to Float, when to switch back to Bulk, or Storage. And in those various phases they use the configured
parameters in VictronConnect and VEConfigure.
In certain systems, the internal charge algorithm is disabled, and the charger is then working with an
externally controlled charge voltage target.
This guide explains the different possibilities:
Internal
The internal charge algorithm (bulk → absorption → float → re-bulk), and the configured charge
voltages are active.
Inverter/charger indicated charge state: bulk, absorption, float, and-so-forth.
MPPT indicated charge state: bulk, absorption, float and-so-forth. (firmware version v1.42 onwards.
Earlier versions have a bug that make the MPPT say "Ext. Control" when it is only being current
limited; its internal charge algorithm still active.
Inverter/charger (applies to MPPTs only)
The MPPTs internal charge algorithm is disabled; instead it's being controlled by a charge voltage
setpoint coming from the inverter/charger.
MPPT indicated charge state: Ext. control.
Battery
The internal charge algorithm is disabled; and instead, the device is being controlled by the battery.
Inverter/charger indicated charge state: Bulk when in current controlled mode, Absorption when in
voltage controlled mode. Never Float; even though currents might be low / battery might be full.
MPPT indicated charge state: Ext. control.
