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 XW Auto Generator Start 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 XW Auto Generator Start will ignore it until quiet time ends.
If the condition still exists at the end of quiet time, the XW Auto
Generator Start 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 XW Auto Generator Start is in
Automatic mode. This setting requires “QT En” be set to [Enabled] and
also requires a setting for the “QT Begin” trigger. This setting is triggered
by the setting on the system clock, so ensure the clock on the 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.
Value Description
12:00AM to 11:59PM
(12-hour clock)
00:00 to 23:59
(24-hour clock) 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”.
