Equalize Menu

• EQUALIZE – This menu allows you to enable equalize charging.
Equalize charging (or equalizing) is a controlled overcharge of the batteries.
It helps to mix the battery electrolyte and attempts to reverse the build-up of
stratifi cation by removing sulfates that may have built up on the plates. These
conditions if left unchecked, reduce the overall capacity of the battery bank.
Default setting: EQUALI ZE = Disabled
Settings: Disabled, Request , EQing
How do I enable equalize charging? Equalization charging can only be
enabled while the charger is in Float Charge or Full Charge. To enable, press
the MENU button until you see the "Disabled" menu, then press the CHANGE
button. The display quickly reads "Request ", then "EQing."
The Equalize Charge lasts for four hours, and then automatically stops and
returns to Float Charging. The Equalize Charge can be manually stopped by
pressing the MENU button until you see the "EQing" menu, and then pressing
the CHANGE button until the display reads "Disabled".
How often should I equalize? Some experts recommend that heavily
used batteries should be equalized periodically, ranging anywhere from once
a month to once or twice per year. Other experts only recommend equalizing
when the cells have a low specifi c gravity reading, or when the difference
between any individual cell has a reading >.015 after being fully charged.
How long should I equalize? While the batteries are gassing, monitor the
specifi c gravity readings every hour. When the specifi c gravity readings no
longer increase, the Equalization charge is complete and should be stopped.
WARNING: Do not perform an Equalization charge without
reading and following all safety precautions pertaining to charging/
equalization as noted in this manual and provided by the battery
manufacturer, and any equalization information in the inverter
owner's manual.
CAUTION: Ensure your batteries can be equalized—only equalize
your batteries if permitted by your battery manufacturer. Performing
an Equalize Charge on batteries other than liquid lead acid or certain
AGM types could permanently damage them. Refer to your battery
manufacturer on how to properly equalize your batteries.
Info: Equalization charging is not available if either GEL, AGM 2,
or LFP is selected from the Bat t ery Type menu.
