1. Overview
The MT series remote meter is an accessory which is compatible with the DuoRacer series controller. It can monitor the running data and working status of the controller via the remote meter. The remote meter can browse the controller's parameters, set the battery type and temperature unit, and clean the generated energy. It is suitable for RV, Camper, Boat, and so on. Features Automatically identify and display the type, model and relevant parameter data of
controllers. Real-time display the operational data and working status of the connected
devices in digital, graphics and textual forms by a large-screen multifunction LCD. Three touch buttons are easy and quick to operate. No need for external power supply. Charge controller supplies the power for
MT11. It can browse the controller's parameters, set the battery type and temperature
unit, and clean the generated energy. Real-time display of failure information of the connected devices. Longer communication distance based on RS485.
