Configuration of the Xanbus AGS
Stop Float
Full name Stop at Float Charge Stage
Purpose The "Stop Float" trigger allows the AGS to stop the generator when the inverter/charger has recharged the batteries to the Float stage.
Stop Absorb
Full name Stop at Absorption Charge Stage
Purpose The "Stop Absorb" triggers enables the AGS to stop the generator when the inverter/charger has recharged the batteries to the Absorption stage.

Considerations "Stop Float" or "Stop Absorb" would typically be used if the generator was started due to a
"Stop Float" is the recommended setting if it is desired that the generator charge the batteries completely. This will result in somewhat longer run times. However, if the generator is the primary charging source, charging them to the Float stage every time will provide longer battery life.

Considerations Set "Stop Absorb" if it’s desired to only deliver a partial charge to the batteries. The 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 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.
