I still recommend using a relay triggered from the Aux for AC coupling, it
works reliably and quickly.

Jay,
XW+ and XWpro have so many adjustments for AC coupling that I wish they
would just make an offgrid firmware version that would get rid of all the
grid requirements. I tested this on XW pro and it took about 8 seconds.
However, as Kienan remarked it would also depend on charge rate from both
Jay,
It waits 50 seconds to even start to try to shift the frequency. I don’t know
how long it takes to get up to get to 64 HZ. I heard somebody say that they
thought that the 50 second delay should be adjustable, but I could not find a
way to adjust it. I have not had a chance to talk to
HI All,
I’ve got a project using lithium batteries and a big hydro.
4kw hydro
6.8kw schneider
off grid
AC coupled hydro
The plan is to use a combination of ways to keep from overcharging the
batteries.
1. PWM diversion control load. If this doesn’t keep up then we go to #2
2. AC couple HZ
