ESS battery state

Hi,

where do I find a description of the different battery states of ESS shown at the VRM "ESS battery life state"?

https://github.com/victronenergy/node-red-contrib-victron/blob/master/src/services/services.json shows that there are the following states:

"0": "Unused, BL disabled",

"1": "Restarting",

"2": "Self-consumption",

"3": "Self-consumption",

"4": "Self-consumption",

"5": "Discharge disabled",

"6": "Force charge",

"7": "Sustain",

"8": "Low Soc Recharge",

"9": "Keep batteries charged",

"10": "BL Disabled",

"11": "BL Disabled (Low SoC)",

"12": "BL Disabled (Low SOC recharge)"


What do they mean?

My system is normally at "BL Disabled" when battery is charged and "BL disabled (low SoC" when SOC ist low.

What does "BL disabled" mean?

You only really need to concern yourself with the high-level states which are documented here and are displayed on the VRM dashboard.

  • #1: SOC is low

  • #2: BatteryLife is active

  • #3: BMS disabled charging

  • #4: BMS disabled discharge

  • #5: Slow Charge in progress (part of BatteryLife, see above)

  • #6: User configured a charge limit of zero.

  • #7: User configured a discharge limit of zero.
