• Boost Charging
The Boost stage default time is 2 hours, user can adjust the time and value of
boost voltage according to requirements.
The stage is used to prevent heating and excessive battery gassing.
• Equalize Charging
WARNING: Explosive Risk!
Equalizing flooded cell battery can produce explosive gases, so a
well-ventilated battery box is recommended.
CAUTION: Equipment Damage!
Equalization may increase battery voltage to a level that
damages connected equipment. Verify that all connected
equipment can tolerate a DC input voltage at least 11% greater
than the equalizing charging voltage.
CAUTION: Equipment Damage!
Too high an equalizing charge or for too long may cause
damage. Over-charging and excessive gas production may
damage the battery plates and cause them to shed material.
Please carefully review the specific requirements of the battery
used in the system.
Some types of batteries benefit from equalizing charge on a regular basis, which
is able to re-mix the electrolyte and balance the battery voltage. Equalizing is
done by increasing the battery voltage higher than the standard float voltage,
which produces gas bubbles from the battery electrolyte, causing the liquid to
re-circulate.
The controller will equalize the battery on 28th of each month. The standard
equalization period is 0~180 minutes. If the equalization isn’t accomplished the
first time, the equalization recharge time will be accumulated until the set time is
finished.
NOTE:
1. If, due to the influence of ambient conditions or variations in load, the battery voltage
can’t remain at the equalize voltage at the programmed time, controller will
accumulate and calculate the time of constant voltage working. When the
accumulated time reaches 3 hours, the charging mode will turn to Float Charging.
2. If the controller time is not altered, the controller will equalize charge
battery once every month following its on-board clock time.
