Its a large cost up front.. each generator was around $12k I believe. But I plan on staying at this home for a long time so I am sure it will pay itself back storm after storm.
Yeah it feels good to have options when the power goes out. About a month or so ago the power did go out and we ran on the generators for around 8 hours without much issue. Just need to adjust the hertz so the inverter did not trip. All and all it worked well.
