Equalization: Is carried out every 28 days of the month. It is intentional overcharging of
the battery for a controlled period of time. 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.
Once equalization is active in the battery charging, it will not exit this
stage unless there is adequate charging current from the solar panel.
There should be NO load on the batteries when in equalization
charging stage.
Over-charging and excessive gas precipitation may damage the
battery plates and activate material shedding on them. Too high of
equalizing charge or for too long may cause damage. Please carefully
review the specific requirements of the battery used in the system.

Other Considerations
Use a multi-meter to check the voltage of the battery.
Make sure the battery voltage is not exceeding the rated
specification of the charge controller. Disconnect battery.
Confirm that there is a tight and correct connection from
the battery bank to the charge controller and the solar
panels to the charge controller. Use a multi-meter to
check if the polarity of the solar modules have been
reversed on the charge controller’s solar terminals.
Check the rated battery voltage. The LCD will not display
on the charge controller unless there is at least 9V
coming from the battery bank.
Everything is connected
correctly, but the LCD on
the controller does not
turn on
Charge controller does not
charge during daytime
when the sun is shining on
the solar panels.
Use a multi-meter to verify the rated battery voltage.
Disconnect any loads connected to the battery to allow it
to charge.
