DVCC charge limit

Yea, I have read the setup guide several times, but I cant get it working. Clearly I am missing a step some where. As soon as soon I set the software limit in the dynamic power to zero the Fronius inverter drops to Zero. The IP in a reserved IP for that address by the router. It always gets the same address. Screen shots below of the only two pages I can find to set …..that said the documentation always refers to ESS, I dont have an ESS system as I am offgrid, and as such ESS is not enabled.
