Overview generac 6438.
Generac 11kw generator propane consumption.
When the generator is not running you have static liquid in the tank with a vapour space above it.
It is also a vapourizer.
Generac also offers a wide range of 50hz home backup generators.
Generac generator fuel consumption rates.
While jeff s math is correct as far as consumption there are some properties of propane that come into play here.
A home backup generator delivers power directly to your home s electrical system backing up your entire home or just the most essential items.
First you need to understand how a propane container functions.
Lp consumption 50 load 1 18 gallons hr btu.
It is not just a storage device.

Again these are all rough estimates and a true estimate of generator fuel.
The generac 6438 11kw air cooled generator is considered one of the best for the homeowner with average electricity consumption.
The biggest mistake most experts make in opinionating that a propane or natural gas generator will lose power is based solely on these figures and not on any data.

The minimum tank size recommendation is 250 gallons per generac due to the starting btu hr requirement of the generator and the overall run time.
Propane only has about 10 less btu content than gasoline gallon to gallon so the estimate used by yamaha for gasoline consumption will be very close for propane if not exact.
It runs on natural gas or liquid propane lp fuel and sits outside just like a central air conditioning unit.
Let s say 20kw in this example a propane generator may use around 2 3 gallons hour.
The 11kw unit has the following fuel consumption rate found in the specs tab on the generator product page.
So if you have a 500 gallon tank which can only be filled to 400 gallons then a full tank would last you around 6 to 7 days.
Generac home generator fuel consumption rates will vary depending on the size and model of the generator and the load it is under.
