TriStar MPPT 60A

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.
