Deye SUN-SMART-TX01 – LoRa Smart Transmitter for Wireless Energy Management

The Deye SUN-SMART-TX01 is a compact LoRa-based Smart Transmitter designed specifically for Deye hybrid inverters. Its purpose is to transform the inverter into the local control center of a smart home IoT system, enabling intelligent, real-time management of energy consumption—all completely wirelessly, even without an internet connection. The device can be easily connected to the inverter’s Meter port and instantly paired with components of the Deye LoRa ecosystem.

What is LoRa and why is it better than Wi-Fi?

LoRa (Long Range) communication technology is one of the best solutions for home energy systems because it operates with extremely low latency. While Wi-Fi-based devices struggle with a 3–5 second response time—since data is routed through the cloud—the Deye LoRa solution responds with a mere 0.2-second response time. This is particularly important for the zero-export function, where the inverter must react immediately to changes in consumption to prevent energy from being fed back into the grid. Additionally, LoRa devices continuously communicate with each other even without an internet connection, ensuring system stability even during power outages or network failures.

The Smart Energy Management System

The SUN-SMART-TX01 transmitter forms the heart of the Deye Wireless Energy Management System. All components of the system—from the Wireless CT current transformer through the Smart Plug and Smart Switch units to the electric vehicle charger—communicate with the inverter via this device. The Wireless CT (SUN-SMART-CT01) is installed in the distribution panel and monitors energy consumption in real time via LoRa and RS485 communication, displaying voltage, current, power, and energy data on an LCD screen. The Smart Plug and Smart Switch devices turn loads on or off based on the battery’s state of charge (SOC) or the current scheduling settings—all controlled either via the Deye Cloud app or directly from the inverter’s display.

Technical Specifications and Compatibility

The SUN-SMART-TX01 transmitter operates on a 5V DC power supply, features a built-in antenna (0.56 dBi gain), and communicates within the 863–870 MHz frequency range at a range of up to 200 meters. It measures just 137.8 × 31.3 × 31.3 mm and weighs 45.8 grams. Once installed, it achieves an IP65 protection rating and operates from –40°C to +60°C. It is compatible with all Deye hybrid inverters, so it can be integrated into both new systems and existing installations with minimal configuration. It comes with a 2-year warranty and is certified to IEC/EN 62368-1.

Why choose the Deye Smart system?

The greatest value of the Deye Wireless Energy Management System lies in its combination of simplicity and reliability. No external control unit or complicated wiring is required—your existing Deye inverter becomes the core of the smart system. SOC-based and time-based control strategies ensure that consumers receive electricity exactly when it is cheapest or when the solar panels are generating sufficient energy. This results in significant long-term savings on electricity bills while maximizing the self-consumption of generated solar energy.

SOLARKIT Reviews

The Deye SUN-SMART-TX01 and its accompanying Wireless Energy Management System are one of the best and most comprehensive solutions for smart solar homes. The system’s greatest strength is LoRa communication: it’s lightning-fast, reliable, and works even without an internet connection. It’s compatible with all Deye hybrid inverters and can be expanded modularly with Smart Plug, Smart Switch, Wireless CT, and Smart EV Charger units. This system is recommended for those who want to take the efficiency of their solar system to the next level.
