45A Solar Controller with Maximum Power Point Tracking

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.

The TS-MPPT-45 can be used with 12, 24, 36, and 48-volt DC battery systems and is able to charge a lower nominal-voltage battery from a higher nominal-voltage array.
