According to OutBack, the AGS’s 2 Minute Voltage Start is “considered an emergency start set point and
… will start the generator regardless of
Quiet Time settings.” Programming this parameter according to the
settings listed in Table 8.0 above ensures that the battery does not discharge below ~80% Depth of
Discharge. Triggering the generator to turn on from the
AGS Voltage Start setting not only results in the
loads being powered from the generator instead of the PHI battery bank, but also initiates a full battery
charge cycle via the inverter/charger.
According to OutBack, AGS “ Load Start will start a generator whenever the total system AC load wattage
exceeds the
Start set point for the programmed amount of time ( Delay ). The generator will then be
stopped when the AC load has dropped below a Stop set point for a programmed amount of tie (
Delay ).”
This setting is especially useful when a PHI Battery bank is slightly under-sized relative to the inverter’s
Load Rate (refer to
Section 3.1 – Sizing for Maximum Instantaneous Discharge). If the PHI Battery bank is
sized such that the its maximum continuous discharge rate meets or exceeds the inverter’s Load Rate, it
is unnecessary to utilize this setting.
When the generator is running because of Load Start, the inverter system will charge the batteries.
However, it is not programmed to perform a complete charge cycle. If the generator stops upon reaching
its
Stop criteria/set point, the charge might not be completed.
AGS Voltage Start and AGS Load Start settings can be used in parallel. Whichever condition is met first
starts the generator.
Because PHI Battery SoC readings in the OutBack equipment are unreliable in partial charging
applications, SimpliPhi recommends against using the AGS SoC Start parameter and favors the AGS
Voltage Start and/or AGS Load Start parameters instead.
