What is a Smart Transfer Switch?
A Smart Transfer Switch (STS) is a power switching device that can automatically switch between the main electricity supply and backup power supply to ensure continuous power during outages.
When the electricity grid fails to supply electricity, the Smart Transfer Switch automatically switches to a backup source like a battery backup or a solar generator to supply uninterrupted power to the electrical appliances.
The Jackery Smart Transfer Switch can be paired with the Jackery Solar Generator 5000 Plus to ensure seamless (less than 20ms) power switching between the main and backup power supply, so you are never left without power.
How Does It Work and Target Scenarios
The STS (Smart Transfer Switch) carefully monitors the voltage and frequency of the main electricity supply. If the main power fails, such as when a low voltage or an outage occurs, the transfer switch immediately switches to the backup power supply. Once the power supply is restored, the Smart Transfer Switch automatically switches back to the main electricity supply and shuts the backup power system.
The Smart Transfer Switch is essential for users looking for a reliable power solution for their disaster backup power needs. Let's check out different scenarios where a transfer switch sounds like a reliable choice:
Emergency Backup Power Users
If you live in an area that experiences frequent power outages or unstable electricity, pairing the Jackery Solar Generator 5000 Plus with the Jackery Smart Transfer Switch offers a reliable emergency backup power solution. It provides a 20ms UPS switchover and lets you power essential circuits during power outages.
Off-Grid Cabin Power Users
The Smart Transfer Switch can connect to off-grid cabin circuits and solar panels, allowing you to completely use green energy. With the Jackery Smart Transfer Switch, you get the added value of intelligent power management. For example, the companion Jackery mobile app helps you check power usage in real-time and even optimize energy consumption.
If you are using the solar generator in the backup mode and the power is sufficient, the STS can supply power to non-essential circuits in the off-grid cabin. However, once the backup generator's power drops below a certain value, the system automatically stops powering non-essential appliances and switches to essential circuits like the refrigerator and lighting.
Daily Use (Peak Shaving and Valley Filling)
If you're someone who wants to reduce their electricity bills, you might benefit from the peak shaving and valley filling features of the Smart Transfer Switch. You can develop charging and discharging plans based on the electricity prices to save on bills. For example, if the electricity price drops in the morning, you can schedule the charging of the power station during those off-peak hours.
The Jackery Smart Transfer Switch also offers longer backup time by helping critical devices receive priority support so there is no unnecessary power consumption. When the power station has sufficient charging, it starts charging the non-essential circuits. However, when the power drops below a set value, it only charges essential appliances like refrigerators and lighting.

Comment: Hi, can you configure your Jackery Explorer 5000 to run the circuits in the STS to use solar power first and then Jackery battery power and finally switch back to grid if neccessary?
-Reply: Jackery 5000 Plus can run the circuit in the STS but can't switch the power back to the grid.
I’m interested in getting a Explorer 5000 Plus + Smart Transfer Switch.I currently have a Solar system installed that backfeeds to the grid.the solar systems stops working during an outage. Ideally it would be nice for the solar system to continue to to charge the Jackery system during an outage, How will the Smart Switch work with this, or is it possible?
To Jim Hinton:
I don’t have a grid-tied solar system so I can’t give you a definitive answer, just a suggestion. The 5000+ can input up to 4000 watts of solar. You could, theoretically, disconnect some of your existing panels from the grid-tied inverter and instead route them directly to the 5000+. That would split your existing solar into two different arrays, a “grid tied” and an “off grid” solar array. They could work simultaneously, the off-grid array would power the 5000+ and the grid-tied array would power your main panel. If the load on the circuits in the STS are 4000 watts or above, you’d get 100% of the production of your 10K system just like you do now. If the load your main panel is less than 6K (excluding the STS’s loads) then your grid-tied system will still be able to sell the excess solar production back to the grid, but only up to 6K worth. I don’t know how much your system generates and exports, but if it’s never more than 6K, then it seems to me that this dual system gives you the best of all worlds: 10K of usable solar, export to the grid, and 4K of usable solar when the grid’s down.
To Terry: No. The STS only works with the 5000+.
(not a Jackery official, just an STS owner)
To George Swanner: Sort of. But not exactly. Solar only goes to charging the battery, that’s all it can do. So if the battery discharges to meet the load, then the solar can charge it right back up. The net effect is that basically it is using solar to meet the load, but it has to be run through the battery first.
Second, using battery first and grid as a last resort: yes you can do this. You can tell the 5000+ not to recharge itself from the grid, so it’ll recharge itself from solar as long as the sun’s out, and then it will run the circuits in your STS for as long as the battery lasts. You can even assign priority to the circuits so that some of them are “essential” and some are “would be nice to have”. If the battery’s fairly charged up, it’ll run all those circuits, but if the battery depletes to a pre-set level then the STS will disable the “nice to have” circuits so that the remaining power can be focused on the “essential” circuits.
If the battery of the 5000+ is completely depleted and there’s no solar coming in, and you’ve told it not to recharge itself from the grid, then the STS will switch back to full grid mode.
You can also tell the 5000+ not to recharge itself during certain hours, so if you have on-peak and off-peak pricing from your power co, you can tell it to wait for off-peak times before recharging itself.
Hello, can the smart transfer switch panel feed into an existing Manual switch panel (that is already installed with the house electrical panel)?
