What Size System Do I Need? |
| Guardian emergency power systems are available in a variety of output sizes ranging from 6-40 kW. The size that will work best for you will depend on the wattage requirements for your home or business. Once we determine the output you need from your generator and the type of fuel you wish to use, we can specify the emergency power system that is right for you. A 20% safety factor is recommended to support your electrical appliances with induction motors, which require 2 to 3 times the listed wattage in order to start. Additional capacity may also allow you to add more circuits in the future. |
| To ensure safe and proper installation and adherence to all local building code specifications, we will assist you in choosing the Generac Power System that is correct for your application and will then install the system with factory certified installers or other licensed professional. |
| Below are some broad guidelines that show the power consumption of some of the items you may wish to attach to your Generac Power System. For final determination of size, have one of our professionals evaluate your requirements and determine the exact equipment you require. |
