I had run the 13.5k in my previous 5th with my Yamaha 2400 with no issues, no additional capacitor needed.

I rolled the dice and got a 15k unit with our new fifth wheel. No go running it with the 2400. I added a Supco SPP6 and it runs now. I only do this occasionally, when we are without hookups and need the break from the heat. It works fine for us.

Ran my duo therm 7200 btu ac on the new yamaha 2000 inverter genny. Worked fine, even ran it on eco with fridge on after the ac was on for a while. Batt were fully charged, so charger did not draw anything.


Lets ride! were not getting any younger!

Installed the supco today. real easy to do, cleaned the coils too, and discovered why I had a leak sometimes while the ac was running. Mud daubers made a mess, and had the water backing up.

How much difference will using non alcohol gas make in starting your a/c? I bet not using it why many 2000's gennys will not start the smaller a/c'c.


Been using non-ethanol gas from day 1

Kudos! This really is the best way to go IMHO. It will start a compressor with lower line voltage than simple upgrading of a capacitor. Also these things VASTLY increase the life of a capacitor. Bookmarked the link!


mxwanderer: Just wondering if you mean increase the life of the genny?

We like the yamaha 2400iSHC for its portability and low noise level, 4 yr warranty, and price (1200). However, it would be nice to be able to turn the eco mode on and off, as well as a bypass to the inverter with a 220v outlet.
Although we have already bought and installed the DuoTherm hsk, we might at one point consider the smart start if the impact on the genny cannot be mitigated. When the compressor kicks on the first time or if we jack up the cold thermostat during operation, the genny goes very low and almost sounds like it's going to stall, but never does! And doesn't overload as well.
However, inside the tt, the full brown out conditions are very evident...the a/c struggles and goes very low for about 2 or 3 seconds, the m/wave shuts off and start up again, etc...
Doesn't make me feel to good especially if the fridge is on auto at that time and choosing to run off a/c.
Don't like the impact to the electronics at all, so if the new auto electric place tells me the hsk is in fact connected correctly, I will probably go with one of these, as mentioned above.
thanks again to all for the very helpful directions to look at, suggestions, and advice
gratefully appreciated
cheers

Sure wish my fridge had a gas only switch just for that reason. guess I will have to turn it off while starting a/c on genny, then back on after start. Lots to remember when using a marginal one.

This is not possible with the design of the system.

Me Book Mark Two...

AND LINKED HERE FOR SELLER

AND HERE FOR MANUFACTURER

I found some made by Schneider/SquareD but the 115V didn't seem to have the amps capacity needed for an A/C.
