Imagine a storm knocks out your power in the middle of the night. The refrigerator stops cooling, the heating system shuts down, and your family is left in the dark. A standby generator solves this problem by automatically restoring power within seconds. This guide covers the best standby generators for residential use in 2026, focusing on models from Generac, Kohler, and Jackery. Whether you need whole-home backup or a portable solar solution, we have you covered. For more insights, check out our best standby generator for home guide.

Buying Guide

Power Output and Capacity

The first factor to consider is how much power you need. Standby generators range from 10 kW to 22 kW for whole-home models, while solar generators like the Jackery offer expandable capacity up to 60 kWh. Assess your home’s critical loads, such as refrigeration, heating, and lighting, to choose the right size. A larger generator provides more coverage but also requires more fuel and space.

Fuel Type and Efficiency

Generators run on natural gas, liquid propane, or solar power. Natural gas models, like those from Generac, offer lower fuel costs and automatic operation. Solar generators, such as the Jackery and BLUETTI, provide silent, emission-free backup but may need sunlight for recharging. For dual-fuel options, see our best dual fuel generators gas and propane guide.

Automatic Transfer Switch

An automatic transfer switch (ATS) is essential for standby generators. It detects a power outage and starts the generator within seconds, then switches back to utility power when it returns. Many Generac and Kohler models include a built-in ATS, simplifying installation and ensuring seamless operation.

Remote Monitoring and Control

Modern standby generators offer cellular connectivity for remote monitoring. With the Mobile Link app, you can check generator status, receive maintenance alerts, and control the unit from anywhere. This feature is especially useful for vacation homes or frequent travelers. For more on whole-house solutions, read our top whole house generators article.

Final Thoughts

Choosing the right standby generator depends on your home’s size, budget, and power needs. For most households, the Generac 14kW Whole Home Generator offers an excellent balance of power, reliability, and remote monitoring. If you prefer a sustainable, quiet solution, the Jackery HomePower 3600 Pro Max and 2x200W, 3584Wh provides expandable solar backup with seamless UPS switching. Both models ensure your home stays powered during any outage.
