I see.
What you say about the frequency shift being slow makes me again doubt
the value of even using it in my application.
I have a controller that can regulate the AC dump load. That same
controller has a high limit switch which I could use to cut the AC feed
to the GT inverters. But then both functions are in the same device. On
the other hand, it is a very reliable device so....perhaps sufficient.

I have a relay on the XW+ Aux and also frequency shift which is
usually slower, so the relay usually cuts out first. I also have a DC
coupled array feeding the system.

Yes an elite group within an elite group.
So the SB240 does not have frequency shift /wattage control. How
are you implementing charge control in stand alone mode?

Wow! Someone else with SMA SB240's, I have 12 of them that I've
AC coupled to an XW+5548. They are very solid performers.

Hello,
I have a small array of 8 - SMA SB240 microinverters on the
roof. Peak
power out of the array has never exceeded 1800 W.
I am adding a Magnum MS-PAE 4448 with a 315 AH flooded Lead
Calcium
battery bank.
Cheers
