Default setting: Set Stop Gen AC Amps = 10 Amps
Range: 0-60 Amps
• Set Stop Amps Delay – This setting determines the amount of time
that the AC load must be continuously smaller than the Stop Gen AC
Amps setting before the generator automatically stops.
Default setting: Set Stop Amps Delay = 60 Seconds
Range: OFF, 1 - 120 Seconds, 3 - 127 Minutes
Where should I set Gen Run Amps? Typically, the generator should start
when the AC load amps is >70-75% of the inverter AC current output rat-
ing¹. This keeps the inverter from running too large a load and also keeps
the batteries from cycling unnecessarily. Set the Stop Gen AC Amps just be-
low the start amps to make sure the large load has turned off. Set the start
delay time so surge loads don’t trigger a false start, and the stop delay time
is long enough to ensure the load has turned off.
Amps Start/Stop Example: In this scenario, most AC loads typically do
not exceed 20A when in Inverter mode. When a freezer or well pump starts,
the load exceeds 30A so the battery voltage starts to quickly drop. Instead
of cycling the batteries to a low voltage, set Start Gen AC Amps to 25A with
a 60-second delay (using Set Start Amps Delay menu). Set the Stop Gen
AC Amps menu to 20A with a 60-second delay (using Set Stop Amps Delay
menu). After 60 seconds of detecting a larger than 25A load on the inverter,
the generator autostarts and powers the loads and recharges the batteries.
Once the AC amps load drops below 20A for 60 seconds, the gen turns off.
SETUP: 04D Gen Run SOC Menu
Info: This feature requires the optional ME-BMK (Battery Monitor
Kit). Refer to your ME-BMK owner’s manual to operate.
This menu starts and stops the generator based on the SOC (State of Charge)
reading from the attached battery monitor, as shown on the METER button’s
04A BMK SOC display. This is the best method for using AGS settings to
start/stop your generator. Since the ME-BMK already uses voltage, time, and
current to determine the true SOC of the batteries, there is little guesswork
or calculating needed to determine what settings to use.
• Set Start Gen SOC – This menu is used to set the SOC level for auto-
starting the generator.
Default setting: Set Start Gen SOC = OFF
Range: OFF, 20% - 90%
Note¹ – For a 4000 watt inverter, this would mean setting Start Gen AC
Amps at 25A.
• Set Start Amps Delay – This setting determines the amount of time
that the inverter load’s current must continuously remain above the
Start Gen AC Amps setting for the AGS to initiate an autostart.
Default setting: Set Start Amps Delay = 60 Seconds
Range: OFF, 1 - 120 Seconds, 3 - 127 Minutes
• Set Stop Gen AC Amps – This setting determines when the generator
would stop depending on the drop in the AC amps needed for the load
the inverter is running. The load amps level must continuously drop
below the Stop Gen AC Amps setting for the duration of the Stop Amps
Delay setting in order for the generator to autostop.
