Default Home Stanby Generater System

I figure alot of you Florida/Coastal folks have them and are knowledgable about them.

If you do, can you tell me what I need to know about them/installation?

My friend has an industrial supply company. He bought 10 65kw John Deere diesel powered units with Baldor alternators + a 300 amp Auto Transfer Switch. No fuel tank. He will sell me one for 12k.
I have to install. This sounds good to me, I think!!!!!!!!!

What BB wrote.

Mines running right now up North. It seems that this storm made a real mess out of the area after I left yesterday morning. Lines down all over and no crews working because the town is very small. Power was lost 20 hours ago.

I have a LP fired Kohler 11kw with the auto transfer switch. It's about as quiet as a vacuum cleaner .

The installation is a little involved but they make a circut breaker panel that's an option to finish off the install. It really needs to be done by a pro. Check the systems out on line.

I see you posted while I was writing. What are you going to do with the rest of that power? Feed the hood?

Thanks

I know I want/need one. It's just do I want that 65k unit? Diesel? 12,000$ ?
I have lost electricity for 14 and 10 day periods over the last 4 years plus many 1 to 3 day periods.
I live on the end of the system on a farm.

I agree, if you are installing this at your home. I doubt that you would need half of that to run everything at your home at the same time.

Know what you are saying. What's a good deal on a unit if you don't need it? I think I will have to spend 14k to 16k, installed, for a watered cooled 40k unit. I have propane tank, 500gal, already.

I have a Generac/Guardian 15Kw running on Natty Gas. Comes with the transfer switch. All very easy to install and run. When I got back to the house after Katrina, I was living well compared to others. I can't complain about the unit except for the saltwater spray from the storm is rusting the steel case that the generator sits in. But since I bought my unit, they have come out with an 16Kw unit that comes in an aluminum case. Very nice.

I keep three 110V window AC units in my attic for post hurricane living. Chances are in a major storm, your AC condensers will be knocked off their pads and ruined. The window AC units run great on the outlets that you have hooked to the generator and make life goooood! THe standby generator is the best $4000 I spent in building my house.

Do you run a set amount of circuits? If so, do you wish you had a whole house? If you did a whole house, what KW would you buy? Air or Liquid cooled?

What are you trying to run? That's the first thing you need to determine. The larger the unit, the more fuel it burns. Think very carefully over that statement.

I have room to spare on 11kw. Master bedroom and bath is live, guest room has light as does the guest bath. Downstairs the kitchen cooktop and vent hood are live, 1 undercounter plug strip, and the fridge. Table lamps and TV in the LR. (we scene lighted the house in the major living areas. These have no lighting except normal table lamps) The powder room on the first floor has light and vent. The basement has some lighting, well pump, full heating system is powered and the alarm system. Throughout the house are live wall and floor outlets for ???? Outside the down lamps on the porch are live along with the garage door openers, door lights, and basic lighting inside the garage. It's detached.

I will add more to the load in time. At present the genset is to prevent a freeze up and prevent the food (beer) from getting warm.

Retail was 2000 for the transfer switch and 5000 for the genset. Misc labor, copper wire, disconnect, and conduit adds maybe 1000. This was all done while the house was being built so it's hard to track. Also I didn't pay anywhere near MSRP for anything. I have friends who saved me allot of money.

MYGAL- am currently working on getting a 100kw unit designed and installed inside a clients property - a Baldor unit. As I am finding out a big unit - the 65kw unit you have access to is big - if its going to be inside needs lots of cooling air and exhaust air - to the tune of 18 s.f. of louvers each for the 100kw unit I'm working with. This unit will run an entire property (large house, carriage house with ac and all loads tied to it, 600 amp service). You need to figure out if you need to have 65kw capacity casue the price of the unit might not be such a great deal if it costs a fortune to have it installed and set up properly if you dont need all that juice. We're using the combined services of an electrician, and HVAC engineer plus me to figure it all out. Most other propertys can get by fine with 10-20 kw which is a lot easier to deal with.

Thanks Mymojo

I'm real torn on this and told my friend we will discuss the sell today since I have a local company who sells propane/water cooled units up to 50kw coming by tommorrow, they do the installation.

I have 4 heat pumps, 2 small, 1 medeium, 1 large. Well, water heater, 5- 1500 watt bathroom heaters, 3 fridges plus rest of the house. Two 200 amp service panels.

Keep in mind, $12,000, 65kw!!!! Installation/fuel tank extra. Not sure what to do.

By the way, this is a free standing unit with aluminum enclosure + 300 amp ATS.

I have a 12kw Briggs-Stratton/Cutler-Hammer unit that runs on either propane or natural gas. At the time of purchase it was the largest one that would run off of the low pressure gas meter that is standard on most houses in this area. I would have needed a high flow gas meter to go larger. I ran a 4 ton a/c unit, 2 fridge/freezers, an upright freezer and just about all the lights on my house for close to two weeks for Katrina. I have it on a sub panel, which will not allow me to overload it. It has a weekly run cycle, which keeps the battery charged and has automatic startup when utility power is loss. The unit is air cooled, so oil changes are more frequent than liquid cooled. I run synthetic oil, which was changed @75 hour intervals and the filter was changed every other oil change. The unit with transfer switch ran about 4k in 2004.

My gas bill was close to $400.00 that month,whereas, it's usually $40-$50, but I wasn't lugging fuel back and forth... Not that there was any available in the area. It ran 24/7 other than for maintenance shut-downs. We were running 3 businesses, so we needed power. My brother had a 10kw generac gasoline model that was burning close to 10 gallons a night for reference. Good thing the boats were full of fuel.

It may not be as quiet as the liquid cooled models, but even with the side panel removed(concerned about heat in mid Sept.) you could not here it inside the house.

The below site is a basic checklist to see how much power you will need. The other site is for the model that I have. They now make a 15kw that will run on low pressure. I bought it locally, not from Northern, but they have the specs.

I have 10 circuits hooked up. 8 are 110V and 2 are 220V (the sewer lift pump and a 4 ton AC). That is a bit less than 1/2 of my downstairs. Which is just fine. The kitchen, laundry, and living room are hooked up. The master bedroom isn't really a priority to me. I put 2 window units in there on heavy duty ext. cords and a small lamp for nights following Katrina. The ability to have the kitchen and laundry (wash clothes) are most important to me. The AC for the litchen/living room side is the one hooked to the generator. Heck, if there is no damage to the AC condenser following a storm, we can sleep on the couch. Either way, I don't need the whole house hooked up. We can be very comfortable with just a little inconvenience (its not healthy for the generator to run the AC and washing machine at the same time). If I were to hook up the whole house, I'd need at least 40Kw liquid cooled unit ($$$$$)... after all I have over 15 tons of AC in the house!

For a long power outtage like the one following Katrina (4 weeks)... I only ran the stand by generator from dusk to dawn. During the day I opened the house up and let the breeze blow through and ran a 2Kw Honda (Bought on a THT powerbuy) to keep the fridge and freezer cool. A night of natural gas costs about $20 (worth every penny)... a daytime of the Honda costs about $2. And I was not sitting down relaxing in the house anyway (gutting carpet, baseboards, and sheetrock).

In the event that its just a minor storm or power outtage and the cable still works... I can sit at my kitchen counter and watch TV and read my boating forums while everyone else is sweating in the dark. Hehe!

I'm with you on that but I got 4 women in this house plus an attached apartment an old local lady rents from me @ 200/month the last 12 years, no price increase because she can't afford it . That's 1100 sq. ft. and it uses $350/mo in energy alone.

I think I will pass on the big 65kw diesel unit now because I don't think I know what I'm doing.
I do believe I will regret it later though.

Do you have one or two meters? And are they next to one another?

Anyway, call your power company and they can tell you what your peak usage was over the last year. That should give your EE a good idea of what size you will need.

Also, if you go with a natural gas unit make sure that they quote you the specs when it runs on natural gas. For the same output the natural gas unit is usually larger than a diesel unit or if it is a dual fuel unit the output on natural gas is lower.

And don't forget the battery charger and block heater. If your power outages are cold weather related these will help keep you in business.
