Which emergency generator is suitable for home power?

A suitable backup electricity generator for home power depends on the size of the house and the electrical needs in the event of an outage. For whole-home coverage, backup generators from brands like Generac, Kohler, and Cummins are often recommended.

These generators are permanently installed and automatically activate during a power outage, providing continuous power to your home. Standby generators typically offer power ratings ranging from 10 kW to 20 kW or more, making them ideal for powering an entire home, including essential appliances and systems.

For smaller or partial home power, portable generators from brands like Honda or Champion, with outputs ranging from 3 kW to 10 kW, may be suitable, although they require manual setup.

Which generator to power a single-family home?

You should not inject power from a backup generator directly into the home grid without appropriate safety measures.

Doing so without a transfer switch can cause backfire, where electricity flows back into the power lines, posing a serious risk to utility workers and potentially damaging your generator. Instead, a transfer switch should be installed to safely disconnect your home from the grid during an outage and direct power from the generator to selected circuits in your home.

This ensures that power is distributed safely and prevents dangerous power feedback.

What is the difference between an inverter generator and an AVR?

The amount of kilowatts (kW) a backup generator needs for a home depends on the total electrical load you want to support during an outage. For a small home or one powering only essential systems, a generator with a capacity of 5 kW to 7 kW may be sufficient.

For larger homes or those requiring more extensive coverage, including multiple appliances and HVAC systems, a generator with a capacity of 10 kW to 20 kW or more may be necessary.

To determine the exact size, calculate the wattage of the appliances and systems you intend to power and choose a generator that can handle that load with extra capacity to avoid overloads.

For a single-family home, the type of backup generator you need depends on the demand for electricity and whether you want full or partial backup of the home.

A backup generator is ideal for whole-home backup, providing automatic power without manual intervention. These generators are typically powered by natural gas or propane and have capacities of 10 kW to 20 kW, making them suitable for most single-family homes. If you only need to power essential appliances, a portable generator may be sufficient.

These generators, with capacities between 3 kW and 10 kW, can power selected circuits via a transfer switch but require manual setup and fueling.

To connect a backup generator to your home, you must install a transfer switch connected to your home’s electrical panel. The transfer switch allows you to safely disconnect your home from the grid and route generator power to your selected circuits. In the event of a power outage, you switch power to the generator by activating the transfer switch, which ensures that only the circuits connected to the switch receive power.

This prevents feedback and ensures safe operation.

Transfer switch installation must be performed by a licensed electrician to comply with local codes and ensure safety.
