Morningstar TS-MPPT-45 TriStar Charge Controller, 45A, 150VDC, 12 to 48 VDC, with RTS, MPPT

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

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 conformally 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 Communications Capabilities

Enables system monitoring, data logging and adjustability. Uses open standard MODBUS™ protocol and Morningstar's MS View software.

  • Meterbus: communications between compatible Morningstar products
  • Serial RS-232: connection to a personal computer
  • EIA-485: communications between multiple devices on a bus
  • Ethernet: fully web-enabled interface to a local network or internet; view from a web browser or send email/text messages

Metering and Data Logging

  • Optional TriStar meter and remote meter provides detailed operating data, alarms and faults. (Image shown with Digital Meter - not included)
  • Three LED's display system status
  • Up to 200 days of data logging via meters or communications ports
