Description
Morningstar TriStar™ MPPT Solar Charge Controller
The Morningstar TriStar™ MPPT with TrakStar Technology™ is a high-performance maximum power point tracking (MPPT) controller for off-grid PV systems up to 3 kW. Delivering peak efficiencies of up to 99%, it significantly reduces power losses compared to other MPPT controllers.
With an advanced tracking algorithm, the TriStar MPPT rapidly scans the entire I-V curve to find and maintain the true maximum power point—even in shading, mixed arrays, or low-light conditions. It is also the first PV controller with built-in Ethernet, providing a fully web-enabled interface along with up to 200 days of onboard data logging.
