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.

So the issue I have with the above is a conflict of rules. I.e.

If there is an overload, the inverter will trigger ON (which is correct) but then the SOC% flow will trigger changing the inverter back to INVERT.


I can't figure out how to delay or link the flows so the overload situation has first priority then once overload is ok, reverts back to the SOC% flow.
