The EcoBoost MPPT™ solar charge controller brings Morningstar’s proprietary TrakStar Technology™ to our new line of Essentials controllers and accessories. The EcoBoost controllers automatically detect 12 or 24 V system configuration. They are highly efficient and accurate controllers designed to ensure that batteries attain a complete state of charge. They are also sophisticated load controllers. Using this feature to manage DC power consumption protects the batteries from over discharge and helps ensure long term system reliability. Small DC loads can be powered directly from the EcoBoost by way of two USB charging ports.

Morningstar EcoBoost controllers act as the central brain of PV powered DC electrical systems up to 1,120 watts and offer outstanding value, performance and dependability.
