voltage (see table). This absorption time estimation can be
incorrect if there is an additional charge source (eg alternator)
or load on the batteries.
This is an inherent issue in the default algorithm. However, in
most cases it is still better than a fixed absorption time
regardless of other charge sources or battery state.
It is possible to override the default absorption time algorithm
by setting a fixed absorption time when programming the solar
charge controller. Be aware this can result in overcharging your
batteries. Please see your battery manufacturer for
recommended settings.
4. Absorption time determined by tail current
In some applications it may be preferable to terminate
absorption time based on tail current only. This can be
achieved by increasing the default absorption time multiplier.
(warning: the tail current of lead-acid batteries does not
decrease to zero when the batteries are fully charged, and this
"remaining" tail current can increase substantially when the
batteries age)
Default setting, LiFePO4 batteries
LiFePO4 batteries do not need to be fully charged to prevent
premature failure.
The default absorption voltage setting is 14,2V (28,4V).
And the default absorption time setting is 2 hours.
Default float setting: 13,2V (26,4V).
These settings are adjustable.
Reset of the charge algorithm:
The default setting for restarting the charge cycle is
Vbatt < (Vfloat – 0,4V) for lead-acid, and Vbatt < (Vfloat – 0,1V)
for LiFePO4 batteries, during 1 minute.
(values for 12V batteries, multiply by two for 24V)

3.8 Automatic equalization

Automatic equalization is default set to 'OFF'. With the Victron
Connect app (see sect 1.12) this setting can be configured with a
number between 1 (every day) and 250 (once every 250 days).
When automatic equalization is active, the absorption charge will
be followed by a voltage limited constant current period. The
current is limited to 8% or 25% of the bulk current (see table in
