Diesel RVs: Re: [diesel_mercedes] Dave here in s..e Ind. mb gen set.

Ya got me. I have no idea how small a 4 cyl MB engine can be. The only one I have is 2.3 liters, could likely power a genset big enough for a small apartment building.

100 amp service means everything on the line can draw up to 100 amps, has near enough to nothing to do with KW/hrs. you are using. My little diesel genset is a 5kw unit, rated to put out 52 amps at full speed.

There is a handy gizmo available from Amazon called a Kill-A-Watt meter, you can plug it in to a wall fixture, plug about anything you are using into the meter, it will provide real time read out of watts, amps, KW/hrs, that the device is using, depending on your menu choice. Cost about 20 bucks..

Got to confess total ignorance of RV power usage.

    So what? The listing doesn't mention engine size, it just says 4 cylinder MBZ. That could be anything from about 1.0 to 2.6 ltrs.

    12.5 kw is not huge. Most houses run 100 amp service, which is about 12 kw, isn't it?

    I know that for location shoots, we'll line up multiple truck mounted gen sets running 100 or 150 kW EACH. Most of that is for lighting. But when you add in craft services and honey wagons and dressing rooms, you get a lot of amps lined up pretty fast.

    There are plenty of big RVs that have over 10kw gen sets and use the power for big AC units for desert fun.

    Probably be great for a household, or vacation home standby generator, or even for a big RV.

Naw, it's too big, is my point, regardless of what it's attached to. You do this kind of calculation backward, figure out how many KW/hrs you require, then how big a gen head to get those numbers, then how big (small) and engine to fit to do the job. For the above mentioned tasks, 2-5 kw, perhaps 250-500 cc engine... Got one 5k gen powerd by a 5 hp B&S (don't know the displacement), and another powered by a 440cc diesel single...The little Deutz engine runs a 120v single phase gen head, the B&S does single phase 120 or 240..

I agree exactly with you design idea. No idea how to compare reefer output to KW, KW/hrs, which would imply the thing is driving generator, not a reefer..

No worries, I get days like that too...

Could you please expand upon your claims/ideas. I mean these things spend months on container ships at constant revs and are designed for the volume entailed. 2-5 kw would depend on the size of the area to be accomodated and of course the ambient temperatures to contend with for the duration and the degree of insulation of the area being heated or cooled. When referring to KW is that max effect or constant and is that peak or KWH - sheesh! Sorry it's been a really bad day...
