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 loses significantly less power compared to other MPPT controllers. This particular model includes a remote temperature sensor.

The TriStar MPPT features “smart tracking” 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. The TriStar TS-MPPT enables system monitoring, data logging and adjustability. It has a meterbus for communications between compatible Morningstar products and a Serial RS-232 connection for personal computers.

This charge controller will require DC disconnects and typically a combiner box with fuses or breakers for wiring the PV input.
