Equalize Charge
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.
Every month 28
th
solar controller will engender equalize charging stage. It will remain
120mins when equalize stage is constant, or it will remain 180mins when equalize
charging accomplishes off and on. 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.
