Скачать или смотреть 6.2 liter V8 Backup power. Kohler 48KW LP Gas (Propane) Generator 48RCLC

Tour (unboxing) of a new 6.2 liter V8 48KW backup generator. This generator runs its massive GM V8 engine at a quiet 1800 RPM. Kohler 48KW LP Gas (Propane) Generator 48RCLC
Also unboxing of the two automatic transfer switches:
Kohler RDT-CFNC-200ASE
Kohler RXT -JFNC-0200ASE
These switches both have Service Disconnect functionality.

I got a question about propane consumption and propane tank size. Here is my reply:

In cold weather, a large generator can consume propane faster than the propane can evaporate inside the tank.

At full power, this generator uses 9.3 cubic meters of propane per hour - at any temperature below 20°F a single 500-gallon tank can not provide enough propane vapor.

Here is how I studied the problem in a spreadsheet:

One solution is to use a larger tank, and another is to somehow keep the tank warm. Apparently, this is why some tanks are buried underground. There are also electric heating blankets: https://amzn.to/3CIdeey

Our solution will be to use 2x 500 gallon (400 useable) tanks, for 1000 gallons (800 useable) total. If the tanks are reasonably full, we should be able to use full power down to 0°F and should be able to use 50% power down to -10°F

This generator is way overkill for our needs, so we do not expect it to run at more than 50% power.

Our runtime from a full tank at 100% power should be 88 hours, at 50% it should be 167 hours, which is a full week, running 24 hours a day. In real life, we would probably shut it off at night in all but the worst weather.
