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
WARNING: Risk of explosion!
Equalizing flooded battery can produce explosive gases, so well
ventilation of battery box is necessary.
NOTE: Equipment damage!
Equalization may increase battery voltage to the level damaging to
sensitive DC loads. Ensure that all load allowable input voltages are
greater than the equalizing charging set point voltage.
NOTE: Equipment damage!
Over-charging and excessive gas precipitation may damage the battery
plates and activate material shedding on them. Too high an equalizing
charge or for too long may cause damage. Please carefully review the
specific requirements of the battery used in the system.
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 battery electrolyte.
