Morningstar Tri-Star MPPT 45 & 60 Amp Charge Controllers
Morningstar TriStar TS-MPPT-45 and TS-MPPT-60 solar charge controllers are advanced technology maximum power point tracking battery chargers for solar PV systems up to 3,200 watts (3.2 kW) and a maximum open circuit voltage of 150 VDC. TriStar MPPT charge controllers have a maximum peak efficiency of 99% using a smart tracking algorithm that maximizes the the energy input from your PV array peak power point with extremely fast array and battery temperature monitoring. Why Use MPPT? MPPT charge controllers are amperage limited and solar array voltage tolerant. Increasing the solar panel array voltage by wiring panels in series keeps the amps down while increasing the volts. For example, an array of 12 solar panels each 250 watts 24 volts with maximum power point amps of 8.5 per panel wired 3 in series and four strings parallel inputs to the controller approximately 34 amps at 100 volts DC. This is a perfect situation for a TriStar 60 charging a 48 volt battery bank. Decreasing the battery bank voltage also decreases the PV watts capacity of the controller. Note: Attempting to charge a 24 volt battery bank with 24 volt array input is not recommended. During low solar energy conditions the array voltage may not meet or exceed the minimum charging voltage.

TriStar MPPT TS-MPPT-45 and TS-MPPT-60 comes with a RTS remote temperature sensor.
Morningstar’s MeterHub HUB-1 allows multiple Morningstar products to communicate over a Meterbus network to provide improved data monitoring, additional capabilities and lower system cost. Enables multiple controllers to share a single TriStar meter and display both single controller data (TriStar #1, TriStar #2…) as well as aggregated data for the entire system. Enables multiple controllers to share a single Relay Driver and fully utilize all 4 channels of the Relay Driver for different functions (alarms, load disconnects, generator starts) from multiple products. The MeterHub allows up to 15 Morningstar products on a single MeterBus network. The product electrically isolates devices that supply power to the network, preventing damage to the network in the event of grounding problems. Five status LED’s indicate the proper network connection to each port. The MeterHub is suitable for either wall or DIN rail mounting.
Morningstar’s Relay Driver is a logic module which provides high level system control functions such as high/low voltage alarms, load control and generator start. The product controls four independent relay driver outputs by reading digital data inputs from Morningstar’s TriStar controller or by reading battery voltage when used in systems with other controllers.
Morningstar’s EIA-485 / RS-232 Communications Adapter (RSC-1) enables networking capability by converting a controller or inverter’s RS-232 port to a standard EIA-485 serial connector. The RSC-1 may be used with any Morningstar controller or inverter equipped with a RS-232 port. By converting to EIA-485, the RSC-1 allows up to 128 Morningstar products to communicate on the same communication bus and over much greater distances. Typical configurations include: • Networking several TriStar and/or TriStar-MPPT controllers • Adding Morningstar’s PC Meterbus Adapters (MSC) for use with an RJ-11 port in multi-device networks. • Adding Morningstar’s Relay Driver to a network • Integrating any compatible Morningstar product into an existing EIA-485 network, such as those used by industrial control or SCADA systems. All data is transmitted in the form of MODBUS protocol. This industry standard was chosen for its robust design and high level of compatibility with a variety of equipment. Each Morningstar product has its own MODBUS specification (see our website for full details) that covers the data available from each products specific functions.
