• Set Start Gen AC Amps – This setting determines when the generator
would start depending on the AC amps level of the load the inverter is
running. In order for the generator to autostart, the load's amps level
must be maintained continuously above the Start Gen AC Amps setting
for the duration of the Start Amps Delay setting.
Default setting: Set Start Gen AC Amps = OFF
Range: OFF, 5-60 Amps
• 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 = 120 Seconds
Range: 0-127 Seconds, 1-127 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. In order for the generator to autostop, the load
amps level must drop continuously below the Stop Gen AC Amps setting
for the duration of the Stop Amps Delay time setting.
Default setting: Set Stop Gen AC Amps = 4 Amps
Range: 4-59 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 = 120 Seconds
Range: 0-127 Seconds, 1-127 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 Stop Gen AC Amps just below
the start amps to ensure 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 drop quickly. 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 will turn 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 (see ME-BMK owner's manual) as
shown on the METER button's 04A BMK SOC display. This is considered the
best overall method for using AGS settings to start and stop your generator.
Note¹ – For a 4000 watt inverter, set Start Gen AC Amps at 25A.
