Every time when the controller is powered on if it detects neither over discharged nor overvoltage the charging will enter into boost charging stage Float Charge After the Boost voltage stage the controller will reduce the battery voltage to Float voltage setpoint When the battery is fully recharged there will be no more chemical reactions and all the charge current transmits 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 battery and prevent the gassing also 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 stage loads can continue to draw power from the battery In the event that the system load s exceed the solar charge current the controller will no longer be able to maintain the battery at the Float setpoint Should the battery voltage remains below the boost reconnect charging voltage the controller will exit Float stage and return to Bulk charging Equalize Charge Certain types of batteries benefit from periodic equalizing charge which can stir the electrolyte balance battery voltage and complete chemical reaction Equalizing charge increases the battery voltage higher than the standard complement voltage which gasifies the ba
