Hello,
I am running my own control loop on top of ESS 3 mode with my 3 phase setup. I usually use “passthru” mode when grid energy is cheap. I trigger passthru on MP by “stop sending” updates to AC setpoints - after 60 seconds passthru is triggered and inverters stop inverting.
The problem I noticed today is, that when the system is in the passthrough during the day, the sideffect is that MPPT stop charging batteries. I want state when MPPTs are charging battery while MultiPlusses are consuming as little as possible and load is being powered by grid unless grid fails. I would love to use volatile registers because this state is triggered several times a day - do not want to burn the flash.
Do anyone know how to trigger state, when MPPTs are charging but MPs are stading by waiting for grid to go down? Only way I figured out was just to copy consmpution to to AC setpoints but this is not as elegant solution as I could imagine.
