Our Top Picks

Before comparing, understand what you are buying. An automatic transfer switch (ATS) senses loss of utility power and moves your circuits to a backup source, then reverses when grid power returns. Transfer switches are rated by amperage, and that rating must match or exceed the service feeding the circuits you connect. Many ATS listings are sold as generator-ready, and some EcoFlow and Jackery owners use them with a station’s dedicated input or a generator. Confirm compatibility with your specific model before buying.

Buying Guide

Amperage Rating

Match the transfer switch rating to your main breaker or service. A 30 amp unit fits a small subset of circuits, while a 200 amp unit is meant for full service. Check your panel label before buying.

Good picks for this: RXSW200A3 200 Amp Automatic Transfer Switch, Nature’s Generator 30 Amp Manual Transfer Switch

Automatic vs. Manual Operation

Automatic switches detect outages and transfer on their own, which matters if you are away or asleep. Manual switches require a person to flip the unit, which is simpler and often less expensive to install.

Good picks for this: Jackery Smart Transfer Switch, 63A 110V Automatic/Manual Transfer Switch

Voltage and Frequency Support

Confirm the unit supports 120V or 240V service and 50/60Hz as needed. Most US homes use 120/240V split-phase at 60Hz.

Good picks for this: 100Amp AC110V Automatic/Manual Transfer Switch, AC120V 15Amp Automatic Transfer Switch

Enclosure and Location

Indoor garages and utility rooms can use a standard enclosure, while outdoor installs need NEMA 3R or similar weather protection.

Good picks for this: RXSW200A3 200 Amp Automatic Transfer Switch, Nature’s Generator 30 Amp Manual Transfer Switch

Compatibility with Your Backup Source

Check whether the switch is designed for a portable power station, a solar input or a standby generator. Pairing a switch with the wrong source can create backfeed hazards.

Good picks for this: Jackery Smart Transfer Switch, 63A 110V Automatic/Manual Transfer Switch

Use Case and Load Planning

List the circuits you want to keep running and add their wattages. Refrigerators, sump pumps and medical devices should be prioritized. The U.S. Department of Energy offers guidance on sizing backup power for essential loads.

Good picks for this: AC120V 15Amp Automatic Transfer Switch, 63A 110V Automatic/Manual Transfer Switch

Installation and Code Compliance

Transfer switches generally need a licensed electrician and a permit in most jurisdictions. Improper wiring can create backfeed to the utility grid, which is dangerous to line workers.

FAQ

What is an automatic transfer switch used for?

An automatic transfer switch moves selected circuits from the utility grid to a backup power source when an outage occurs, and returns them to the grid when power is restored.

Can I use an EcoFlow power station with a transfer switch?

Many owners connect an EcoFlow station to a transfer switch or inlet, but compatibility depends on the model and the switch. Check the manufacturer’s manual and consult a licensed electrician before wiring.

How do I know what amp rating I need?

Look at your main breaker size and the circuits you plan to back up. The transfer switch rating should match or exceed the load you intend to power.

Is a manual transfer switch safer than an automatic one?

Both can be installed safely when wired correctly. Manual switches require user action, while automatic ones depend on sensing equipment. Neither should be wired without following local code.

Do I need a permit to install a transfer switch?

Many areas require a permit and inspection. Requirements vary by jurisdiction, so check with your local building department.

Can a transfer switch power my whole house?

Only if the switch is rated for your service size and your backup source can supply the full load. Most homes back up essential circuits rather than everything.

Conclusion

For a complete Jackery-based system with automatic switchover, the Jackery Smart Transfer Switch is a logical starting point. Homeowners backing up a whole house with a generator should look at the 200 amp RXSW200A3. RV owners and workshops may prefer the 100 amp unit, while small kitchens and light loads suit the 63A or 15A options. Anyone preferring manual control will find the Nature’s Generator kit practical. Always have a licensed electrician verify the installation.
