MT52 LCD Solar Controller Remote Display – RS485 Monitor Unit
MT52 LCD Solar Controller Remote Display – RS485 Monitor Unit
MT52 LCD Header Unit – Solar Controller Remote Display & Communication Device
The MT52 LCD Display Unit is a next-generation remote monitoring and communication device designed for EPEVER solar charge controllers. Using a long-distance RS485 communication bus and an RJ45 interface, it connects directly to your controller and delivers real-time operational data, adjustable charging parameters, and full load control — all from a clear, large multi-function LCD screen. Made in Mainland China.
Key Features
- Automatic Device Identification: Instantly detects and displays the type, model, and key parameters of the connected controller.
- Multi-Function LCD Display: Large, high-clarity screen showing real-time numbers, graphics, and text — including charging status, voltage, current, and working mode.
- 6 Navigation Buttons: Intuitive front-panel controls for fast, easy browsing and parameter adjustment without a computer.
- Real-Time Data Monitoring: Continuously tracks operational data and working status of the connected controller.
- Adjustable Charging Settings: Browse and modify charging/discharging control parameters, equipment parameters, and load control settings on the fly.
- Multiple Load Working Modes: Set load mode directly from the header — choose from Manual, Pure Light Control, Light Control + Delay, or Timing.
- Remote Load Switch: Remotely toggle the controller's load output without accessing the controller itself.
- Voice Fault Alarm: Built-in audio alarm triggers and displays fault information whenever an issue is detected on the connected equipment.
- RS485 Long-Distance Communication: RS485 bus architecture allows extended cable runs between the display and the controller.
- Factory Reset: Restore all default parameters with a simple button sequence.

Frequently Asked Questions
Q: Which solar charge controllers is the MT52 LCD display unit compatible with?
A: The MT52 LCD header unit is designed for compatibility with EPEVER solar charge controllers that support the latest RS485 communication protocol. It automatically identifies the connected controller's type, model, and parameters upon connection.
Q: How far can the MT52 be installed from the controller?
A: The MT52 uses an RS485 communication bus via RJ45 connector, which supports long-distance communication well beyond the included 2 m standard cable. Extended RS485 cables can be used to mount the display panel at a convenient monitoring location away from the controller.
Q: Does the MT52 require an external power supply?
A: No separate power supply is required. The MT52 draws power directly through the RS485/RJ45 communication cable connected to the controller, with a self-consumption of less than 15 mA when the LCD backlight is active.
Q: Can I adjust charging parameters directly from the MT52 display?
A: Yes. Using the six front-panel navigation buttons, you can browse and modify charging control parameters, load control settings, and equipment parameters in real time — without needing a laptop or additional software.
