Q: How long will it would it run on half a load on 150 gallons of propane?

by Micheal from Texas on July 18, 2014

A: Per the specification sheet the fuel consumption rate at 50% load is 4.07 Gallons per Hour. This would equal to 97.68 Gallons per Day (4.07 x 24 hours). This would give you an estimated 1.53 total days.

The issue with this is that you cannot use a 150 gallon propane tank with a generator this size because this tank does not produce enough BTU output capacity for the generator to start. All generators must start at full load output and a this 45kW unit needs 726,000 BTU's and the 150 gallon tank only produces 293,760 BTU's which is nowhere near enough to even start this unit.

The minimum size LP tank recommended for a generator of this size would be 1000 gallons.

Q: Will this unit work with the 25kW liquid cooled generator?
by Jon from Texas on February 08, 2011

A: The Advanced Wireless Monitor will work with Generac Air Cooled and Liquid Cooled standby models that have the Nexus controller.

There is a Harness Adapter required for 22 - 60kW Liquid Cooled models.

My Story
Searched and debated the expense of installing a whole house generator. I live in the woods literally! I have had the electricity off for up to 3+ days and that was not a fun experience. But decided to buy one that would meet all the comfort needs. Guess what? A few short months later a snow/ice storm hit. Within seconds my Generac powered up without a blink. I was in the shower and didn't even know it kicked on except the TV was resetting itself with the satellite.

No Power Mean No Well Pump
After fires swept south of my land and the power companies started turning off power to grids, we decided the time was now to install a back up generator. Selected the 45 kW Generac for whole house and shop. We checked around and got pricing from several contractors and EGD had the best price. Delivery was as promised and set up was simple if you have the equipment to lift this size of a generator. I had everything in place and ready to go when the electrician arrived to finish.
Pros: Durable, Quiet, Reliable, High Quality
