By default, boost charging generally lasts for 2h, but users can adjust
preset values of duration and boost voltage point according to the actual
needs. When the duration reaches the set value, the system will then
switch to floating charging.
Equalizing charging

Warning: Risk of explosion!
In equalizing charging, an open lead-acid battery can produce explosive
gas, therefore the battery chamber shall have good ventilation conditions.
!
Note: risk of equipment damage!
Equalizing charging may raise the battery voltage to a level that may cause
damage to sensitive DC loads. Check and make sure that allowable input
voltages of all the loads in the system are greater than the set value for
battery equalizing charging.
!
Note: risk of equipment damage!
Overcharge or too much gas generated may damage battery plates and
cause active material on the battery plates to scale off. Equalizing charging
to an excessively high level or for too long a period may cause damage.
Read carefully the actual requirements of the battery deployed in the
system.
Some types of batteries benefit from regular equalizing charging which can
stir the electrolyte, balance the battery voltage and finish the
electrochemical reaction. Equalizing charging raises the battery voltage to
a higher level than the standard supply voltage and gasifies the battery
electrolyte. If the controller then automatically steers the battery into
equalizing charging, the charging duration is 120 mins (default). In order to
avoid too much generated gas or battery overheating, equalizing charging
and boosting charging won't repeat in one complete charging cycle.
Note:
1) When due to the installation environment or working loads, the system
can't continuously stabilize the battery voltage to a constant level, the
controller will initiate a timing process, and 3 hours after the battery voltage
