3.0 Setup
• SETUP: 03 Absorb Time – Used to determine when the charger
completes the Absorption stage and transitions to the Float stage.
Absorption is the second stage of the battery charging process and the
batteries will be almost fully charged. Refer to Table 3-2 to correlate the
battery capacity to the absorption time.
Default setting: Absorb Hrs = 1.5
Range: 0.1-25.5 Hrs
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 04 Battery Type menu.
Info: 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
cause damage to the batteries. Contact the battery manufacturer
for the best charge settings for your type of batteries.
Info: The range of the Absorb Time setting is dependent on the
revision of your inverter. With inverters having a revision 5.0 or
greater, the available range to use is 0.5-25.5 hrs. However, if your
inverter revision is less than 5.0, the actual range is only from 1.0
to 6.5 hrs. Any setting less than 1.0 hr or greater than 6.5 hrs is
not recognized and will cause the charger to revert to the default
setting of 1.5 hrs.
Info: The higher the LBCO setting, the less the inverter discharges
the batteries; which allows the batteries to have a longer life. The
down side to a higher LBCO setting is the need to charge more often
to prevent the inverter from shutting off in Fault mode.
Info: If there is an AGS-N installed, it should be set to start ≥1.0
volts higher than the LBCO setting—this is to prevent the inverter
from shutting down before the generator comes on.
