Hi LittleBill,

I believe the Champion 3400 does shut down loads before spinning down when using the remote.

I know my Yamaha 3000 Sieb has manual switches for the output sockets.

inverter gens are different then regular, once they can't hold the output, they disconnect, not like a normal generator where the avr trys the entire time the generator is winding down.

NO..it doesn't ... think about it

the ATS in the RV does not connect the RV to generator until after the the generator has started running, there is NO load on the RV generator until the ATS closes, then the A/C can come on

While there is nothing that can be done about a generator running out of fuel, my EMS-HW30C ensures that there is no load when I start the generator. Since my generator has a floating neutral, I unplug the bonding plug before shutting the generator down. Doing that ensures that the EMS-HW30C has removed the load from the generator.

Is it the end of the world...one time and the generator is toast...no

Is it good practice...no.

To the generator a tripped breaker looks like a normal shutdown of load.

There are several factors.. Traditional generators when they are shut down do some funky stuff that in THEORY can damage the loads (I am ordering a new start cap for one A/C today. that may be why) but in truth the danger is slight. Also there is a SLIGHT danger to the genny.

INverter generators when they shut down generall do it HARD (Like a breaker tripping) they just flat shut off.. But here the key phrase is I THINK THAT IS HOW THEY WORK. no guarantee.

But LAWYERS review owner's manuals and the precautions therein before printing.

Probably written for the one time a generator broke because of sudden shutdown and someone complained and got it replaced.

Now the lawyers ensure that text is there to protect themselves.

Learn to be easy on machinery. Shut down the load. Let the machine idle and cool off. This works for truck engines, generators, etc. It is very important with solar controllers to shut them down in the right order for instance. Never disconnect from the battery side with power coming from your solar panels.

But the AGS does shut down the generator with the A/C load connected, which is the topic.

On our onboard genny there were a couple of instances where my DW had turned off the genny while under heavy load, as well as started the Onan with a heavy load. Thankfully all was well after those episodes, I subsequently explained the reasoning why those actions can cause damage, although for the most part we always have some nominal load when turning the genny off or on.

After a decade of dutiful service from our Onan, which was overkill most of the time anyways, we decided to purchase a portable inverter genny that could run our RV AC unit while being fuel efficient and less noisy. We picked up a Champion inverter genny with remote start. When using the remote loads do not need to be removed, loads do need to be removed for electric or pull cord start up.

And when the generator stops?
