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.

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!
