Additional Features
Improved stub ups and electrical connection access decrease installation costs. All connections are dual conductor rated, and the implementation of quick connects for the control wires, completely eliminates the need for crimping or lugging.

Rated 5 out of 5 by from Worth every penny Upgraded from 20KW, needing to handle more load in the house. This new generator is a monster. You can not hear it inside (it is near the master bedroom. Switch over is almost to fast to notice. WIFI feature is great. Our installation was painless ( and fun to watch).

Rated 5 out of 5 by from Architect From the sales visit from Matthew to the follow up from Tyler and the excellent crew of 6 men, the entire process has been professional and just downright super. We had a 38KW unit installed. The crew showed up around 10:30 and completed all the work at 7:00 p.m. It was a great experience. It's wonderful to know that there are companies out there who have pride in their work and train their employees well. Thank you.

Rated 5 out of 5 by from Product Is Excellent Prior to purchasing I spent some time evaluating gen set units for installations in our family properties. My research over two years and 40+ years with propulsion, engines and electrical generation led me to Generac. I am completely satisfied with the unit. The system is only as good as the installation. The installer Ready Power was beyond excellent. Standards that meet National Electrical Codes and Piping Code standards. The engine is one part of a emergency power system you select. Choosing the correct installer will ensure that you have a reliable and safe system that will last a long time if properly exercised and properly maintained.

Rated 5 out of 5 by from This size generac is phenomenal! We have had friends that have installed smaller systems and they do not power the entire home. I believe that if you want to have backup power, it should cover your pool, home, AC, heat, and all other necessities of our daily lives. It will make a world of difference when you lose power next.

Rated 4 out of 5 by from Wrong nozzle, proper tool not included The unit was shipped with natural gas instead of desired propane nozzle. Changing required significant disassembly. Instructions said to remove nozzle with flat blade screwdriver but nobody has a screwdriver that is 5/8 in wide. I literally had to fabricate a tool to remove and install the nozzles. Installer knew nothing about this so it was fortunate I had a plasma table and proper material to make a big enough tool. What do you expect your installers to do without the right tool?
