Installation
WARNING: BEFORE drilling, make sure there are no electrical components or other obstacles
that may interfere with installation on the other side of the mounting surface.
CAUTION: Before installing the MT-50, apply power and make sure the meter is working properly.
Resolve any issues before installing the meter and the meter cable.
The MT-50 can be mounted in two ways: Frame Wall Mount or in a Flush Wall Mount. A plastic
mounting frame has been included for the purpose of Frame Wall Mounting. If Flush Wall
Mounting then the MT-50 faceplate sits flush with the mounting surface and the body of the meter
would be able to rest comfortably in a hole cut-out on the mounting surface.
Frame Wall Mount Installation
When frame mounting, the MT-50 Tracer will be utilizing
the provided frame and be mounted on a wall or surface.
No cut-outs are required for the surface with the
exception of the 4 x screw holes.
1. Locate and drill the screw holes based on the
mounting frame dimension and erect the plastic
expansion bolts on the wall.
2. Use 4 x ST4.2x32 self-tapping screws to fix the
frame.
3. Use 4 x M4x8 pan head screws to mount the MT-
50 front to the frame
4. Mount the 4 associated screw plugs into the screw
holes
5. Plug the meter in and verify the meter powers up
and displays the appropriate data. Troubleshoot if
necessary.

6
Flush Wall Mount Installation
This is a low-profile installation. The faceplate of the MT-50 sits flush with the mounting surface
or wall and the body of the meter rests in a hole cut-out on the mounting surface. The meter
wiring is concealed behind the mounting surface, or the interior of the wall.
1. Locate and drill screw holes based
on the installation size of the surface.
Level the faceplate and remove a
hole-cutout.
2. Use 4 x M4x8 cross recessed pan
head screws with the M4 nuts to
mount the MT-50 surface onto
surface.
3. Mount and use white plugs in the
screw holes.
Operation
NOTE: The MT-50 is not compatible with the Commander 60A charge controller.
The following keys are used to cycle through the screens or adjust the parameters on the tracer:
Once the Tracer Meter is connected, the user will see welcome screen followed by a device info
screen, before settling on the Default Screen.

In Light On/Off the user sets to loadto be operated
by the time of day.
The load terminal automatically turns ONwhenthe
solar voltage goes BELOW the point of NTTV
(Night Time Threshold Voltage).The load
automatically turns OFF when the voltage goes
ABOVE the point of DTTV (Day Time Threshold
Voltage). There is a delay between turning the
load on or off and can be programmed to be from
0-99minutes.
NOTE: Minimum and maximum charge parameter
values can be found in Technical Specifications
Similar to Light On/Off parameter with the addition
of a timerthat the user sets in order to indicate how
long a load will be on or off. The user also sets an
appropriate time for when it is night time.
Nightime12 indicates the remaining time between
the Load being on and off
NOTE: Timer needs to be activated for it to work
Using a 24-hour clock, the user is able to set the
time for when the load will turn on and the time for
when the load will turn off. The system works fine
with just one timer, the second timer serves the
purpose of dual functioning. For example, if the
user wants to turn the load on and off within 3
hours of night time and turn the load on and off
again before sunrise they will be able to with a dual
timer.

Troubleshoot
Load MOS-Short
Reset the controller to factory settings. If problem persists,
contact supplier.
Load Circuit
Load circuit is short. Check the device wiring and connections
going into the load. There may be a break in the wire.
Load O. cur.
Load is overcurrent. Check to make sure the devices connected
to the load terminal are within the load specification. If so, then
reduce the number of loads and it will reconnect automatically.
Input O. cur.
PV terminal overcurrent. Use a multi-meter to determine whether
solar panel(s) specification match the nominal parameters of the
charge controller.
RPP Short
Check connections to make sure they are not reverse. Reset the
controller to factory settings. If problem persists, contact the
supplier
RPP Break
Reset the controller to factory settings. If problem persists,
contact the supplier
Char.MOS-Short
The charge driver is short. Reset the controller to factory
settings. If problem persists, contact the supplier

17
Disc.O.O.Ctrl.
Check that the battery connections are properly connected to the
battery terminals of the charge controller. Make sure there is no
short along the line. Reboot the controller. If problem continues,
reset the controller.
Ctrler O.Temp.
Controller Over temperature. Place the controller in a cooler
environment where it will automatically reconnect.
Comm. Timeout
Error with the communication port. Check controller connection
and reboot device.
Device Considerations
Warning Indicator
The red LED on the tracer will turn on where there is an issue. Check the Failure
Information Log first. The following are possible reasons for the warning indicator
1. One battery could be disconnected, over voltage, or open circuit. Check
connections. Disconnect and reconnect.
2. The remote temperature sensor probe is malfunctioning. Check the sensor probe.
Disconnect and reconnect.
3. The system is experiencing overcharging current. Check connections, disconnect
and reconnect
4. Solar PV is short circuited. Check connections, disconnect and reconnect.
Telecommunication Port
When the meter running on individual power or the communication is cut off, the MT-50 will
display graphical symbols abnormally. Press any key to stop the display and resume normal
activity. If problem persists, disconnect the port and connect it again. Normal behavior is when
the meter updates every 20 seconds.
NOTE: Errors could occur in the telecommunication port if the connection is not properly
secured. Also, too long of a cable may cause some inconsistencies.
Battery Level Flashing
The meter measures battery capacity by the voltage it is experiencing. When batteries are
charging, they will not necessarily match the accurate battery capacity.
Battery capacity AH
AH is the accumulation of charging, each one minute will count. The data is not accurate while
the charge current is too small. The min. is 1AH, means 1 amps charging for 1 hour, Ah comes
to show.

Troubleshooting
MT-50 has no display
•Verify the charge controller is powered on and that it is securely connected to the MT-50.
LCD display is dim
•Check the system battery voltage. The MT-50 needs a minimum of 8 V to operate.
•Verify that the temperature is within range of the LCD operating parameters.
MT-50 turns on, but shows no data
•MT-50 is potentially damaged or the cable is damaged. Replace the cable by contacting
the manufacturer.
MT-50 display does not match product manual
•Our products undergo manual revisions from time to time. Please check our website at
Renogy-store.com > downloads for latest documentation.
Buttons do not work
•Disconnect the MT-50 and clean the faceplate to remove any potential buildup of residue
•Reconnect MT-50
