I have an issue. Running ESS. I had a single 48/3000 multiplus 2 and this would work great. It would maintain the 50w on the grid and try to put all of the grid connected PV towards battery charging. I had excess PV due to the limitations of the multiplus 2 charging at its max. So to increase th…

These are global settings. 16A would be 8A per system, if you are only seeing 8, it sounds like one is not connected or is misconfigured. The Current sensor is only required on the phase master.

What battery do you have? Did you configured the ESS assistant on both MultiPlus? (“Send to all devices” does NOT work for assistants!)

Did you right-click the master to get into VEConfigure after setting them up with VE.Bus? Also did you set the AC in current to be able to adjust it with remote? [image]

Hi Sean. My system diagram. [image] Cheers. Red..

The location of the CT could be causing issues. How is it configured? Try removing it, so that the grid meter is definitely used.
