Portable Generators
Portable generators are one of the most affordable backup power options.
Advantages include:
- Lower upfront cost
- Mobility
- Temporary emergency power
- Wide range of sizes
Portable generators can power essential items such as:
- Refrigerators
- Lights
- Small appliances
- Sump pumps
However, they require manual setup and fueling during outages.
Portable generators should never be operated indoors or in enclosed spaces due to carbon monoxide risks.
Standby Generators
Standby generators provide automatic backup power when utility service is interrupted.
Benefits include:
- Automatic operation
- Whole-home coverage
- Reliable performance
- Increased home value
- Long-term convenience
These systems are permanently installed and connected to an automatic transfer switch.
When utility power fails, the generator starts automatically and powers selected circuits or the entire home.
Many homeowners choose standby generators for maximum convenience and reliability.
Whole-Home Generator Systems
Whole-home generators are designed to power nearly every electrical system in the house.
They can support:
- HVAC systems
- Refrigerators
- Freezers
- Water heaters
- Lighting
- Home offices

These systems are ideal for homeowners who want uninterrupted comfort during extended outages.
Partial Backup Systems
Not every homeowner needs whole-home power.
Many families choose to power only critical loads, such as:
- Refrigeration
- Lighting
- Heating equipment

Partial backup systems often reduce installation costs while still providing essential protection.
Battery Backup Systems
Battery energy storage systems have become increasingly popular.
Advantages include:

Solar Battery Backup
Solar battery systems combine solar energy generation with battery storage.
Benefits include:

During normal conditions, excess solar production charges the battery system.
When an outage occurs, stored power can supply critical household loads.
Automatic Transfer Switches
A transfer switch is a critical component of many backup power systems.
Its purpose is to:

Professional installation is essential for safety and code compliance.
Choosing the Right Generator Size
