Dynamic Load Balancing (DLB): Intelligent Power Management
DLB is an intelligent power management technology that monitors your home circuit current in real time and automatically adjusts the charger's output power — ensuring the total circuit current never exceeds its safe limit, preventing tripped breakers, equipment damage, and safety hazards caused by overloading.
- Total Current (user-set): Define your home circuit's maximum safe current per phase (adjustable 8A–99A). Any draw above this threshold would trip the breaker — DLB prevents this automatically.
- Charging Current: The real-time output current the wallbox delivers to the vehicle — continuously adjusted by DLB based on available headroom.
- Home Appliance Load: The total current drawn by all other appliances in the circuit, monitored live via the energy meter.
- Standby Current: The remaining safety margin = Total Current − Home Appliance Load − Charging Current — always kept positive to prevent overload.
DLB Setup via On-Unit LCD Menu
Configuring Dynamic Load Balancing is straightforward using the built-in LCD menu and touch buttons — no app or specialist required. Navigate to the DLB settings menu, enter your home circuit's maximum current, and the system handles everything else automatically from that point on.
- Step-by-step menu navigation using the four touch buttons: Back, Up, Down, and Enter.
- Set the maximum total current for your home circuit directly from the unit — no laptop or installer tool needed.
- DLB settings are stored in non-volatile memory — retained after power cycles without needing to be re-entered.
- Real-time DLB status visible on the LCD display during every charging session — confirm the system is active at a glance.
- Can also be configured and adjusted remotely via the Tuya Smart app over Wi-Fi.
2.8-Inch LCD Display: Clear Data, Full Control Without the App
The large 2.8-inch LCD screen gives you complete charging data and direct control over all key settings — current, delay timer, DLB parameters, and more — without needing your phone or a network connection.
- Displays charging current (A), charging voltage (V), and internal temperature live during every session.
- Four tactile touch buttons (Back / Up / Down / Enter) navigate the full on-unit menu system intuitively.
- Adjustable output current: 8A / 10A / 13A / 16A / 20A / 25A / 32A / 40A / 50A — covers the full range from standard household sockets to dedicated high-power circuits.
- Delay timer: schedule a delayed charge start directly from the panel — no app required.
- Readable in all lighting conditions; clear contrast keeps key data visible at a glance.
DLB Signal Cable Wiring & Button Layout
The DLB energy meter connects to the wallbox via a dedicated signal cable, enabling real-time current monitoring of the entire home circuit. The four-button panel provides direct hardware control at all times, independent of any app or network.
- Signal cable connects the external energy meter (CT clamp) to the wallbox — enables live whole-circuit current monitoring for DLB operation.
- Meter installs on the incoming supply, upstream of all home circuits, to accurately measure total household load.
- Return (Back): Exit the current menu level or cancel an input without saving.
- Up / Down: Scroll through menu options or increment / decrement a numerical value.
- Enter: Confirm a selection or save a setting — activates the highlighted action.
- All button functions are hardware-level — always operational regardless of Wi-Fi or app status.
RFID Card Management: Add, Delete & Toggle Access Control
The built-in RFID function lets you restrict charger access to authorised cards only — preventing unauthorised use when the charger is installed in a shared or accessible location. Card management is handled directly through the on-unit menu.
- Add a new RFID card via the menu: navigate to Card Management → Add Card → tap the card to the reader — registered in seconds.
- Delete individual cards or all cards at once from the menu — immediately revokes that card's access.
- Toggle the RFID function on or off in Settings: when disabled, the charger operates in plug-and-play mode without requiring a card swipe.
- 3 blank RFID cards are included in the box — ready to register immediately out of the packaging.
- Ideal for shared driveways, workplace installations, or any scenario where charger access needs to be controlled.
Two-Stage Thermal Protection: Auto Cut-Off at 85°C, Auto-Resume at 65°C
Rather than a hard shutdown with no recovery, this wallbox uses a two-threshold thermal protection system that cuts charging output when temperatures become unsafe and automatically restores it once the unit has cooled — minimising unnecessary charging interruptions.
- Cut-Off Threshold — 85°C
- When internal temperature reaches 85°C, the charger suspends all output immediately to prevent hardware damage and eliminate any fire risk.
- Auto-Resume Threshold — 65°C
- Once internal temperature drops back to 65°C, charging restores automatically — no user action required to restart the session.
- Operating Range
- Designed and tested for reliable operation from −30°C in freezing winters to +55°C in peak summer ambient temperatures.
Smart Schedule Charging: Off-Peak Automation via Tuya App
The Tuya Smart app allows you to set fully automated weekly charging schedules, ensuring your EV always charges during the cheapest electricity tariff windows — without any manual intervention each day.
- Set start and end times for every day of the week — the charger begins and stops automatically within the programmed off-peak window.
- Live peak/off-peak electricity cost graph in the app helps you identify the cheapest charging window for your tariff.
- Weekly recurring schedule runs automatically — set it once and the app handles the rest every night.
- Push notifications confirm when charging starts, stops, and when the vehicle is fully charged.
- Available free on Apple App Store and Google Play — search Tuya Smart.
RFID Access Control & Bluetooth / Hotspot Remote Control
Two additional layers of smart control give you both security and flexibility — physical RFID card access prevents unauthorised charging, while Bluetooth and hotspot connectivity keep the app working even without a home Wi-Fi network.
- RFID card swipe: when enabled, charging only starts after a registered card is presented — protects against unauthorised use in shared or exposed installations.
- Bluetooth control: connect directly to the charger within 10 metres via the app when no Wi-Fi network is available — ideal for garages without wireless coverage.
- Hotspot control: use your phone's mobile data hotspot to access full remote control anywhere with mobile coverage, without needing a fixed Wi-Fi connection.
- All three connection methods (Wi-Fi, Bluetooth, hotspot) are supported simultaneously — the app switches automatically to the available connection.
Four Charging Modes & Easy Device Management
The wallbox supports four distinct operating modes to suit every scenario — from fully automated app-controlled charging to simple plug-and-play for guests — and device binding/unbinding is quick and straightforward when changing phones.
