· Float Charge
After the battery is fully charged in Boost voltage stage, the controller
reduces the battery voltage to Float voltage set point. 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
charge.
· Equalize Charge
WARNING: Risk of explosion!
Equalizing flooded battery can produce explosive
gases, so well ventilation of battery box is
necessary.
