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
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.
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.

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
The four channels provide up to four high level system control functions
at a lower cost compared to other alarm and generator start packages.
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.
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
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.
Displays power and status of each channel as well as faults and
data sampling intervals.
