Description Datasheet

Morningstar Digital Meter 2

Manufacturer Part Number: TS-M-2

This meter is for displaying controller information or starting manual modes such as equalization. It is NOT capable of programming the controller, such as custom voltage setpoints. This is done with DIP switches inside the controller.

Displays a full range of operating and diagnostic information for the TriStar PWM and TriStar MPPT battery charging, load, and diversion operating modes. The TriStar meters can be added to the controller when it is first installed, or at anytime after the controller has been in service.

Morningstar’s TriStar Meter-2 (TS-M-2) and TriStar Remote Meter-2 (TS-RM-2) are advanced digital meters that may be used with any TriStar solar controller. These two meters are identical except that the TS-M-2 is mounted on the controller and the TS-RM-2 is flush mounted up to 30 meters (98.4 feet) away from the controller.


Easy to Install

  • Uses standard 6 conductor RJ-11 connectors.
  • Both data and meterbus power flow over a single cable.
  • Network supports up to 15 devices and, optionally, more than one meter per system.

Easy to Use

  • Four directional pushbuttons for easy navigation of display screens.
  • Backlighting to enhance readability.
  • Meter may be added during initial controller installation, added as an upgrade anytime in the future or connected temporarily for troubleshooting and then using this same meter at other sites.

Networking Capability

  • Displays individual controller data from up to 14 TriStars with optional Morningstar Meterhubs.
  • Aggregates system data to show total charge, load and battery charge/discharge state.
  • Auto detects any device found on the network.

Detailed Description

The meter will display a great deal of information about the TriStar controller and the operation of your system. In addition, the meter enables manual functions and controller diagnostics. These capabilities will increase your confidence that the system is working properly and will help you to improve system reliability, battery life, and system performance. It is worth the time getting to know your meter!

The TriStar meters are 2 x 16 character LCD’s that display extensive system and controller information, logged data, bar graph metering as well as alarms and faults for easy troubleshooting. The information may be shown in English, French, German, Portuguese or Spanish languages.

In multi-controller systems the TS-M-2 and TS-RM-2 are networkable using Morningstar’s MeterHub to allow individual controller data and aggregate system data to be displayed together on a single meter.

Connected to a TriStar Controller

Battery voltage, charge/load current, battery temperature, TriStar heatsink temperature, PWM duty cycle, PV/load voltage, and all TriStar alarms or faults.

Used in Systems with Other Controllers

Battery voltage, Relay Driver temperature, input voltages from other sources.

Cost Effective

The four channels provide up to four high level system control functions at a lower cost compared to other alarm and generator start packages.

High Reliability

Each channel has complete electronic protections for high reliability.


The system designer may choose the exact relay needed for each application including a wide range of current ratings and solid state, mechanical or mercury displacement relays.

Fully Programmable

It is easy to program the Relay Driver with the included PC software via serial RS-232 port connection. Data is stored in non-volatile memory. The Relay Driver is pre-programmed with four commonly used settings.

Advanced Generator Control

Provides flexible parameters to control one, two or three-wire generator schemes and complete control of preheat, crank, ignition and cool-down.

Industrial Design

Each relay driver output may be controlled directly by MODBUS commands via the RS-232 for use with PLC’s and other industrial hardware. Mounts to a DIN rail or a flat surface.

LED Indicators

Displays power and status of each channel as well as faults and data sampling intervals.

5 of 5 Tells the history May 30, 2014
Reviewer: Fred Richards from Petersham, MA United States  
This meter gives much more information than three led lights. If you need to evaluate how your solar system is working, try one.

5 of 5 Great Information! February 27, 2014
Reviewer: Gary M from Sun City, AZ United States  
This meter give way more information that just the 3 lights that the controller comes with.  I can watch a host of information, as well as do really easy troubleshooting.  That is, if anything goes wrong, which it hasn't as of this review.  Extremely pleased with the Digital Meter, worth the extra money for it.
