Peace of Mind / Quality / Convenience

Living in the heartland, "...where the wind comes sweeping down the plain...", and the ever present possibility of bitter cold and ice storms in the winter, the threat of power outages is high. We experience a mean average of 5-7 outages a year. Those outages can last minutes to days, anecdotally, 2-4 hours in my experience. No more portable gensets, no more stored gasoline, no more extension cords and inlet boxes, no more breakers and interlocks. No more fighting the elements to get the power back on. Generac does all that automatically and in about 15-20 seconds. That friends, is peace of mind!

Great Home Standby Generator

Great home stand by generator. Did the installation myself. The installation instructions were very good. All electrical connections between the generator, utility power, and automatic transfer switch were detailed and precise. Startup and checkout was easy.
