that the customer might
notice during an outage?    Hoping to glean some real-world observations.
Many thanks in advance!!   -Matt
