Help with Battery/Inverter/Alarm NR flow setup

Hi All,

I would like to get some help on this flow setup. I haven't deployed it because I have no experience with NR setup. I did try a while back but this didn't work but since then I've remade the flows.

What I'm trying to achieve:

Using ESS in the background to control the SOC% easy. Then node-red:

  • Charge batteries between set time of the night
    • If battery level is below 10%, inverter mode set to 'ON' for battery charging
    • If battery level is between 10 & 80%, charge at set time (inverter mode set to 'INVERT only') and run off battery any other time
    • If SOC is between 80-100% use battery power
  • If inverters have warning or alarm state switch inverter mode to 'ON'
  • If inverters have OK state switch inverter mode to 'INVERT only


Let me know if you want me to post the code up.

Hello Victron please help us with ESS Phase compensation!

Hi Victron, we are discussing in several threads a nearly similar question without an expert comment by victron-staff:




This main problem of an „symmetrical“ or „balanced“ ESS in a three phase grid-parallel setup is absolutely essential for the German and Austrian market. Please let us know what you think about it! Thank you very much!
