Does anyone know what size genset would be best for an electric coach. I have found a few good deals on 8-9 kw, but don't know if they are big enough. It is for an Eagle. I will use propane for the stove, but electric for everything else. |

9kw @ 120v gives u 75 amps of available pwr. Add up your total load to see if it exceeds that. Even if it does, ask yourself, are u going to use it all at the same time? I would base my genset on what I came up with for a "normal" average load, rather than the max. I know several all electric coaches operating just fine on 8 kw w/ a minimal amount of sensible use. This is assuming u want to save a little money, conserve a little on electric use, and save some bay area. Aside from the cost, some of these 12-15 kw units get huge in physical size. Just an observation on my part |

Eric. I too am doing an all electric Eagle and I am using a 7 KW Power Teck. My electrician has assurded me that it more than cover my needs.

Eric,
Think before you purchase any large items... You can always buy a generator big enough to run anything that you can cram into a 40' shell...
BUT, unless you want to run that genset 24/7, you better limit yourself to the 50A MAX that is available at campsites. (30A at many)
Just a point to ponder.......

YES YES!
This is the key to having a TEC [Total Elecrtic Coach} that CAN be used in campgrounds.
AS most campgrounds will ask you to leave if you run a genset on a site.
The many 240V 50A plugs now seen in campgerounds are only wired for 120V 30A .
The reasons are twofold , they dont want to rewire the entire park, they also dont want to charge $20 a night for a clown using $40 worth of juice.
When you find a brand spanking new METER at your campsite , you may have 240/50 , and you may also be billed for what you use.
If you have to go TEC for some reason , build one you can USE!

I have a 12.5 KW Kohler generator with a Perkins 4108 engine. If I want to load the generator so it doesn't carbon up I need to run AC and heating at the same time. It is not a TEC. If I have to replace my generator at some time I will probably put in an 8 KW with a 3600 watt inverter to help when we turn on the microwave and stuff all at once.
I've seen it written that newer generators are less sensitive to running at low loads than my perkins engine.
Also I will make any future generator 120 volt exclusively so it is not necessary to balance loads. If you are buyin a new one they can set up the generator for 120 volt for you by changing a few connections. If you ever need 240 volt for future equipment, you can have it changed back.

Eric, if you are going to have propane on-board for the stove anyway, why not use it for heating and refrigeration too? Just remember a genset wants to run at at least half capacity when you do your calcs. |

This is a great idea for having the gen set fully loaded,
BUT be sure to tell the inverter Mfg that this is how you will use his product.
Its a different brain board when you want to boost a sagging genset volts and cycles,
rather than matching grid current.

What does one have to do with the other? Why would u rely on an inverter to correct the output of an independant a/c source, which, if it is operating correctly, will produce 60 cycle 120. All quality inverters that I am familiar with switch from the inverter mode when they sense an outside source and will literally blow up if they don't! If the genset is running, the inverter is out of the line and will have no impact whatsoever on those little power lapses that occur in gensets with the sudden demand of a heavier load. If you use the inverter strictly on dedicated loads, then u defeat the purpose of dual sourcing power. |

I have a 15KW run by a 2/53 detroit I have a totally electric rig including a regular size electric stove and oven (220) and side by side fridge. I have two roof airs with heat and also run a hydraulic pump off the 2-53 to turn the A/C compressor for the original bus A/C. I use a hospital zone muffler and it runs pretty quiet. I have a 100 gal fuel tank for the gen set and always have it running when I am on the road in hot weather. |

jmaxwell- Go to the Trace site and read. The sine wave inverters supplement the ac source, either genset or line, when the load exceeds the supply. When the load eases, it reverts back to charging. Never skips a beat doing it. I love mine.
