I am widowed - need a reliable, easy to use alternate system for emergeny power. Have 100 gal propane tank, is this large enough. Does unit set outside? Is installation difficult/
Marie Dye

Answer
These units are a great choice for a back-up power system as they start automatically without any assistance from you.

A 100 Gallon tank will not provide sufficient back-up fuel supply for emergency situations and recommend either its own tank or a larger 200 Gallon tank.

Installation is not too difficult on these units as the essential circuit models are prewired for ease of installation.

Please keep in mind that a certified electrician or local Generac technician should install any home standby system as they will be familiar with all of your local city, county and state codes.
