Your Inverter’s Smart Features – Are You Using Them Right?

Master the setup and operation of the Smart Devices module for your inverter with this all-in-one technical guide. Covering Smart CT, Smart Switch/Plug, Smart EV Charge and Smart TX, this post breaks down every function, setup step and key parameter for seamless energy management.

How to Access the Smart Devices Page

1. Locate the System Setuppage on your inverter panel
2. Click the Smart Devicesitem in the upper right corner to enter the main page
3. The main page features 4 core function options: Smart CT, Smart Switch, Smart EV Charge, Smart TX
4. For the detail page: Press the UP/DOWN buttons on the inverter panel when on the inverter details page—you can view real-time status of all connected smart devices here (and control manual-mode Smart Switches via on-page ON/OFF buttons)

Core Function Setup & Operation

1. Smart CT (Max 2 supported)

• Access: Click Smart CT in the upper left corner of the Smart Devices main page
• Setup: Enable the device via the upper left CheckBox → input the SN (found on the Deye smart CTnameplate)
• Function: Real-time energy monitoring integration with the inverter system

2. Smart Switch/Plug (Max 10 supported)

• Access: Click Smart Switch in the upper right corner of the Smart Devices main page
• Basic Setup:
  1. Use UP/DOWN buttons to select the device → enable it via the upper left CheckBox
  2. Enter SN input page (click the upper left/right textbox on Smart Devices page)
  3. Tap Edit SN→ OK → input the device’s label SN via on-screen soft keyboard → OK to save
  4. (Optional) Tap Edit name→ OK → customize a device name → OK to save
• Control Modes (CANNOT be enabled simultaneously): Time Mode(Zone 1 programmable parameters; synced with cloud APP/website)

• Divide 24h into 4 time periods (only the 4th can cross midnight) → independent ON/OFF control for each period
• Key parameters:
  • Start-T/End-T: Time window for each period
  • ON-SOC: Auto-on when battery SOC reaches the set value (ON button active only)
  • OFF-SOC: Auto-off when battery SOC drops to the set value (ON button active only)
  • ON/OFF button: OFF = permanent off in the period; ON = SOC-based auto control
  • Week: Select specific weekdays for the schedule to take effect  Manual Mode(Zone 2 on-screen button + physical device button + cloud APP/website button)
• Direct one-click ON/OFF control for the device
  • Useful Setting: Off grid-sw off → Auto-off all connected Smart Switches/Plugs when the inverter switches to off-grid mode (enable via CheckBox)

3. Smart EV Charge

• Access: Click Smart EV Charge in the lower left corner of the Smart Devices main page
• Basic Setup: Enable via upper left CheckBox → input the EV charger’s label SN (follow the same SN input steps as Smart Switch/Plug)
• Working Modes:

1. Plug and Play: Operates as a regular load; no programmable schedule required
2. Time of Charge: 24h divided into 4 time periods (4th can cross midnight) → independent charging control for each period
3. Solar Energy Only: Charges only with excess solar energy (battery SOC ≥99%); auto-shuts when SOC ≤95% (6A minimum charging current limit at all times)
4. Free Work: Uses inverter AC output (solar + battery discharge) + bypass circuit AC input for charging
   • Off-Grid Protection Settings:

• Solar Energy Only (SOC>95%): Auto-off when inverter switches to off-grid mode
• Off grid EV Charge off: Auto-off when off-grid + battery SOC ≤ set Off grid SOC value
• Off grid SOC: EV charger remains on in off-grid mode if battery SOC > this set value
  • Other Key Settings:
• Connection ports: Grid port / Gen port (LD port) of the hybrid inverter
• Max charge power: Customizable upper limit for Plug and Play/Time of Charge modes

4. Smart TX

• Access: Click Smart TX in the lower right corner of the Smart Devices main page
• Key Operations:

• Communication Channel Adjust: Tap Zone 1 → use inverter panel UP/DOWN buttons to set the desired frequency (synced with cloud APP/website)
• Reset Smart TX: Reserved function (invalid in current firmware version; enable via CheckBox to trigger)
  • Critical Reminder: After adjusting the Smart TX communication channel, all connected Smart Switches/Plugs must perform channel re-scanning

 Universal Key Reminders

1. All SNs must be input as printed on the device label/nameplate
2. All programmable parameters are synced across the inverter panel, cloud platform APP and website
3. Time Mode and Manual Mode for Smart Switch/Plug are mutually exclusive
4. Smart TX channel adjustment requires re-scanning for connected devices
5. Solar Energy Only mode for EV Charge has a strict SOC trigger (99% on / 95% off) with a 6A minimum current limit

Save this guide for quick reference! All operations follow the same logic across the inverter panel and cloud platform for consistent, convenient control.
