Key Features and Benets
SOLAR CONTROLLER WITH MAXIMUM
POWER POINT TRACKING
Product shown with optional meter.
30, 45 or 60 amps
at up to 150 volts
open circuit
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 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.
