I have a question about the Ventrac Model HG150 electrical generator when driven by the Model 4500Y tractor.
The short version: How many kW of electrical power are available at the HG150's output when driven by the 4500Y?
The much longer version:
======================================
In anticipation of the arrival of my Ventrac 4500Y tractor and HG150 Generator, I am trying to determine which electrical loads within my home I will be able to power via a suitable transfer switch and possibly a third circuit-breaker panel fed via the transfer switch. I want to run essential loads such as well pumps (2), oil furnaces (2), a refrigerator, and some lighting. I am also interested in being able to deliver power to some other loads (an internet modem, and one or more computers, all of which are buffered by Uninterruptible Power Supplies, and possibly an electric [induction] cooktop, as natural-gas service is not available here. (Propane is available, of course, but I'd prefer not to use propane.)
What loads I will be able to power will depend, of course, on the output available from the generator. The latter will depend upon the horsepower rating of the tractor's motor, the efficiency of the PTO, and the efficiency of the generator.
From the Ventrac web site, I have downloaded the Owner's Manual for the 4500Y and the HG150, and also the Owner's Manual for the Voltmaster Aeries AB, AR, and EC Two-Bearing Generators. I downloaded these to become familiar with them, and to see if there was a listing for the overall conversion efficiency, or the individual efficiences.
I'm not sure which model of Voltmaster generator the HG150 employs. Unless I have overlooked something, I do not not see a precise specification in the HG150 owner's manual. I suspect it is of the type AR, but the only model of the type AR listed at the Voltmaster web site, the AR100, has power ratings that do not match those of the HG150. The AR100 has ratings that are about one-third less (10 kW peak, 9.5 kW continuous for the AR100 vs. 15 kW peak, 12.5 kW continuous for the HG150).
According to p. 4 of the Voltmaster Owner's Manual available via the Ventrac web site, the AR100 requires 18 HP of mechanical driving power to achieve its rated output (again, 10 kW peak, 9.5 kW continuous). I suspect that the available PTO output of the Model 4500Y is in that ballpark.
If so, and if the conversion efficiency of the HG150 is the same as that of the Voltmaster AR100, then the Model HG150 would seemingly be unable to achieve its rated output power (15 kW peak, 12.5 kW continuous) when driven by the Model 4500Y. If that is the case, it's not the End of the World As We Know It. It's simply a matter of me determining how many "convenience" loads I will be able to power, and moving the appropriate circuits to a third circuit-breaker panel.

Thanks in advance for any insights.
