<p>I see. <br>
</p>
<p>What you say about the frequency shift being slow makes me again
doubt the value of even using it in my application.<br>
</p>
<p>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.<br>

<div>I have a relay on the XW+ Aux and also frequency shift

I also have a DC coupled array feeding the system. <br>

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

I have a small array of 8 - SMA SB240 microinverters
