Description Datasheet

TriStar 45 Amp 12/24/48 Volt MPPT Solar Charge Controller

Manufacturer Part Number: TS-MPPT-45

Morningstar’s TriStar MPPT solar controller (TS-MPPT-45) 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.

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
  • Epoxy encapsulated inductors and conformally coated printed circuit boards

Very High Efficiency

  • Peak efficiency of 99%
  • Proprietary tracking algorithm minimizes power losses
  • Low self-consumption

    5 of 5 Works GREAT! February 27, 2014
    Reviewer: Gary M from Sun City, AZ United States  
    From the moment I threw the switches to connect the batteries and the solar panels, this controller has worked flawlessly.  Really fast shipping!  I worried that I wouldn't need the latest MPPT technoligy but now watching how much more it charges in lower light conditions, I am very pleased that I paid the extra for the TriStar.  I only have 3 weeks use on it but am very pleased.

    4 of 5 Very good service and competitive Prices September 5, 2011
    Reviewer: Kelsey from Bellingham , WA United States  
    Thanks for your work on my charge controller.  I had left this purchase too late and I was headed up to our cabin to install a new Solar System but had forgotten to purchase the Charger.

    You were very good and got me the charger next day by making sure that the warehouse new it was important.

    Thanks for making my installation a success.
