Generac GP18000EFI

The generator is being used to charge batteries and run a small cottage at the same time. No complaints about weight and size as it's expected. It fired right up and started going to work. The only problem we have encountered is the 30AMP breaker keeps tripping if we run small window air conditioners (5AMP) or anything at 1,500 watts=12.5AMPs for a brief 5 min. The offgrid includes four banks of 48V AGM batteries. We set the Magnum inverter down to 80% and AMPs down to 38. This seems to be helping but we can't put a larger load on. So we installing a 50AMP plug on the house with a cut off and bipass, essentially we will be running the 30AMP plug to charge the batteries and the 50AMP to run the house. Typical charge on those batteries is around 4 hours. If you plug an appliance at 12.5 AMPs direct to the generator - there's no difference in load sound. As a building contractor we designed our own off grid system and will be writing a book with as much detail as possible.

Just what I needed

[This review was collected as part of a promotion.] I have used this generator a few times since getting it and I have been extremely happy with the product. No issues or concerns with starting and it provided more than enough power to supply my home during the outage.

Better then my first Generac

I already owned a 5kv Generac and was extremely happy with it. A few weeks ago my daughter lost power due to storms and was told it could be 5 days until power returned. I loaded my 5kw on trailer and connected to power her frig, furnace, and a few lights. Generator worked great as always, and saved all food, kept house heated. I then decided why haul back and forth, since it worked so well at her house I'd leave it there and buy myself this new 6500E. Now I know we both will never be w/o power again what ever mother nature throws at us and I will not have to "share."

Performance is good

I have the 7000E and from what I can see other than the covered outlets and uni handle bar, it is the same model? The only issue I have so far with the generator is that the on/off fuel valve tab broke on me when I was turning it on. Now I use a tiny vice grip to turn the valve. Hard to find what part number I need for the generator b/c I can't find a parts list but all and all a solid generator.

It will definitely work for you.

I had this delivered to the house. The packaging was very good. No damage. I did all the assembly within a half hour. Filled it with oil and put some gas into the tank. I used the electric start and it started up with no problems. Temp outside was less than 5 F. I bought the electric start only for my wife so she could start it up if I wasn't home. The manual provides all information needed to star and maintain the unit.

Just what we needed for small home back up

This is just what we needed for a back up generator. We live in a very wooded rural area and power outages in the winter can be brutal when temps drop below minus 20. The GP6500 is perfect because it is portable and reliable. Now when we lose power during a winter storm we grab the generator out of the garage and plug it into the transfer switch and it keeps us and our house from freezing.

Reliable power.

Purchased the E7500 in 2015 during a week long power outage from a wind storm. It powered my furnace, lights, microwave, Keurig and toaster oven. It was 11 degrees F and very windy. I have used it several times since for minor projects. It starts every time with both battery and pull cord. It's on its second spark plug and battery. Love this generator.

Let me down during the storm

Helene came through, purchased this generator and it ran for less that 25 hours and wouldn't keep running. Took it to the local services center and had to pay $40 for them to evaluate it for repair. Makes me leery of investing in a whole home system through generac.

Generac generator

[This review was collected as part of a promotion.] This Generac generator is a tri fuel generator i like that you can use gasoline or propane or natural gas it also has a CO sensor that shuts off the generator if it detects carbon monoxide you can start it with a push button or a pull rope it is not very noisy it is easy to assemble and easily rolls where ever you need it

Should do the job easily

I bought it for emergency power for when our tree lined street takes out the power lines. I've only run it for a few minutes so far, to test the breaker box connection. It ran the well pump, furnace, and a few lights without issue. There will be enough power in reserve to keep us comfortable if we have another snow disaster this winter.
