MorningStar Tristar MPPT Charge Controller

The Morningstar TriStar MPPT charge controller’s advantage over traditional controllers is higher energy harvesting from the solar array, achieved by pulling the energy out at a much higher voltage. You can wire the solar array at 150VDC to charge a 12, 24 or 48V battery. This also allows the array cable to be smaller, the array to be placed further away and higher voltage panels to be used.

Key features and benefits

  • Maximizes energy harvest – superior peak power tracking over
    conventional MPPT controllers.
  • Highest peak efficiency for off-grid controllers in the industry: 99% (TS150).
  • Built for reliability and performance, with an oversized heatsink and
    over-spec’d components. Fully-rated for operation at temperatures up to 45C.
  • Extensive networking and communications features enable system
    monitoring, data logging, and adjustability.
  • On-board RS-232 port included on all models; Ethernet included on all 60A models.
  • Extensive electronic protections include short-circuit, over-current and reverse polarity to ensure the controller will not be damaged by wiring mistakes or overloads.
  • Certified to IEC 62093 which establishes requirements for the design qualification of balance-of-system (BOS) components used in terrestrial photovoltaic (PV) systems.
  • Fanless design for long-term reliability
