Equalize Stage
WARNING: Risk of Explosion
Equalizing vented batteries produces explosive gases. The battery bank must be properly
ventilated.
!
CAUTION: Equipment Damage
Equalization increases the battery voltage to levels that may damage sensitive DC loads. Verify
all system loads are rated for the temperature compensated Equalize voltage before beginning
an Equalization charge.
!
CAUTION: Equipment Damage
Excessive overcharging and gassing too vigorously can damage the battery plates and cause
shedding of active material from the plates. An equalization that is too high or for too long can
be damaging. Review the requirements for the particular battery being used in your 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.
If it detects that the battery is being over discharged, the solar controller will automatically
turn the battery to equalization charging stage, and the equalization charging will be
120mins. Equalizing charge and boost charge are not carried out constantly in a full
charge process to avoid too much gas precipitation or overheating of battery.
