TriStar MPPT Controller


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. 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. 


Key Features and Benefits

  • Maximizes Energy Harvest
    • Better peak power point tracking than other MPPT controllers.
    • Very fast sweeping of the entire I-V curve.
    • Recognition of multiple power points during shading or mixed PV arrays.
    • Excellent performance at sunrise and low solar insolation levels.

  • Extremely High Reliability
    • Robust thermal design and no cooling fans.
    • Parallel circuit design provides less stress and longer life for electronic components
    • No mechanical relays
    • Extensive electronic protections including PV short circuit protection.
