Its robust construction and conformal coating on the circuit board enhance durability and protection against humidity. Common Questions What TriStar controllers is this meter compatible with? The TS-RM-2 is compatible with all Morningstar TriStar series solar charge controllers, including the original TriStar (TS-series), TriStar MPPT (TS-MPPT series), and TriStar MPPT 600V series. How long is the cable supplied with the meter? The Morningstar TS-RM-2 comes with a 30-meter (98.4 feet) RJ-11 communication cable, allowing for flexible remote mounting away from your charge controller. Can I monitor multiple TriStar controllers with one TS-RM-2? Yes, in multi-controller systems, the TS-RM-2 can be networked using an optional Morningstar MeterHub to display individual controller data and aggregate system data for up to 15 TriStar controllers. Can this meter be used to program the TriStar controller? No, the TS-RM-2 is designed for displaying information and initiating manual modes such as equalization. It is not capable of programming custom voltage setpoints or other advanced configurations, which are typically set via DIP switches on the controller itself. Installation Notes Mount the meter in a dry, protected location, away from direct sunlight or extreme temperatures, ensuring good ventilation. Ensure the 30-meter RJ-11 cable is routed safely, avoiding sharp bends, pinch points, or areas with potential electrical interference. Connect the RJ-11 cable directly to the designated MeterBus port on your Morningstar TriStar charge controller. Refer to the official Morningstar instruction manual for detailed mounting, connection, and operational guidelines. Before You Buy Verify that you own a Morningstar TriStar series solar charge controller (TS, TS-MPPT, or TS-MPPT-600V). Consider the 30-meter cable length to ensure it reaches your desired remote monitoring location. For monitoring multiple TriStar controllers, note that a Morningstar MeterHub (sold separately) is required. Ensure the chosen mounting location is suitable for the meter's dimensions (116 x 116 mm). Always verify product specifications and compatibility with your existing system components before purchase. This Morningstar TS-RM-2 meter is covered by a 5-year manufacturer warranty.
