Introduction

Morningstar’s TriStar MPPT solar controller with TrakStar TechnologyTM 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.

General Description

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

Using TrakStar MPPT technology to determine and adjust to the true maximum power point as solar insolation changes throughout the day.

Built for reliability and performance,

with an oversized heatsink and over-spec’d components. Fully rated for operation at temperatures up to 45C.

Extensive electronic protections

Include short-circuit, over-current and reverse polarity to ensure the controller will not be damaged by wiring mistakes or overloads.
