The Jackery Smart Transfer Switch (automatic transfer switch) seamlessly switches between the main electricity system and the power backup solution to ensure continuous power supply to the appliances. It is designed to integrate with solar panels and rooftop PV systems via the Jackery Explorer 5000 Plus Portable Power Station for uninterrupted power supply to the appliances.
The Jackery Smart Home Kit comprises the Jackery Explorer 5000 Plus Portable Power Station and a Jackery Smart Transfer Switch. It supports 12 essential household circuits that accommodate a range of household appliances, such as TVs, refrigerators, network services, starklink, sump pumps, and lighting.
Whether you're dealing with an unexpected blackout caused by a storm or living completely off the grid, this reliable, high-capacity power solution like Jackery Smart Home Kit has you covered.
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 Explorer 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.
How to Install Smart Transfer Switch
Here's the step-by-step process in PDF file for you to down: install the Jackery Smart Transfer Switch.
Note:
1. If you have installed the Jackery Manual Transfer Switch, please uninstall it before installing the Jackery Smart Transfer Switch.
2. You should be a certified electrician to process the installation.
Step 1: Install the Wall Mount
The first step is to use a hand drill to install the upper and lower wall brackets on the back of the STS. Secure the template on the mounting wall and then carefully mark each hole location using a pencil.
Step 2: Drill Holes and Secure the STS to the Wall
Next, drill holes in the wall and then secure the Smart Transfer Switch. To do this, install the upper and lower wall brackets on the back of the STS using four M4 screws.
Note: During the drilling process, make sure to cover the interior equipment to prevent debris and dust from interfering with the equipment.
Step 3: Connect the Power Station
Start connecting the Jackery Explorer 5000 Plus Portable Power Stations with the STS (Smart Transfer Switch). Once the connection is established, make sure to lock the power input/output cable's plug.
Step 4: Connect the Mains and Load Circuits
Cover the front panel before using the Smart Transfer Switch and connect the mains power at 240V. Connect the grid's hot, neutral, and ground wires from the electrical panel to the STS. Now, connect the hot, ground, and neutral wires to the STS of the load circuit.
Step 5: Download the Jackery Mobile App
Download the Jackery mobile app on your Android or iOS device and then bind it to the newly installed backup power system. Press the IoT button to enable Bluetooth or WiFi and then add the device.
Step 6: Configure Split Phase in the App
Finally, two single-pole circuits are combined to create a two-pole 240V circuit. You can update the circuit names based on the connections made during installation. That's it! The installation of the Jackery Smart Transfer Switch is complete!
How to Remove Smart Transfer Switch
If you want to remove the Jackery Smart Transfer Switch, you need to follow some steps like turning off the breakers, disconnecting the power station, unlocking the panel, etc. Let's check the step-by-step removal process (click to download the PDF file) below:

Start by turning off the Jackery Explorer 5000 Plus Portable Power Station. Then, turn off the circuit breakers on the Smart Transfer Switch and the home distribution panel.
Step 2: Disconnect with Power Station & Unlock the Panel
Unlock the power input/output cable's plug from the Smart Transfer Switch to the Jackery Explorer 5000 Plus Portable Power Station. Lastly, unlock the STS cover.
Step 3: Disconnect the Grid Conductors
Start disconnecting the hot, ground, and neutral wires from the electrical panel to the Jackery Smart Transfer Switch.
Step 4: Disconnect the Home Load Conductors
Similarly, disconnect the load circuit's hot, ground, and neutral wire from the smart transfer switch.
Step 5: Remove Brackets
The final step is to remove the upper and lower wall brackets on the back of the Smart Transfer Switch.
