Using an AGS Module: Setup
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.
Why would I use Quiet Time? Quiet Time is used when there are park rules or local regulations
that prevent generators from running (e.g., 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 begin and end settings to coincide with
local noise requirements, or for a specific time period that you do not want the generator to
automatically 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 under the Set Time to Topoff Battery before Quiet Time menu.
The Set Time to Topoff Battery before Quiet Time (or “topoff time period”) 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 DC Volts 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—you may want to 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 QT 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 DC Volts 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 DC Volts start
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 SOC¹): 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 at least 120 minutes before Quiet Time turns the
generator off.
