Table 3-2, Battery Amp/Hrs Capacity to Suggested Absorb Time
• 03D Absorb Done: This setting identifi es whether time, amps, or SOC are used to determine
when the Absorption charge stage is fi nished and transitions to the fi nal charge stage (see 03F
Final Charge Stage) afterwards. Absorption is the second stage of the battery charge process
that attempts to fully charge the batteries.
Note: If “CC/CV Controlled” displays on this menu’s screen, you will not be able to adjust the
settings as “CC/CV” has been selected as the battery type from the 03C Battery Type menu.
Default: Absorb Done Time
CAUTION: If the Absorption stage is short or terminated, the batteries may not receive
a full charge. In contrast, if the Absorption stage is too long the batteries may be
overcharged. Either scenario may lead to damage to the batteries. Contact your battery
manufacturer to ensure the best charge settings are used for your type of batteries.
◊ Set Absorb Done Time – Set Absorb Done Time is used when a specifi c time is determined
to be the best solution for ending the Absorption stage. When using time, the battery bank
size will typically determine the length of the Absorb Done Time setting. The larger the battery
bank, the longer the absorb time needed to ensure a full charge to the batteries. Taking specifi c
gravity readings of the batteries and adjusting the absorb time may be needed in order to
obtain the appropriate absorb time for your battery type and battery bank size. Use Table 3-2
to select the Absorb Done Time setting based on the amp-hr capacity of your battery bank.
Default setting: Absorb Done Time = 2.0 Hrs
Range: 0.1-25.5 Hrs
Info: Range of the Absorb Done Time setting is dependent on the inverter’s compatibility
level. With a compatibility level of ≥4.0, the available range is 0.1-25.5 hrs. However,
if the compatibility level is less than 4.0, even though you can adjust the setting from
0.1-25.5 hours, the available range may not be recognized by the inverter, and causes
the charger to revert to the default setting of 2.0 hours. See Appendix B for more info.
□ EQ Volts – Sets the level at which the charging voltage is held constant during an
Equalization cycle. Note: Cannot be set lower than the Absorb Volts setting, or more than
2 volts (12v systems), 4 volts (24v systems), or 8 volts (48v systems) above the Absorb
Volts setting.
Default: 15.6 Volts (12v), 31.2 Volts (24v), 62.4 Volts (48v)
Range: 12.0-16.0 Volts (12v), 24.0-32.0 Volts, 48.0-64.0 Volts (48v)
□ EQ Time – Sets the time (duration) the battery will charge at the EQ Volts setting.
Default: 4.0 Hrs
Range: 0.1-25.5 Hrs
Info: The timer for the EQ Time setting (SETUP: 03C Battery Type/Custom menu):
a) Counts when EQ is enabled and the voltage is close to the EQ Volts setting (≥0.1v/12-
volt systems, ≥0.2v/24-volt systems, or ≥0.4v/48-volt systems).
b) Pauses when in Charger Standby.
c) Clears when EQ is fi nished, battery goes to Bulk/Absorb or Float, or EQ is stopped.
