When the algorithm needs tuning

[Andy]

This one hit an edge case. Oh it hurt my eyes when I saw it. I was trying to force discharge the battery into the car. Most of it happening whilst I was still in bed so I only saw it later.

Did the battery voltage drop to a protection voltage level where your battery inverter decided to switch from forced discharge to force charge for a while, until the voltage had recovered then go back into forced discharge for a short time before going back into protection mode, etc, etc, etc...........

Been there myself , lesson learned.
