FWIW

My rig has a Southwire 40100 ATS. This ATS allows 30 seconds from generator start to power transfer.

Here are a few notes from their guide.

Note that the ATS takes approximately 30 seconds to complete the transfer from shore power to generator power after the generator is started.


Note that when heavy electrical loads like air conditioners and heaters are on when transferring from shore to generator power, a current “inrush” will occur. This current inrush causes an instantaneous demand for current on the generator that, depending on the capacity of the generator, can result in a voltage drop below the Transfer Switch’s low voltage threshold of 90V. The effect of this will cause the transfer switch to not transfer and/or contactor chattering.

Turn off heavy loads like the air conditioners and heaters before turning on the generator. After the generator is running and the RV successfully transferred to generator power, turn on the loads one at a time.

For the AGS to turn on start the generator and then AC the AC must be turned on and thermostat set. This goes against the two statements from the ATS guide.

I will operate my generator and AC the safe way while traveling rather than doing things the lazy way. If we are in the coach the my generator gets started after disconnecting shore power and I start it myself, no AGS required.

Again, FWIW
