Standby Generators comparisons.
Portable Generator vs. Whole-House Standby Generator
Backup power generally comes from a portable generator you set up manually during an outage, or a whole-house standby system permanently installed and wired to start automatically.
Natural Gas vs. Propane Standby Generators
Whole-house standby generators typically run on either natural gas from an existing utility line or propane from an on-site tank, and the right choice often comes down to what's actually available at your home.
Before you hire or buy.
- How much of our home's power load do we actually need to cover?
- What fuel source is realistically available at our home?
- How often and how long do outages typically last in our area?
Standby Generators questions, answered.
Do standby generators require a permit to install?
Often yes — many jurisdictions require a permit and inspection for permanently installed standby generators, particularly given the fuel line and electrical connections involved.
