Rated 5 out of 5 by from Installation just completed We got the 24KW. It's beautiful and worked like a charm during the demonstration. It feels good to have peace of mind and not have to worry about storm season.

Rated 5 out of 5 by from Just Installed VERY Happy! Generac 24KW ATS I am so glad that I had my generator installed this year because the 24KW unit was available. I took advantage of the MobileLink WiFi which is great because with any status change, emails are sent to me and my dealer. Peace of mind knowing the unit is operational and ready! The Tank Utility Monitor is a real plus because at a glance of my phone, I know the fuel level of my propane tank. Sweet! The Smart Management Modules really are smart making whole house transfer a simple hands off operation.

Rated 3 out of 5 by from 22k generator review We had many outages and needed a generator. It took 11 months to finally get it installed and today we had an outage. After starting we got an alert for a low battery after only having it in place for 6 weeks. Installed did say he would email maintanence plans, but the email never arrived. Been such a headache, wish we never got this

Rated 3 out of 5 by from Poor installation Instructions and not all systems work The installation instruction jump around . 1. Should list all required downloads/ apps in one location. 2. Not have separate little instruction in odd pamphlet's or in conctient locations #. After have the PWRView installed, I found that you had to download another app. This app would not accept the same app as the other apps for this generator and would not send me an email link to reset. I paid the electrician money to stand around with the generator running only to bedead ended, The PWRView app would not let me register

Rated 5 out of 5 by from Generic has a dependable product After many power outages in 2020 we decided to purchase a generator. We chose Metro Electric to install it because they had the best presentation. It was installed on May 26, 2021. It was a rainy day but the electrician and plumber had tent coverings so they could proceed as planned. When they came into the house they had foot coverings so as not to track in any dirt. We felt they were very professional and knowledgeable. When the electrician was done, he came in to explain the Operating and Maintenance Binder. It said our generator would come on every Wednesday at 12 p.m. and on 6-2-21 it came on at 12 p.m. And on 6-9-21 we had a very short power outage in the morning and the generator immediately came on and then again at 12p.m. We are very pleased with the installation and especially the power outage start. That was great evidence that our system was working.

Rated 5 out of 5 by from Convenient and Reliable After spending a week without power in GA from an unprecedented storm then coming back to FL and having the power out due to a hurricane, we decided to invest in a Generac. We had done our research and the Generac had the best reviews plus we knew several friend with different brands. The convenience is unbeatable and the security it provides our family knowing we will not be spending another night in darkness is tremendous. The professionalism of the company we purchased from was unmatched in this day and age and I not only recommend Generac but I also recommend RAJ Electric in Jupiter, FL.

Rated 5 out of 5 by from Great Product - Easy Install We had Switch Electric, LLC perform the installation. They came highly recommended and I can see why. The installation went flawlessly, their explanation of the system was easy to understand and the product works incredibly well. We typically lose power here in our area at least three to four times per year and were tired of hooking up a manual generator to the house during those windy/rainy times. Thank goodness we now have the peace of mind that it will happen automatically.
