Rated 5 out of 5 by from 27KW GENERATOR I PURCHASED SAME SIZE GEN SET FROM EATON IN 2014 WHICH OPERATED FLAWLESSLY UNTIL LIGHTNING HIT IN JULY 2022. I SEARCHED HIGH AND LOW FOR SAME UNIT AND FOUND IT IN NEW ORLEANS. I PICKED IT UP AND RETURNED TO MY HOME WHERE SEAL ELECTRIC (GENERAC DIST.) DID THE REPLACEMENT. INSTALLATION AND START UP. NOW WORKING GREAT! I DO NEED A "KEY" TO OPEN THE DOORS AS THERE WAS NOT ONE WITH THE UNIT WHEN PICKED UP. PLEASE SEND ONE. THANK YOU!

Rated 5 out of 5 by from Quality product Only thing I don’t like is the display shows hours protected. Don’t care. Need to know hours run time for maintenance purposes. Should not have to scroll through menu every time to find it.

Rated 4 out of 5 by from We are officially ready for Hurricane Season Knowing we now have a full house generator is powerful itself. Do we wish it wasn’t as pricey, didn’t take an additional 3 months from when we were told it would be delivered, and came with a start up kit (oil, filter, spark plugs, etc) needed as a back up. I have been struggling to find such a kit and both Generac and their main distributor haven’t been helpful at all to assist with such needs. Let’s hope the product is as great as those say it is when it gets out to the true test of Mother Nature.
