1. Charge voltage limit (CVL): the maximum charge voltage that the battery currently accepts.
2. Charge current limit (CCL): the maximum charge current requested by the battery.
3. Discharge current limit (DCL): the maximum discharge current as requested by the battery.
For all three parameters, some types of batteries transmit dynamic values. For example they
determine the maximum charge voltage based on cell voltages, state of charge, or for example
temperature. Other makes and brands use a fixed value.
Here is the page in the menus showing the parameters:
For such batteries, there is no need to wire allow-to-charge and allow-to-discharge connections to the
AUX inputs on a Multi or a Quattro.
When inverting, ie in Island mode, Multis and Quattros will shut down when the max discharge current
is zero. They will automatically start again as soon as either AC mains returns, or when the BMS
increases the max discharge current again.
See previous chapter, "Limit charge current", the user setting, for details about how the Maximum
charge current is used, how it prioritises solar and more.
All above means that setting up charge voltages or charge profiles in VEConfigure or VictronConnect
is not necessary, and will also have no effect. The Multis, Quattros and MPPT Solar Chargers will
charge with the voltage as received via CAN-bus from the battery.
4.6 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
