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 conform ally 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.
