im a generac trained service tech, however i dont work on liquid cooled units, only air cooled. (in the past i have done some basic service on some 24-48KW units, and find that they have very few issues. ). weird that a new unit isnt operational. i take it the guy that installed it probably isnt a liquid cooled service tech. you dont need to be one to buy and install the unit. your neighbor needs to get ahold of an industrial certified generac tech. they can be found on generac website. this should be 100% covered under warranty as long as unit was installed correctly. i have seen these large units installed wrong in the past. usually with too small of a fuel supply. I service 100's of air cooled units every year, and really have very few issues. during the last power outage in my area, some of my customers were under generator power for 36 straight hours. i only received 4 calls during outage, 3 were from people i never worked for before and one from a customer. on my customers unit somehow the generator breaker was shut off....few seconds later while on phone he had power again thru generator. the other 3 i was able to talk thru getting online over the phone. i really have no issues with generac as a product. but like anything there can be a lemon. Due to covid workplace restrictions, generac is over 82,000 units backordered as of a week ago. parts are also starting to be an issue. but so is everything else. go to home depot and look at electrical breakers....shelves here are empty.
