What Size Generator Do I Need?

So you've decided you want the peace-of-mind that only backup generator power can provide. Right off the bat, the biggest hurdle is how to size your generator.

There are two types of generators:

• Portable generators require manual setup but can be taken anywhere for on-the-go power. They are best for powering critical appliances and typically max out at 17,000 watts.
  
  
• Standby Generators are permanently installed and hardwired to your home. They can power everything from essential circuits to the whole house and automatically monitor for power outages, at which point they turn themselves on/off.
