I have tried Dynamic ESS node RED flow and on top of my other post regarding settings I have possible issue with battery charging. Not sure if that behaviour is expected or it can be modified, but even when batery is not charged, grid costs are low, there is excess, batery is still in idle state and not charging, but excess is sent back to grid.
My ESS node setting:
current VRM:
NodeRED Dashboard:
Battery capacity is 400Ah (20kWh). although its quite cloudy and rainy today, there is still excess (lower than expected). But it seems that battery SOC is not going higher at all, only lower. This morning Flow was disabled and thats why battery was charged to current level.
I have disabled flow yesterday as in the afternoon it suddenly started to discharge battery into grid even during quite low price. I did some modifications today to configuration values but it didnt helped with idle state.Is it expected? Or is there some modification needed?
