ATTENTION: Dégât sur l'équipement!
L'égalisation peut augmenter la tension de la batterie jusqu'à un
niveau nuisible pour les charges CC sensibles. Vérifiez que la tension
d'entrée autorisées de toutes les charges disponibles sont
supérieures à 11% à la tension du point d'installation de chargement
d'égalisation.
ATTENTION: Dégât sur l'équipement!
Un chargement excessif et une précipitation de gaz peut
endommager les plaques de la batterie et la formation de matières
actives dessus. Un chargement trop fort ou une égalisation prolongée
peut causer des dégâts. Inspectez soigneusement les conditions
spécifiques de la batterie utilisée dans le système.
Some types of batteries benefit from equalizing charge on a regular basis, which is
able to stir electrolyte, balance battery voltage and accomplish chemical reaction.
Equalizing charge increases battery voltage, higher than the standard complement
voltage, which gasifies the battery electrolyte.
The controller will equalize the battery on the 28th each month. The constant
equalization period is 0~180 minutes. If the equalization isn‘t accomplished in
one-time, the equalization recharge time will be accumulated until the set time is
finished. Equalize charge and boost charge are not carried out constantly in a full
charge process to avoid too much gas precipitation or overheating of battery.
NOTE:
1) Due to the influence of ambient circumstance or load working, the battery
voltage can’t be steady in constant voltage, controller will accumulate and
calculate the time of constant voltage working. When the accumulated time
reach to 3 hours, the charging mode will turn to Float Charging.
2) If the controller time is not adjusted, the controller will equalize charge
battery once every month following the inner time.
C) Float Charging
After the Constant voltage stage, the controller will reduce charging current to Float
Voltage setpoint. This stage will have no more chemical reactions and all the charge
current transforms into heat and gas at this time. Then the controller reduces the
voltage to the floating stage, charging with a smaller voltage and current. It will
reduce the temperature of the battery and prevent the gassing and charging the
battery slightly at the same time. The purpose of Float stage is to offset the power
consumption caused by self consumption and small loads in the whole system, while
maintaining full battery storage capacity.
In Float charging stage, loads are able to obtain almost all power from solar panel. If
loads exceed the power, the controller will no longer be able to maintain battery
voltage in Float charging stage. If the battery voltage remains below the Recharge
Voltage, the system will leave Float charging stage and return to Bulk charging stage.
