Morningstar’s TriStar TS-MPPT solar controller with TrakStar Technology are advanced maximum power point tracking (MPPT) battery chargers for photovoltaic (PV) systems up to 3kW. It can be used with arrays with a maximum open circuit voltage of 150 VDC and charge batteries between 8 and 72 VDC. A remote temperature sensor is included.
The controller provides the industry’s highest peak efficiency of 99%. It also has significantly less power losses as compared to other MPPT controllers. The TriStar MPPT features TrakStar Technology and smart tracking algorithms that maximize the energy harvest from the PV array by finding the array’s peak power point with a fast sweeping of the entire I-V curve. Extensive networking and communications capabilities enable system monitoring, data logging and adjustability.
TriStar controllers offer open standard MODBUS protocol and Morningstar’s MS View software. Additionally TriStar TS-MPPT models offer Meterbus communications between compatible Morningstar products, and allow Serial RS-232 connection to a personal computer. They are ETL Listed to UL 1741 and come with a 5-year warranty.
The TS-MPPT is the first PV controller to include on-board Ethernet for a fully web-enabled interface and includes up to 200 days of data logging. Optional TriStar meter and remote meter provide detailed operating data, alarms and faults and three LED’s display system status. The chassis on the TriStar TS-MPPT controllers is isolated from the power circuits, allowing use in both negative and positive grounded systems.
