My head hurts!

Pat,

I have a 3kw Yamaha and it has no problem kicking the A/C on. The only thing that it can't do your me is run the A/C and another high draw at the same time, being as I only have a 20A receptacle on the generator.

I agree leave everything alone, until you get your set up together.

Another little ditty, "If it ain't broke, don't break it."

I get so mad whem I do that!

Jim

What can I say... Been there done that and got the T shirt!!
Broke it when it didn't need to be fixed!!!
Guess I've been getting carried away with anticipation.. Cant wait
for our first adventure and want to be prepared.. Spring seems a long way off.
Having said that.. The good advice here certainly has helped me avoid a
major faux pas..
Pat

I was hoping to avoid turning everything off just to run the AC. It can get pretty hot and humid in our neck of the woods in July and August.


I just checked out your link and I'll definitely give the "hard start cap" a try. It would be the simplest solution.. Especially since you're able to start yours with a 2400 watt gen set.




I do plan on picking up a couple of Powerhorse inverter generators at Northern Tool for my no-hookup camping. Running them in parallel Delivers 3.6 K watts continuous and 4K surge watts. If the Capacitor doesn't work I would plan to run a separate line to the AC and install a switch to be able to run the ac from either the shoreline or Generator set.




It may be a while before my first shakedown trip but I will post my experiences when I do..
Thanks again
Pat
One thing we commonly forget is that the 12V converter demands a lot of power to charge empty batteries. It's always good to start generator and wait for 10-15 mins to ensure the batteries are demanding a bit less from the converter. Or you can also switch off the converter breaker to start the AC and turn it back on after it runs.

I also have the Yamaha 3000 SEB inverter unit, bought in 2008. Generator had no issues with the 13.5 Dometic A/C on my old travel trailer but as stated above had to turn off high draw appliances when starting the A/C. I like that it dips into the electric start battery if needed for extra power, and very quiet. It is now a home backup for the last 4 years, but has never given 1 bit of trouble.
