When the duration times reaches the preset value, the system enters floating
charging stage.
☆Equalizing Charging
Warning: explosion!
Balance opening lead-acid batteries may produce explosive gas, and cabins of
the batteries must be well ventilated.
Attention: equipment damage
！
Balance can push up battery voltage to a level that may damage sensitive DC
load. Verification is required to ensure that the allowed input voltage of all system loads
is higher than the set value of equalizing charging for batteries.
Attention: equipment damage
！
Overcharging or too much gas evolution may damage battery plates and cause
active materials on battery plates to fall off. Damages may be caused if equalizing
charging voltage is too high or equalizing charging lasts too long. You are advised to
carefully read the specific requirements on batteries used in the system.
Some types of batteries benefit from regular equalizing charging, which can stir
up electrolyte, equalizing battery voltage, and complete chemical reaction. Equalizing
charging boosts battery voltage to a level higher than standard complement voltage,
resulting in gasification of battery electrolyte. If it is detected that the solar charge
controller automatically controls the next process to perform equalizing charging,
equalizing charging duration will be 120 minutes (default). Equalizing charging and
boost charging are not repeated in one full charge process. This is to avoid too much gas
evolution or battery overheating.
Attention:
When the system cannot maintain battery voltage steadily at constant voltage
