No power, no problem
4 days ago
Purchased the Generac 26K with transfer switch in September 2026 and system is easy to operate and maintain. System is monitored by my service provider and system advises them if there is a problem with system. My Generac runs our house completely if power goes out. We opted for a in ground LP tank which is super nice and keeps yard looking good.
Yes, I recommend this product.

Purchased the generator two years ago and have no issues. Haven’t had to use it often but it is a great comfort knowing that we are protected considering the storms that pop up increasingly
