Description
Morningstar TriStar Digital Meter-2 (TS-M-2)
Overview
The TriStar Digital Meter-2 adds on-controller, backlit LCD monitoring to Morningstar’s TriStar PWM and TriStar MPPT systems. With a 2×16 character display and four-button navigation, it surfaces live charge/load/battery data, cumulative Ah/kWh totals, and active/latched alarms—speeding commissioning and field diagnostics. A single RJ-11 MeterBus cable carries both power and data, and with Morningstar’s MeterHub you can view aggregate values across multiple networked TriStar controllers.
Key Features
- Real-time readouts for controller status, battery/array metrics, and logged totals
- Backlit LCD, four directional keys, multilingual UI (EN/FR/DE/PT/ES)
- MeterBus (RJ-11) single-cable data + power; auto device discovery
- Works in networks of multiple TriStar controllers via MeterHub
- Companions: TS-RM-2 remote/flush-mount version; TS-M-2-600V for TriStar MPPT-600V
Applications
- On-panel visibility for off-grid solar, telecom, and industrial control systems
- Field service and troubleshooting across multi-controller arrays
- Centralized metering of distributed TriStar installations

Design & Operation
Installs directly onto the TriStar chassis (or remotely via TS-RM-2). The meter’s low power draw preserves system efficiency while giving immediate access to live performance, cumulative energy, timers, and diagnostic history. Ideal for permanent installs or as a roving service tool reused across sites.
