2.1 Features
The new-generation remote display unit MT50 for PUxxxxB(P), LSxxxxB(P),
VSxxxxBN and TracerxxxxBN(P) controllers is an associated display device
which supports both the latest communication protocol and the voltage
standard of solar charge controllers. The product has many useful functions:
■Automatic identification of the type, model and relevant parameter data of
various solar charge controllers
■Real-time display of the operational data and working status of the
connection devices in digital, graphical and textual forms by a large-screen
multifunctional LCD;
■Direct, convenient and rapid operation of six navigation function keys;
■Both data and power flowing on the same lead, no need for external power;
■Real-time data monitoring and remote load switchover of the controllers,
data browse and modification of device parameters, charge control
parameters and load control parameters;
■Real-time display and acoustic alarm of failure information of the
connected devices;
■Longer communication distance via RS485.
