Using an AGS Module: Setup
• Set Quiet Time Topoff – Sets the time period the generator will autostart and run before
Quiet Time starts. The generator will only start on Quiet Time Topoff if the battery voltage is
within 0.3 volts¹ or less of reaching the 04A Gen Run VDC start parameter, or the battery’s
SOC is within 4% or less of reaching the 04D Gen Run SOC start parameter².
Default setting: OFF
Range: OFF, 30-120 Minutes (30 min intervals)
Why should I use Quiet Time? Quiet Time is used when there are park rules or local regula-
tions that prohibit generators from running (i.e., noise requirements during sleep hours). If there
are no local rules or regulations, you may not want to use Quiet Time—which would allow the
generator to run at any time in a 24-hour period.
Where should I set Quiet Time? Set the Quiet Time start and stop settings to coincide with
local noise requirements, or for a specifi c time period that you do not want the generator to au-
tomatically run each day.
What is Quiet Time Topoff? The Quiet Time Topoff feature charges the battery prior to the
start of Quiet Time in an attempt to prevent the inverter from shutting down from a low battery
condition during the entire Quiet Time period. The Quiet Time Topoff feature is enabled whenever
you select a time from the Set Quiet Time Topoff menu.
The Set Quiet Time Topoff setting determines how long the battery voltage is monitored before
the start of Quiet Time. During the topoff time period, if the battery voltage is 0.3 volts¹ or less of
reaching the 04A Gen Run VDC start parameter, the generator will automatically start and charge
the batteries before Quiet Time turns the generator off.
If an optional Battery Monitor Kit (ME-BMK or ME-BMK-NS) is installed and enabled, the Quiet
Time Topoff feature will also autostart the generator if the battery’s SOC is within 4% or less of
reaching the 04D Gen Run SOC start parameter during the topoff time period.
Where should I set Quiet Time Topoff? Normally, setting Quiet Time Topoff to 30 or 60
minutes is a good idea. In cases where the DC or inverter loads are unusually high or the SOC
autostart setting is low—which may cause the batteries to be heavily discharged during the Quiet
Time period—increase Quiet Time Topoff to 90 or 120 minutes; this ensures the batteries receive
the maximum charge time before Quiet Time shuts the generator off.
Info: When the generator starts on Quiet Time Topoff, it continues running until it
reaches the Quiet Time start parameter—even if the VDC or SOC autostop parameter
is reached.
Scenario example (Topoff based on battery voltage): The 04A Gen Run VDC menu is set
to start at 11.5 VDC, Quiet Time is set to start at 10PM, and the Quiet Time Topoff setting is 60
min. At 9PM, the battery voltage reaches 11.8 VDC; because the Quiet Time Topoff feature is
enabled (60 min.) and the battery voltage is within 0.3 volts of the 04A Gen Run VDC setting,
the generator autostarts to allow the batteries to charge for 60 minutes before Quiet Time turns
the generator off.
Scenario example (Topoff based on battery SOC²): The 04D Gen Run SOC menu is set to
start at 60%, Quiet Time is set to start at 10PM, and the Quiet Time Topoff setting is 120 min.
At 8PM, the battery SOC reaches 64%; because the Quiet Time Topoff feature is enabled (120
min.) and the battery’s SOC is within 4% of reaching the 04D Gen Run SOC start setting, the
generator autostarts to allow the batteries to charge for 120 minutes before Quiet Time turns the
generator off.
Note¹: This voltage is scaled depending on your battery system; ≤0.3 for 12-volt systems, ≤0.6
for 24-volt systems, and ≤1.2 for 48-volt systems.
Note²: Requires the optional Battery Monitor Kit (ME-BMK or ME-BMK-NS) to be installed and
enabled.
