Sometimes automatic start or automatic stop triggers may overlap with
the beginning and end of quiet time. Three different quiet time scenarios
affect when the generator stops and starts.
1. If quiet time begins after the Xantrex XW AGS has started the
generator, the generator will stop. If the condition that started the
generator is still present when quiet time ends, the generator will
restart.
2. If a condition that requires starting the generator occurs during quiet
time, the Xantrex XW AGS will ignore it until quiet time ends. If the
condition still exists at the end of quiet time, the Xantrex XW AGS will
start the generator.
3. If the running generator stops when quiet time begins and a
condition that requires stopping the generator occurs during quiet
time, the generator will not restart when quiet time ends.
QT Begin
Full name Quiet Time Begin
Purpose “QT Begin” defines the start of quiet time.
Dependencies “QT Begin” functions only if the Xantrex XW AGS is in Automatic mode.
This setting requires “QT En” be set to [Enabled].
Ensure the clock on the Xantrex XW System Control Panel is set to the
correct local time.
Important: If quiet time is set for overnight, be aware that overnight
battery drain can be significant as it may be necessary to use the
inverter and batteries to supply AC Power without the help of a generator.
Therefore, it is important to conserve battery power during this time.
Minimize the use of interior lights and set thermostat temperature lower
to prevent the furnace from coming on at night during cool weather. Set
thermostats higher to prevent air conditioning coming on at night during
warm weather.

At the time set for “QT Begin”, the generator will
stop (if it is running) and not be able to start
again until the time set for “QT End”. It ignores
all automatic start triggers during the time
period between “QT Begin” and “QT End”.
