Customer Reviews for Generac Protector 38,000-Watt 120-Volt / 240-Volt Single-Phase Liquid-Cooled Whole House Generator

What I like best about my Generac generator is the hi-low feature and easy transfer to the house

Very satisified with the 38KW generator bought - and was amazed on how "quiet" it is when turned on (the noise level is way lower than for smaler generators).

We love this Generac generator. This unit is model RG03824ANAX. While in the test run we noticed is it a bit quieter than the one we had at our previous home. This on is liquid cooled which we were told it would be able to run longer without any problems. Our weather here we have had two instances where we were out of power for 10-12 hours. Looking forward to be ready for the winter!

The generator has been installed and no communication of when Centerpoint will in stall the gas meter

Our Generac Supercenter generator is the only one that our HOA will accept due to the fact that it is very quiet.

Love the peace of mind knowing this exceptional generator will be there to back up our entire house in the event of power failure.

How to clear 2760 code? Checked battery condition. It stays good.

The location of the Auxiliary Shutdown switch makes it very easy to accidently turn the generator off. A simple fix was to place a guard around the switch. Locating the power wires for the MLG Module was a nightmare. They were bundled with and behind another wiring harness next to the actual generator. They should be placed next to the battery box where they are to be connected. The recommended 5/8" mounting bolts will not fit through the holes in the frame. I had to use 1/2" bolts. I haven't had too actually use the generator yet. However, when the technician removed the utility power, the generator started and restored power in less than 10 seconds. We loaded it with two Heat pump units*, two electric water heaters, the oven, other appliances and normal lighting without any problem; and plenty of power to spare. * I did have the emergency supplemental electric heat strips in my large heat pump changed to propane because they consume a very large amount of power.

The machine seems well built and the installation was smooth but there is an important feature missing. I have a Kohler generator at another location and when it exercises weekly it also takes the full load at the transfer switch and then switches back to normal mode automatically before it runs its cool down cycle. This is a valuable feature as it really tests the whole system weekly, but the Generac cannot perform that and requires a manual override of the transfer switch so it cannot run an acutal full system test. Very disappointed!

Took forever to get it but once it arrived it was a smooth and professional install.

Our experience with Grasten has been a pleasure. With the supply chain what it is they delivered and commissioned the 38 KW well within their prediction on the timing and communicated with us very well along the way. This unit is much quieter than the 25 KW we had at our previous home and will easily carry our entire home, pool and all. We haven't needed it yet but feel comfortable that it will work great.

The General 27KW is a great product. Quiet and efficient. Walked through the setup and inspection to start for first time and was pleasantly surprised how capable the new generator is at handling 3500 sq.ft. of living space.

You can never get too big of a generator. More power is better..

My first impression is that the equipment looks good and the installer was excellent. The real test of course will be when the power fails due to weather disaster. I was very unhappy with the lack of communication from the back office regarding scheduling and status of equipment delivery.

A seamless transition to the generator when the power went out

With having two EV's in the garage, I needed larger than the typical generator. Plus I truly like the continuous optional option with a water cooled engine. All this said, I am truly pleased with both the unit and the installation.

I like that this unit comes on as necessary and powers the whole house wiithout me having to worry about what to shut off and what to run. Only problem is a small oil leak under the engine. Hopefully that can be fixed without too much hassle. Waiting for return call from installer.

we love this power back up solution. Problem was that the generator won't send status to my wifi. My wifi connects to the generator, but the generator fails to send it's status. Generac help on line is useless and provides no assistance at all. I paid for this capability, but there's no way to ensure it works and Generac fails to help.

I was pleased with the professionalism of the install team, as well as with the appearance of the genset and the accessory utility work that accompanied the install (gas, electricity, foundation). The job was completed satisfactorily in 1 day, and we are comforted to know that we are now "power secure" as we enter the peak of the hurricane season. The unit will fully cover our standby generator needs and expectations.

Took far too long. Feb to sept. Communications during this was totally lacking Once installation started the progress was very good. The crew showed me how to run it up and gave me the documentation for the Generac. They did not connect the WiFi connection. I will need to call in the morning. Overall, I am impressed with unit and look forward to using the WIFi

Hopefully we will never have to use the Generator but in testing and weekly runs the unit is very quiet compared to others. We have to place the unit 5 ft in air due to flood plane in Houston and the small footprint made this quite easy. Looks are very clean.

Can’t wait to see this big boy in action. I’m very please with it’s appearance as well as for now the Quietness of the Engine during startup. Very pleased

I needed a high quality reliable generator that I could depend on. Generac has been the leader in this field. I am a master electrician and have installed many back up power systems over the last 42 years. I believe Generac systems are the best and the the easiest system to install.

Well designed. All essential parts (battery, oil dipstick, on/off controls) easily accessible. Will be easy to maintain.

Great machine! Quality design and build! Engine protective interlocks seem adequate, but I wish that that the temperatures, pressures, and levels were viewable over the phone app. All positive comments for the device. This Generac replaced a 2006 Generac 40KW that had been damaged by a lightning surge. My negative comment is that it took 4.5 months to ship...I suppose COVID had something to do with that issue.

Great product that provides great piece of mind.shawn

This unit does everything it was advertised to do. Runs very quietly and provides enough power to meet all my electrical needs.

Power went down a couple of days after installation, generator came on and shut down when power came back on.

Make sure not to make location decisions and plans with the sales people, there were too many things I wanted that weren't possible due to regulations but the sales person said yes. While we like the product it is not as initially described.

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).
