Stator shorted out at 103 hours
Product Review Rating: 1/5
Posted by Unknown on Oct 17, 2020
Unit was installed in 2012 and only ran for its weekly cycling.
Failed at 103 hours of run time, just after warranty expired.
Unit is junk and Service Center said they need to be paid to remove it.

The way to go

We're off-grid. The portable generators are for survival. The 14kw resa is the way to go for dependable living. Very quiet and well made...We love it and can monitor and control it when we are away! AP's price cannot be beat and it was here i just days not weeks!!!!!

Generator is working great
Product Review Rating: 4/5
Posted by Wes on Jan 17, 2018
I received the generator in good time and droppec right off in my driveway. It took a little time to get it installed into my totally off grid system but it started right up when I got it done. With our 20 solar panels we still need to run the generator for a few hours every 4 to 5 days to keep the batteries charged in these low light winter days. I've run the generator for 5 cycles now and it works great and is very quiet. I can't speak to longevity yet but i am very satisfied.

Prefer Koehler to Generac
Product Review Rating: 5/5
Posted by Rebecca on Jan 11, 2018
We live off grid completely, with two trackers and 14 solar panels that take use completely through seven months and our LP Koehler 14kw to supplement solar or completely for the remaining months. The two wire start made installation quick and easy. We replaced our LP Generac 15kw with the Koehler. Though it is less kw produced, it uses a less LP and is more than enough power for our 2200sq.ft. house. AP was the cheapest, with free delivery and a battery. They will always be my first place to look for any kind of product that they sell.

Absolutely reliable unit
Product Review Rating: 5/5
Posted by Jim Baumann on Oct 25, 2017
Bought an identical generator for my off-the-grid electrical system 8 years ago. It had over 10,000 hard hours on it, the motor was weak but the generator head was still good. It could have been rebuilt but we decided to replace it with a new one. Absolutely satisfied with the unit, AP was the cheapest around with free shipping, delivered the unit in record time. Very satisfied.

Nice Generator
Product Review Rating: 5/5
Posted by Eric on Sep 28, 2017
I recently purchased this generator for my new off-grid solar system. The system is not completely installed yet so I cannot comment on the long term reliability of the Kohler but I have installed the generator and it started right up and seems to be running great. AP Electric shipped it quickly and the generator was packaged nicely. The battery, however, was just wrapped to the top of the generator box. Probably could have been packed a bit better.
I think the generator is going to serve me well.

Great Purchase
Product Review Rating: 5/5

This Kohler 14kw home standby generator has been a great purchase for me. AP Electric was fantastic through the entire sales process. I did not even know what size I needed when I called. They were not pushy at all. They did not push one brand over another they were just concerned that I get the right one for my application. I probably talked to them 5 times over a 2 week period. Always patient and really wanted to educate me on the differences between brands. I ordered and it arrived 2 days later. They even gave me a couple of recommendations on installers in my area. Installation went off without a hitch. Looks and runs like it should. One 2 hour outage since installation and the generator performed perfectly. Highly recommend both Kohler and AP Electric if you need a home standby generator.

Purchase experience exceeded all expectations. AP Electric sales associates were helpful, informative and communicated all aspects of purchase & great follow up. We are off grid in the Sonoma wine country so back-up generator a necessity. Highly recommend, very professional company with the best prices.

Prompt online service and delivery. Researched for about a year so I could replace my Sentinel 9 Superior generator. The Kohler 14000 was the best for the money.

I would recommend AP to friends and family in a heartbeat.

Unbelievable experience. To have a 14 kW whole house generator, transfer switch and battery ordered on a Thursday and delivered the following Monday with no problems and have everything work when installed is nothing short of incredible.

I ordered this generator online because I was having trouble finding a reputable dealer in my area. I ordered it on a Monday evening and it was delivered to my driveway that Saturday. Transfer switch is back order till the end of December (at the earliest) so I haven't been able to start it yet....
