Q: Several questions actually. Looking at whole house generators. I have 400 amp service and want to power entire house. LP is my preferred option. What size LP tank is recommended for a 38 kw? Next, Automatic Transfer Switches with Service disconnect, I know that I need this as well, but what about a Load Control Module as well? Do they work with each other or are they performing the same function?
by Michael Mcnulty from Virginia on December 13, 2013

A: The Generac 36kW unit uses 5.5 Gal/HR at full load and 3.0 Gal/Hr at half load. Based on half load use you would use 72 gallons in a 24 hour time period. So depending on how much backup time you require would determine the tank size along with the ambient temperature in your area.

A 1000 gallon tank has 600 usable gallons with the BTU output varying depending on temperature. A 1000 Gallon tank BTU/HR output capacity based on 40 degrees F is 1,416,960 BTU/HR and a 36kW, at start-up, requires 500,00 BTU/HR and a tanks BTU content when the temperature is at 0 degrees F is 472,320 BTU/HR. To properly size a generator to your fuel source you need to size it to it full load start-up BTU/HR requirements.

The matching whole house transfer switch would need to be rated at 400A to match your incoming service with the recommended model being RTSY400A3......

Link - Model RTSY400A3

The transfer switch comes ready to handle 2 AC unit without any additional hardware. However, you can do up to 4 more large loads with the use of the Load Control Modules (PMM). The first PMM needs to be model 6199 which includes the 24V DC starting kit (required) and then the other 3 can be model 6186.....

Q: What size gas line do I need to install this unit? I am building a house and want to prepare for this generator.
by Jake Z. from Texas on November 07, 2013

A: Pipe sizing is based on the distance from the fuel source.....

QT03624ANAX Requirements:

Natural Gas (NG):

3/4 Inch: Cannot Use
1 Inch: Cannot Use
1-1/4 Inch: Max Distance 35 Feet
1-1/2 Inch: Max Distance 95 Feet
2 Inch: Max Distance 370 Feet

Liquid Propane Vapor (LP):

3/4 Inch: Cannot Use
1 Inch: Max Distance 20 Feet
1-1/4 Inch: Max Distance 125 Feet
1-1/2 Inch: Max Distance 290 Feet
2 Inch: Max Distance 1030 Feet

Add 2.5ft per any bend, tee or angle in the pipe to the overall distance.

Gas Pipe sizing is one of the most commonly made mistakes. A properly sized gas pipe is critical to the proper operation of the generator. The generator inlet size has no bearing on the proper gas pipe size.

Q: I'm going to build a house in the spring of 2013 and I want to have a standby generator installed when the house is built.

What would be the best size generator? I plan on having a geothermal heating/ac system and the house will be all electric.

by Dan from Kansas on August 06, 2012

A: Thank you for visiting Electric Generators Direct. In regards to your question, the generator size is determined by the starting amperage load of the equipment you are planning on powering when you lose power.

The starting amperage load will be much larger than the running load and proper calculations need to be done to properly size a unit.

We recommend having a certified electrician do your wattage calculations as every home is different.

The electrician would calculate with the following formula to properly size the generator which should be sized at 80% of its running capacity to allow enough flexibility to handle large intermittent loads and still keep voltage output at proper levels.

(Starting Amps x Volts = Watts)

Note: Geo-Thermal systems can require a tremendous amount of starting current and all calculations should be done onsite professionally.

Q: I am looking at the Generac QuietSource Series™ 36 kW Standby Power Generator (Premium-Grade)

What's installation going to run me?

Thanks

by Randy Meyers from Maryland on June 30, 2012

A: Unfortunately we do not work directly with installers so we do not know what the pricing could be. I can also be determined by your specific installation needs and what your local code requirements are.

With these systems it is best to have a Generac installer and you can find one from the following link....also try to get a minimum of 3 quotes due to the ever changing installation prices.

Q: When the generator runs on the time you set once a week, does it actually transfer power to your house or does it just run with out transferring power?
by R. SMITH from Louisiana on February 10, 2011

A: The unit is just going to exercise without load. This would not transfer any power to the house on the exercise cycle.

The Generac QuietSource Series 36 kilowatt standby generator is ALMOST the perfect whole house generator.

Why only almost?

The larger, more expensive 48 kilowatt version produces a whopping 200-amps of electricity at 240 volts. Basically, it will replace every single amp capable of being supplied by the utility company.

The 36 kilowatt version generates only 150-amps or roughly 75% of the 200-amps coming through your electrical panel.

But, here's the bonus. You rarely use all... more

Strong And Quiet
Got this unit to replace on older version that salt air from Key West had destroyed. Much nicer built than the older units, but everything other than the fuel line was in the same place as the older unit. That made installation easy. Started right up the first time. Even with the cover off it is very quite. With the covers in place it's hardly heard from 20 feet away. Can carry on a conversation standing right next to it. Will have to see how the new cabinet holds up to the Key's air.
Pros: Easy To Use, Quiet, Price, High Quality
Cons: Heavy

"Good buying. Ordered it and had it delivered to a different location other than the billing location. A remote location at that. No problems getting it shipped and only cost $50 to have it shipped there for a 1500lbs package is great. Will buy again."

Excellent
I own a 45kw Generac at my home in Florida. This 36kw is for my summer home on Smith Mt. Lake, Va. My Generac @ my Florida house is seven years old and doesn't have the aluminum housing or the 1800 rpm engine.

I really like how quiet this new Generac is during exercise you can barely hear it standing on the upper deck.
Pros: Features, Easy To Use, Quiet, Price

Was This Part Needed?
I purchased a 36KW Generac Quietsource and the wireless monitor from EGD.

I also bought this adapter harness, but could not figure out where to connect it. The documentation was not clear, the photos of the genset were not similar to my 36KW, and the plug that was shown in one photo does not match up to the harness.

I was able to easily plug in the wireless monitor with the cable that came with it. It easily reached from the Nexus controller to the knockout on the side of the genset... more
