My Mother got a similar whole house generator for my Grandmother's house while she lived there, and also got one for hers. Living in the sticks, the power goes out a lot.

My Mom installed automatic whole house generators. These go on automatically when the power goes out. This was especially important for my Grandmother's house, as she could not go outside and do it all by herself.

The other important feature these units have is a surge protection. If you do not have a surge protection included in the installation the surge from the unit coming on may fry the house electrical system. This happened to my Mom's house before. Thus she made sure to have it installed properly.

Once installed properly they are fantastic things to have. No worries when the big bad storm comes.

Also, now that my Mom is selling my Grandmothers house this unit is an additional feature that helps the house being sold. My Mom is working on the closing of the sale now.

I hope my family's experience helps yours.
