Dvcc For Systems With The Ess Assistant - Victron energy Color Control GX Manual

8.6. DVCC for systems with the ESS Assistant

• The ESS Keep batteries charged mode works properly. It does not without DVCC.
• A fixed solar offset of 0.4V is used instead of a variable 2V. (values for 48V systems, divide by 4 for 12V). Note that this solar
offset is only applied when ESS-mode is set to Optimized in combination with the Feed-in excess solar charger power-setting
enabled, or when ESS-mode is set to Keep batteries charged.
• Add Auto-recharge feature for the ESS Modes Optimized and Optimized (with BatteryLife). The system will automatically
recharge the battery (from the grid) when the SOC drops 5% or more below the value of 'Minimum SOC' in the ESS menu.
Recharge stops when it reaches the Minimum SOC.
• ESS improved state display: In addition to the charger states (Bulk/Absorption/Float),
additional Discharging and Sustain modes were added. In addition it also shows reasons for the state it is in:
• #1: Low SOC: discharge disabled
• #2: BatteryLife is active
• #3: Charging disabled by BMS
• #4: Discharging disabled by BMS
• #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.
