Overview
The Epever MT11 remote meter (remote meter monitor) is an accessory compatible with the DuoRacer series charge controller (DRN series). It monitors running data and working status, browses controller parameters, allows setting battery type and temperature unit, and can clear generated energy data. It is suitable for RV, camper, boat, and similar applications.
Key Features
- Automatically identifies and displays the type, model, and relevant parameter data of controllers.
- Real-time display of operational data and working status (digital, graphic, and text) on a large-screen multifunction LCD.
- Three touch buttons for quick operation (two function buttons and one switch button).
- No external power supply required; the charge controller powers the MT11.
- Browse controller parameters; set battery type and temperature unit; clear generated energy data.
- Real-time display of failure information of connected devices.
- Longer communication distance based on RS485.
