[RE-wrenches] Off Grid Optimizers

[jay]

HI Drake,

I was just talking with a colleague the other day about a project he did. 
New Radian, AC coupling, lithium batteries, SB inverters.  Everything is working just as it should with the GT inverters tapering during AC coupling frequency shift mode.


I would say you are fine, and while I can’t say for sure if the Enphase will work that way, they should as they are all designed to the same parameters rule 21. 

I always do recommend a aux relay for backup/shutoff  should there be some kind of issue. 

With the Envoy you’ll be able to see that tapering as well.

Seems like a good option for your application
