TriStar MPPT

The industry-leading TriStar MPPT™ with TrakStar Technology is an advanced maximum power point tracking controller for larger off-grid photovoltaic (PV) energy systems up to 3kWp. An iconic design, TriStars have been proven in solar installations around the globe and remain the first choice for designers of mission-critical systems where failure is not an option.

“one of the best charge controllers out there… these things are tanks”

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
  1. Premium high-frequency CoilCraft surface mount indicators
    They’re worth it, because they provide the faster power «tracking» that lets us engineer this much power and control into a compact design.
  2. High-frequency design
    Combined with premium, «over-spec’d» components, this greatly improves control response which guards against system transients, regulation overshoot and overcurrent/overload conditions
  3. Large diameter, high torque, corrosion resistant terminals
    If you’ve ever trashed a lesser terminal during an installation, you’ll appreciate some «overkill» here
  4. DirectFET™ MOSFET power devices
    Allows the surface-mounting of critical components underneath the main board next to the heat sink, which reduces heat travel distance and keeps the controller even cooler
  5. Highly-conductive aluminum heatsink extrusion
    As opposed to cast aluminum, which is less effective in passive cooling applications
  6. Communications/data port with serial/meter auto detect
    «Talks solar» with standard industry language, for system monitoring and cloud connectivity-speaks Modbus, and SNMP (with the EMC-1)
  7. Lithium foldback circuit
    Lithium batteries are expensive and vulnerable to cold temperatures. When it gets close to freezing, the controller backs-off charging to avoid damaging batteries
  8. High-speed ARM processor
    All-digital calibration for high accuracy, using the same efficient technology found in advanced mobile devices
  1. Large format, high-resolution backlit LCD
    When you’ve been in the field installing, you appreciated being able to read a crisp, high contrast display on site
  2. Lexan polycarbonate UL listed case
    Protects the precision electronics inside with an impact strength 30 times greater than the acrylic thermoplastics commonly found on lesser controllers
  3. High temperature architecture
    Heat is the enemy of all electronics. That’s why Prostar’s critical components are rated to withstand temperatures right up to the boiling point of water (100°C)
  4. 5 year warranty
    Up to 2 1/2 times longer than some competitors in this class
  5. Cooling Fan
    Just kidding. We’ve never needed them
  6. Self-diagnostics
    ProStar is smart enough to monitor and analyze system performance, and alert you when you need to know
  7. TrakStar™ Technology
    Morningstar’s hallmark MPPT technology precisely seeks and locks onto the true maximum power point quickly and accurately, to ensure the highest output possible from a solar array

System Diagrams

    Off-Grid Diagram with DC Load

The schematic diagram above, illustrates how the ProStar MPPT regulates power to batteries and a direct current (DC) load in an off-grid system.

  1. Sunlight contacts the solar modules, which convert solar into DC electrical power that it delivers to a charge controller.
  2. The charge controller regulates the amperage and voltage that is delivered to the loads and any excess power is delivered to the battery system so the batteries maintain their state of charge without getting overcharged.
  3. During the evening when there is no sunlight, battery power is used to run the load.

 


 

    Off-Grid Diagram with AC Load


The schematic diagram above, illustrates how the ProStar MPPT regulates power to batteries and an alternating current (AC) load in an off-grid system.  This diagram is very similar to the DC load diagram above it except an inverter has been added.

  1. Sunlight contacts the solar modules, which convert solar into DC electrical power that it delivers to a charge controller.
  2. The charge controller regulates the amperage and voltage that is delivered to the battery system so the batteries maintain their state of charge without getting overcharged.
  3. Batteries deliver power to the inverter which converts DC to AC power that it delivers to the load.  Notice that  the inverter is connected to the battery, not the controller’s load terminals, like we did in the DC load example.  That’s because the inverter can have a high energy surge upon start up, and this high current surge might be higher than the rated capacity of the charge controller, whereas the batteries will be able to meet the high energy surge requirement.
