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.


Maximizes Energy Harvest:

Our TrakStar MPPT Technology features:

  • 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
  • Epoxy encapsulated inductors and conform ally coated printed circuit boards


Very High Efficiency:

  • Peak efficiency of 99%
  • Proprietary tracking algorithm minimizes power losses
  • Low self-consumption
  • Continuous operation at full power to 45°C without need to de-rate
  • Selected electronic devices with higher ratings to minimize losses from heating


Extensive Networking and
