I have a 3 phase system with 3 MultiPlus inverters. I use the assistants to manage the programmable relays for ACOut 2.
The ACOut relay is on when it is above a % SOC or when AC1 is available for 60 seconds. This assumes that when there is grid the ESS will maintain a minimum SOC for the battery. If grid fails then the heay loads (on ACOut 2) will be turned off and the battery will support the critical loads during the night till the sun comes up and recharges the battery again. This setting is programmed for each of the 3 phases.
The challenge is now that when one of the grid phases fails, still 2 phases see AC1 coming in. Those phases will continue to allow ACOut 2 to be on and draining the battery faster. Despite that my Color Control does not see grid coming in. As such the battery will not be charged to keep a minimum SOC and the battery will not make it through the night will all the issues that come with it.
Is there a way on how I can solve this issue that I allow ACOut 2 to be on when all 3 phases (grid) are working (and will charge the battery) and not only looking in each MP at their respective phase?
Many thanks for your help. (I will post a picture of the Assistent settings when the platform allows uploading again)
