MT52 LCD Solar Controller Monitor – RS485 Remote Display Unit
MT52 LCD Solar Controller Monitor – RS485 Remote Display Unit
MT52 LCD Header Unit – Real-Time Solar Controller Monitor with RS485 Communication
The MT52 LCD Display Unit is a next-generation remote monitoring accessory designed for EPEVER solar charge controllers. Connecting via RS485 (RJ45 interface), it delivers real-time visibility into your solar system's operating data, letting you browse and adjust charging parameters, configure load control modes, and receive instant voice fault alerts — all from a clear, multi-function LCD screen.
Whether you're managing an off-grid solar setup, a battery bank system, or a remote installation, the MT52 puts full controller oversight at your fingertips without the need for a PC or wireless connection. Made in Mainland China.
Key Features
- Automatic Device Identification – Instantly recognizes the type, model, and parameters of the connected EPEVER controller.
- Multi-Function LCD Display – Large, clear screen shows real-time operational data in numbers, graphics, and text format.
- 6 Navigation Buttons – Intuitive, fast interface for browsing and modifying all controller settings on the spot.
- Adjustable Charging & Load Parameters – Remotely browse and modify charging control settings and load control parameters directly from the unit.
- Multiple Load Working Modes – Set load mode to manual, pure light control, light control + delay, or timer via the header unit.
- Voice Fault Alarm – Audible alert triggers when fault conditions are detected on the connected controller.
- Long-Distance RS485 Communication – RS485 bus interface supports extended communication distances, ideal for larger or distributed installations.
- Low Self-Consumption – Draws less than 15 mA with LCD backlight and sound alarm active, keeping your system efficient.
- Wide Operating Temperature – Rated for environments from -20°C to +70°C (-4°F to 158°F).

Frequently Asked Questions
Q: What solar 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 use the RS485 communication protocol. It automatically identifies the connected controller's type, model, and operating parameters upon connection.
Q: Does the MT52 require a separate power source or batteries?
A: No — the MT52 draws its operating power directly from the connected controller via the RS485 data cable. No external power supply or batteries are required.
Q: How far can the MT52 communicate with a solar controller?
A: The RS485 bus used by the MT52 supports long-distance communication, significantly exceeding the range of standard serial connections. The included cable is 2 m, but the RS485 interface can support extended cable runs in larger installations.
Q: Can I change the load working mode using the MT52 display unit?
A: Yes. Using the six navigation buttons on the MT52, you can set the connected controller's load operating mode to manual, pure light control, light control + delay, or timer mode — all without needing a PC or additional software.
