Morningstar’s TriStar MPPT solar controller with TrakStar Technology™ is an advanced maximum power point tracking (MPPT) battery charger for off-grid photovoltaic (PV) systems up to 3kW. Both controllers 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% and significantly less power loss compared to other MPPT controllers. The TriStar MPPT features a smart tracking algorithm that maximizes the energy harvest from the PV by rapidly finding the solar array peak power point with extremely fast sweeping of the entire I-V curve. This product 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 provide detailed operating data, alarms and faults and three LED’s display system status.
Additional networking options are available. The MeterHub allows multiple Morningstar products to communicate over a Meterbus network to enable multiple controllers to share a single TriStar meter and display both single controller data as well as aggregated data for the entire system.
Terminals accept up to 2 gauge wire.
