Morningstar TriStar TS-MPPT-60-600V-48-DB-TR Solar Controller with DC Transfer Switch

$ 1,231.00

The Morningstar TriStar TS-MPPT-60-600V-48-DB-TR Solar Controller with DC Transfer Switch can be used with higher voltage photovoltaic (PV) arrays, wind turbines or hydropower systems. This product enables the following application scenarios: • Adding modules incrementally with no string sizing issues • Off-grid PV, wind or hydro systems with input voltages greater than 150V • Fewer combined circuits and lower current for long wire runs from the array to the controller • New installation grid-tie PV systems with battery back-up • Retrofitting grid-tie PV systems to include battery back-up without changing the PV array configuration • Supplementary charging for AC Coupled PV systems



The Morningstar TriStar TS-MPPT-60-600V-48-DB-TR Solar Controller with DC Transfer Switch with TrakStar Technology™ is an advanced maximum power point tracking (MPPT) battery charger for off-grid photovoltaic (PV) systems up to 3kW. The Morningstar TriStar TS-MPPT-60-600V-48-DB-TR 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. Maximizes Energy Harvest Our TrakStar MPPT Technology features: • Better peak power point tracking than other MPPT controllers • Very fast sweeping of the entire I-V curve • Recognition of multiple power points during shading or mixed PV arrays • Excellent performance at sunrise and low solar insolation levels Extremely High Reliability • Robust thermal design and no cooling fans • Parallel circuit design provides less stress and longer life for electronic components • No mechanical relays • Extensive electronic protections including PV short circuit protection • Epoxy encapsulated inductors and conformally coated printed circuit boards Very High Efficiency • Peak efficiency of 99% • Proprietary tracking algorithm minimizes power losses • Low self-consumption • Continuous operation at full power to 45°C without need to de-rate • Selected electronic devices with higher ratings to minimize losses from heating
