Collection: Morningstar

These powerful tropicalised three-function PWM controllers provide reliable solar battery charging, load control or diversion regulation to divert excess power to a dump load for use in solar, wind or hydroelectric systems. (Two or more controllers may be used to provide multiple functions). Large heat sink enables operation at up to 45°C without de-rating. 3 LED's indicate battery status, alarms and faults. Optional LCD digital backlit display (included with -M version) provides system & controller information: battery voltage; current; temperature; amp-hours and error mode. Versions mount either on face of the controller or remotely. For use in either 12, 24 or 48V systems. Fully adjustable with DIP switches. RS232 communication for custom settings, data logging, remote monitoring/control. Reverse polarity, short circuit, over-current, high temperature and over-voltage protection. Operation from - 40 to+ 45°C. Terminals take up to 35sqmm cables.

These are the ideal controller for small professional and consumer systems. Fully encapsulated, they are approved for hazardous locations.

Morningstar’s PC MeterBus Adapter converts a controller’s MeterBus RJ-11 to a standard RS-232 serial connector for connection to a PC or other equipment. The MSC may be used with any Morningstar controller or inverter equipped with a meter connection that does not also already have a RS-232 port. Communications link enables monitoring and logging of data as well as customizing of set points.

These are simple controllers which mount directly to the solar module junction box and eliminate the need for additional controller housing. Fully encapsulated and IP65 outdoor rated, they are approved for hazardous locations and high temperatures (up to 70°C). Connection is via flying leads. Use with sealed or vented batteries is field selectable. 12V. Bi-colour LED indicates charging, operation & faults.

The industry-leading TriStar MPPT with TrakStar Technology is an advanced maximum power point tracking controller for larger off-grid photovoltaic (PV) energy systems up to 4.2kWp. An iconic design, TriStars have been proven in solar installations around the globe and remain the first choice for designers of mission-critical systems where failure is not an option.

This is the ideal controller for one-module systems. Fully encapsulated in epoxy potting, they can be mounted in battery enclosures and are weatherproof. Connection via 200mm leads.

Improves battery charging by using temperature at the battery for very accurate temperature compensation. (Included with TS-MPPT)

The Prostar MPPT™ solar charge controller uses TrakStar Technology™ for advanced maximum power point tracking (MPPT) battery charging. Suitable for Lithium, Nickel Cadmium, and Lead Acid battery types.

The EcoBoost MPPT™ solar charge controller brings Morningstar's proprietary TrakStar Technology™ to their Essentials controllers and accessories.

Digital displays to provide system and controller information, data logging, alarms and errors.

These low-cost controllers are ideal for small lighting systems. High reliability with built in electronic fuses. Circuit boards are coated for protection against humidity & insects. LED's indicate battery level and system status. 12V.

The MeterHub supports the connection of up to 15 Morningstar products on a single MeterBus network. It electrically isolates the devices that supply power to the network to prevent damage in the event of grounding problems. Five status LED’s indicate the proper network connection to each port.
