maximum current to the batteries (MPPT Charging). When the battery voltage
reaches the constant voltage set point, the controller will start to operate in constant
charging mode.
b) Constant Charging
When the battery voltage reaches the constant voltage set point, the controller will
start to operate in constant charging mode. The MPPT charging stops during this
process, and the charging current will drop gradually simultaneously. Constant
charging has two stages, namely, equalize charging and boost charging. These two
charging processes are not repeated. Among them, equalized charging starts on the
28th of each month.

Boost Charging
The default duration of the boost charging stage is generally 2 hours. Customers can
adjust the constant time and preset value according to actual needs. The system will
switch to the float charging stage when the duration equals the set value.

Equalize Charging
WARNING
Explosive Risk! Equalizing flooded batteries would produce
explosive gases, so well ventilation of the battery box is
recommended.
CAUTION

Equipment damage!

Equalization may increase battery voltage to the level that
damages sensitive DC loads. Verify that the load's allowable
input voltages are greater than the equalizing charging voltage.

Over-charging and excessive gas precipitation may damage
the battery plates and activate material shedding on them. Too
high an equalized charging or for too long may cause damage.
Please carefully review the specific requirements of the battery
used in the system.
Some battery types benefit from equalizing charging, stirring electrolytes, balancing
battery voltage, and accomplishing chemical reactions. Equalize charging increases
the battery voltage to make it higher than the standard complement voltage, gasifying
the battery electrolyte.
If the controller automatically controls the next charge for equalizing charging, the
equalizing charging time is 120 minutes. Equalize and boost charges are not carried
out constantly in a full charge process to avoid too much gas precipitation or
overheating of the battery.
