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 “CV/CC Controlled” displays on this menu’s screen, you will not be
able to adjust the settings because “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
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
<4.0, even though you can adjust the setting from 0.1-25.5 hours,
this range may not be recognized by the inverter, and could cause
the charger to revert to the default setting of 2.0 hours. See Table
3-1 for the remote setting and inverter compatibility level required.
