EPEVER MT52 solar panel accessory Energy meter

The EPEVER MT52 solar panel accessory Energy meter is a compact remote meter designed for use with solar charge controllers that support RS485 communication. Housed in a black 114 x 114 mm enclosure and weighing approximately 230 g, the MT52 provides a local interface for real-time monitoring, parameter reading and basic programming of compatible controllers. The meter draws power directly from the controller and connects via an RJ45 communication port to deliver status updates and alarms on a clear local display.

Advantages

The MT52 offers simple installation and operation with direct power supply from the controller, eliminating the need for a separate power source. It shows real-time fault alarms and system status, enabling quick identification of issues. Local parameter reading and basic programming through the meter reduce the need to access the controller physically. Its compact size and RJ45 communication interface make it suitable for retrofit installations and tidy mounting near the controller.

Suitable for

• Monitoring small to medium off-grid solar systems with RS485-compatible controllers
• Local parameter checking and configuration of solar charge controllers
• Remote meter installation where a compact, wall-mountable display is required
• Maintenance tasks that require quick access to real-time alarms and status

How to use

Mount the MT52 near the solar charge controller in a dry, accessible location and connect the RJ45 communication cable to the controller's RS485 port following the manufacturer's wiring diagram. The meter receives power from the controller once connected and will display system status and parameters automatically. Use the meter's controls to scroll through readings, view stored parameters and acknowledge or inspect fault alarms. Refer to the controller and meter manuals for details on navigation and parameter programming via the MT52.

Usage recommendations

Install the MT52 in a location protected from direct weather exposure and extreme temperatures. Ensure secure RJ45 connections and correct RS485 wiring to avoid communication errors. For reliable readings and alarm handling, keep firmware of both controller and meter up to date and consult technical documentation when making parameter changes.
