This feature assists users in quickly troubleshooting potential issues within their solar charging setup, contributing to reliable system operation.
Compatibility & Connection
The MT50 Remote Meter is designed for seamless integration with a range of MPPT and PWM solar charge controllers. Compatible series include:
- TR and PTR series: Models TRxxxxBN, TRxxxxAN, and PTRxxxxAN.
- VS Series: Models VSxxxxBN.
- PU series: Models PUxxxxB.
- PU series waterproof: Models PUxxxxBW (requires a specific compatibility cable).
- LS Series.
Connection: For controllers with an RJ45 port, simply plug in the included 5-meter RJ45 cable. For controllers equipped with an RS485 port, an additional RS485 to RJ45 cable will be required for connection (not included).
Please Note: This Remote Meter/Display is not suitable for dual battery solar charge controllers (DB or EPIPCOM series), or for eTracer 45A/60A solar charge controllers.
Common Questions
What information can I monitor with the MT50?
The MT50 allows you to view real-time charging parameters such as solar panel voltage and current, load current, battery voltage, and battery state of charge. It also logs accumulated charge/discharge energy and min/max voltages.
Can I change battery settings using this display?
Yes, the MT50 unlocks advanced settings on compatible controllers, allowing you to amend battery type, capacity, charging voltages for different stages, and even create user-defined battery types.
Is the MT50 difficult to install?
Connection is straightforward using the included 5-meter RJ45 cable for compatible controllers. It offers flexible mounting options for either flush or surface installation. A detailed user manual is provided for guidance.
What if my controller has an RS485 port?
If your controller has an RS485 port instead of an RJ45, an additional RS485 to RJ45 cable will be required for connection. This cable is not included with the MT50.
Installation Notes
- Refer to the included user manual for detailed connection steps and operational instructions.
- Ensure the correct port (RJ45 or RS485 with adapter) is used for connection to your solar charge controller.
- For flush-mounting, a suitable recess will be required in your chosen mounting surface.
- Position the meter in a location that is easily accessible for monitoring and protected from direct sunlight or extreme temperatures.
Before You Buy
- Verify your solar charge controller model is listed as compatible (TR/PTR/VS/PU/LS Series).
- Confirm the type of communication port on your controller (RJ45 or RS485) to ensure you have the correct cable.
- Note that this meter is not compatible with dual battery controllers (DB/EPIPCOM series) or eTracer 45A/60A models.
- Consider your preferred mounting method (flush or surface) and prepare the installation area accordingly.
Always verify product specifications and compatibility with your existing solar system components before purchase. This product is covered by a 1-year manufacturer warranty.
