Good basic generator for infrequent backup of critical loads

I don't lose power often but do not want to risk a basement flooding or no heat in winter or fridge full of spoiled food, etc, so this was well worth it to me. I am moderately handy and did the installation myself (after getting building permit). One aspect that confused me was the transfer switch manual states that power and control wires to the generator must be in different conduits and the diagrams all indicate this, however the corepower unit is clearly designed to run all in one conduit (the manual pictures show this plus there is only one knockout in the generator electrical interface. In the end I figured the transfer switch manual was written to accomodate larger generators as well and installed the wiring in one conduit (10ga thhn for pwr and 14ga thhn for control). I ran 8ga thhn from the 50A bkr in the utility panel. I left the house (load) grounds and neutrals in the main panel and just ran 12ga thhn from the xfer switch load outputs to a wire nut connection to the hot wire in the main panel (important that the hot wires are just passing through the utility panel, not terminated anywhere in there). A warning sticker came with the transfer switch to put on the utility panel to warn about the presence of feed-through hot wires from the transfer switch. So far i'm happy with the product. I like that the xfer switch that comes with this unit has you use your own wire (no harness) however I they should be more specific in the installation manual in the areas I mentioned. Also note that this engine is more basic than the guardian series (OHV vs OHVI), and therefore may not last as long. Also the corepower has less clean power regulation. If you are expecting to lose power a lot or are powering lots of electronics you should consider the guardian series, otherwise the corepower is a great option.

Just right for home backup and almost a drop in installation

For my 3000sq ft home this is a perfect fit. Using for backup to cover refridgerator, well pump, furnace, network and odds and ends like garage door. With the transfer switch already supplied and matched to the 7KW generator, and great instructions, this is an easy install. Self install is not for everyone one, but if you have previous experience with doing, and the knowledge to do, correct plumbing and electrical, then expect to save at least $1000 on your install. Get your work inspected as you go, research your local codes and you can enjoy not only putting this together, but having the finished backup power you need. I had a 15KW Generac on my last, larger home, and it worked flawlessly when I needed it on several occasions, and was easy maintenace. Just looking this CorePower 7KW over I can see it has the same easy service and is well designed. Sound level is very reasonable given what it does. = The small footprint is great and it looks fine next to the central air outside unit. Wife thought a generator outside this home would look bad but changed her mind when she saw it in place. We definitely would do this again right now if it disappeared!

Great product

We have lost power 13 times this year since April ranging from 2 hours to 7 days. We lost all of our frozen food during the 7 days, At that point I ordered this unit and then took about a week installing it myself. The instructions are good and I also looked up more info on line. If you are comfortable with plumbing and electrical wiring this is not a hard installation. Since I got this up and running we have had 2 more outages and this unit fires up and has us back in power in one minute. Amazing. Also I like the fact that once a week it starts up and exercises itself so that when we need it it is ready. One thing I would advise everyone is to buy a multi meter that can measure Hz/Duty cycle as this will assure you that your generator is "making electricity" as good or better than the power company.

Great value, does not have a negative effect on landscape.

Great piece of mind

We bought the core power after reviewing the competitions products based on the quality of the engineering and innovations. We have a 1400 SQFT house and the core power will power the refrigerator, water pump, oilfurnace, gas stove, kitchen lights, microwave, upstairs bedroom and living room TV. The cost of the core power is not the only cost however, so price out your electrician and gas company hook up. The electrician cost us $1500, the gas company hook up cost $700, Battery $100 & permits & inspections cost $300. You may have to build a concrete pad and dig a trench to run the utilities. Make sure you hire an electrician who is GENERAC trained in the installation. You will need to site the generator so that it meets local requirements. We installed a 100gallon LP tank --- at half power you can go for at least 3 to 5 days Once it is in and working you will not have that panic feeling when they say a big storm is on the way

Uneven power to computer is a real concern

My house is small, so I didn't need a large generator. This unit powers most items in the house, but not central a/c or microwave. I have a home-based business so having a generator for back-up power was important. When the generator was tested after installation, it pulsed uneven power to my computer equipment and very much had the potential of doing damage. The electrician had to buy & install a power conditioner so that the system is usable. Same electrician had massive issues with the installation, including 4 failed inspections. Though he had a lot of experience w/Generac system installations in general, this was the first PowerCore he installed, and apparently it posed a lot of problems for him. The generator goes through it's weekly test-run without any issues, but I've not had a real power outage yet to report on a real-life episode.

One big initial glitch...

First the glitch: within a month of our installation (November '11), the starter motor seized. Of course without an easy way to see the control panel warning lights, it took a couple/three weeks before we noticed a problem, and then a month between the tech diagnosis and the new part arrival and installation. So we were generator-less for close to 2 months altogether. Since the repair, we have not had a power failure to test it out fully, but the weekly exercise has gone off without hitch (5 mos now). The repair tech was pleasant, if somewhat unfamiliar with the unit. But he was walked through the diagnosis by Generac so that's all the really matters. Assuming it holds together for the long term, the features, capacity and price point make it a great little unit. I have suggested this generator to friends and family.

Home Owner + They make it simplely stupid !

You can't fix stupid ! So they took that part out ! This is as close as you get to Plug and Play ! You can't go wrong with this unit. It will power up enough stuff in your house to keep you warm and comfortable in the worst of times. I just installed it myself. I covered the "Heat" the "Frig" the "Freezer" the "Kitchen" the "TV" the "Lights" and still had to add two more ! Remember, it's for a short period, every few years the lights go out ! Wiring was very easy, simple diagrams, and basic wiring to the panel. Make sure you have a few pro's on speed dial to back you up if your not sure. They made this "GI" proof. So you know it's good. I'll post on You tube later. One Con !~ If the unit is sent to the North, it should include the Cold weather kit and the wiring diagram.

Good product for the price. Generac promotes quality.Definitely Recommend!

Unit was purchased to back-up sump pump. We had finished our basement and did not want to lose investment. Added protection included refrigerators,some lights and microwave. A few days after being installed we lost power for an extended period of time. The unit performed flawlessly. Since then it runs programmed testing every week as set. Unit has small foot print and very neat appearance.Noise level is not bad. Neighbors are inquiring about the unit and it's performance. They seem very interested. Changing oil can be performed easily. Peace of mind is worth the reasonable cost.Had it installed and it only took a few hours including the tie-in to the LP tank. Recommend! Generac stood behind some minor problems like true professionals.

Good product / Good decision

I live in an area with high water table. I was thinking of getting a portable 6000 watt generator incase of power outage for two sump pit pumps. I have marine battery backup sump pumps but the last outage lasted 5 hours. I decided to have a permanent backup system incase I was gone for a day or more. The professional installer liked the transfer switch and generator unit. The weekly cycle check comes occurs on schedule. The Generator sound is like a lawn mower outside. Electric power has only went out once in my area since the installation and the unit kicked on and the areas of house with dedicated circuits worked. With the smaller unit the only big decision is which house circuits will have the priority.
