General Information

Features

The new-generation remote display unit MT50 for LSxxxxB(P), VSxxxxBN and TracerxxxxBN(P) controllers is an associated display device which supports both the latest communication protocol and the voltage technology standard of solar controllers. The products have many excellent functions:

• Automatic identify and display the type, model and relevant parameter data of controllers;
• Real-time display the operational data and working status of the connection devices in digital, graphic and textual forms by a large-screen multifunction 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, and 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 connection devices;
• Longer communication distance based on RS485.

Main functions

Functions like the real-time monitoring of the operational data and working status of a controller, the browse and modification of charge/discharge control parameters, the setting of device parameters and load control parameters and the restoration of factory defaults, based on LCD display and functional key operation.

Recommendations

• Please confirm that MT50 is only allowed to connect with our LSxxxxB(P), VSxxxxBN and TracerxxxxBN(P) series controllers before purchase;
• Please do not install MT50 in a situation with strong electromagnetic interference.

-Night, Day: The threshold voltage is 1V. Higher than 1V is daytime.

Charge current icon
The icon is dynamically if there is charge current.

Battery icon
The battery capacity is dynamically displayed

Note: When the battery is in over discharge status, the icon displayed is "".

Battery status icons
-Normal voltage, -Under voltage, -Over discharge.

Load current icon
The icon is dynamically if there is discharge current.

Load status icon

-Load On, -Load Off.

Note: In Manual Mode, pressing the "OK" button will switch the load status between "ON" and "OFF"

Operation

Buttons

The buttons are respectively (from left to right) "ESC", "Left", "Up", "Down", "Right" and "OK "buttons, the operation is described in the schematic operation diagram below:

Schematic operation diagram
The default entry page is the browse mode. Pressing button and inputting the correct password to enter the modification mode; and buttons could be used to move the cursor, and buttons could be used to modify the parameter values when the cursor is located at the current place; and buttons could be finally used to respectively confirm and cancel the modification of the control parameters.

Main menu

Enter the Main Menu by pressing "Esc". "Up" and "Down" buttons are respectively used to move the cursor to select the menu items, "OK" and "ESC" buttons are respectively used to enter or exit the corresponding pages of the menu items.

Real-time monitoring

There are 14 pages under real-time monitoring. Please check it as below:

Operational tips:
Move between rows by pressing "Up" or "Down" buttons. Move along a row by pressing "Right" or "Left" buttons

Device information

The product model, parameters and SN code of the controllers are displayed below:

Operational tips: and buttons are respectively used to turn the browse page upward and downward.

Test operation

Load switch test operation is conducted on the connection solar controller to see if the load output is normal. The test operation does not affect the working settings under actual load, which means that the solar controller will exit from the test mode when exiting the operational interface of the test.

Operational tips: Enter the page and input correct password; use and buttons to modify the On/Off status values, while use and buttons respectively to confirm and cancel the test operation.

Control parameter

Browse and modification operations are conducted over the control parameters of solar charge controller. See the scope of parameter modification in control parameters table, and the page of control parameters in the diagram below:

Control parameters table

Battery voltage parameters
(Parameters is in 12V system at 25℃, please use X 2 in 24V, X 3 in 36 V, and X 4 in 48 V system)

Notes:

1. When the battery type is sealed, gel, flooded, the adjusting range of equalize duration is 0 to180min and boost duration is 10 to180min.
2. The following rules must be observed when modify the parameters value in user battery type (factory default value is the same as sealed type):
   1. Over Voltage Disconnect Voltage > Charging Limit Voltage ≥ Equalize Charging Voltage ≥ Boost Charging Voltage ≥ Float Charging Voltage > Boost Reconnect Charging Voltage.
   2. Over Voltage Disconnect Voltage > Over Voltage Reconnect Voltage
   3. Low Voltage Reconnect Voltage > Low Voltage Disconnect Voltage ≥ Discharging Limit Voltage.
   4. Under Voltage Warning Reconnect Voltage > Under Voltage Warning Voltage ≥ Discharging Limit Voltage.
   5. Boost Reconnect Charging voltage > Low Voltage Disconnect Voltage.

NOTE: Please refer to user guide or contact with the sales for the detail of setting operation.

Load setting

The page of load setting could be used to set the four load working modes of the connection solar controller (Manual, Light on/off, Light on+timer, Time control)

Manual control

Light On/Off

Light On+ timer

Time control

Device parameter

The software version information of solar charge controller could be checked via the page of device parameters, and device data like device ID, device LCD backlight time and device clock could be checked and modified. The page of device parameter in the diagram below:

Note: the bigger the ID value of the connection device, the longer the Meter communication identification interval (the maximum interval<6 minutes).

Device password

The password of the solar charge controller could be modified via the page of device password; the device password is a 6-digit figure which is required before entering the modification mode of "Control parameter", "Load setting", "Device parameter", "Device password", "Factory reset" pages. The page of device password in the diagram below:

Note: Solar charge controller default password is"000000"

Factory reset

The default parameter values of solar charge controller could be restored via the Factory reset page, which means the "Control parameter", "Load setting", "Charge mode" and "Device password" of the devices could be restored to the factory defaults (the factory default password of the devices is "000000").

Failure information

The current failure information of the solar charge controller could be checked via the Failure information page (a maximum of 15 failure messages could be displayed); when the failures of solar charge controller are eliminated, the corresponding failure information will also be automatically eliminated.

Meter parameter

The meter model, software and hardware version, and SN NO. could be checked via Meter parameter page. And the three parameters (Switch pages, Backlight, Audible alarm) could be browsed and modified as well.

Note: When the set up is accomplished, the auto switch page cannot become effective until ten minutes later.
