## Summary description

EPEVER MT52. Product type: Energy meter, Product colour: Black. Width: 114 mm, Height: 114 mm, Weight: 230 g. Package weight: 320 g

## Long description

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

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.
