Stop Absorb
Full name Stop at Absorption Charge Stage
Purpose The “Stop Absorb” triggers enables the Xantrex XW AGS to stop the
generator when the inverter/charger has recharged the batteries to the
Absorption stage.
Considerations Set “Stop Absorb” if it’s desired to only deliver a partial charge to the
batteries. The Xantrex XW AGS will start and run the generator until the
inverter/charger charges the batteries through the Bulk charge stage
(restoring the batteries between roughly 75% and 90% of their full
charge). The Xantrex XW AGS stops the generator when the inverter/
charger determines the batteries have reached the Absorption charge
stage.
Because Stop Absorption will shut down the generator before the
batteries are fully charged, it is recommended to use it only if there is an
alternate charging source, such as wind or PV, which can complete the
charge. If the generator is the only charging source, Stop Absorption will
leave the batteries consistently undercharged and may shorten the
battery life. Alternately, Stop Absorption can be useful during utility
outages, when it is desired to keep the generator run time to a minimum,
but are expecting a full recharge once the power is restored.

Charger Operator’s Guide.
