I have a very weird problem in my ESS system that I have been struggling with since the install. Some weeks back during a troubleshooting session I stumbled upon a behaviour in VRM that I cannot explain and might have something to do with my problems.
As you can see in the screenshot, one of the phases (the black one) is reporting basically zero consumption - that is absolutely not the case. I do logg input from the ET340 device separately too, and below is what that looks like:
Yellow is corresponding to the black line in the first screenshot, representing the third phase, and the additional blue line is exported power (read from the grid meter).
Around 9PM the black line stars to oscillate, that is when I switched the ESS system over from "Keeping batteries charged" to "Optimized". Then it ran out during the night and started to charge again as the sun came up. After that I turned it back 'off' to "Keep batteries charged" and have kept it there since.
Anyone who has an idea about what could cause this o have seen anything similar in the past?
