In power systems with long cables between the batteries and the inverter/
charger (over 10 feet [3 m]), the measured battery voltage can be a poor
indicator of battery condition. In such cases, the batteries are more
assured of a full charge if the generator runs until the charger reaches the
Absorb stage, rather than waiting until the charger charges the batteries to
the voltage you may have set for “StopBattV” (see page 3–22).
For more information on battery charging, see your inverter/charger
operation guide.
Outcomes If you enable the Auto Gen Start to stop the generator at the Absorption
stage, it will stop the generator if it has been started automatically by the
Battery Voltage (“StartV:30sec”, “StartV:15min”, “StartV:2hr”, and
“StartV:24hr”) or State of Charge settings.
If you do not set “Stop Absorb” to On, the Auto Gen Start will not stop
the generator in response to the battery charging stage. The generator will
stop in response to battery voltage (“StopBattV”) instead. In this case,
ensure that the “StopBattV” is enabled and set at the correct voltage.
Stop Float
Full name Stop at Float Charge Stage
Purpose The “Stop Float” setting allows you to set the Auto Gen Start to stop the
generator when the inverter/charger has recharged the batteries to the
Float stage.
When to use Set “Stop Float” if your inverter/charger is using three-stage battery
charging.
Set “Stop Float” to On if battery charging is your main priority for your
generator (rather than using your generator for powering high AC loads).
You might also use the “Stop Float” setting if your batteries are not being
charged enough before the Auto Gen Start stops the generator because of
battery voltage or state of charge.
In power systems with long cables between the batteries and the inverter/
charger (over 10 feet [3 m]), the measured battery voltage can be a poor
indicator of battery condition. In such cases, the batteries are more
