    TriStar MPPT 600V

    Morningstar’s TriStar MPPT 600V charge controller (TS-MPPT-600V) is a brand new addition to our world-leading TriStar MPPT solar controller family, which was first introduced in 2009 and has become the MPPT controller of choice for many large, global, off-grid PV applications. The TS-MPPT-600V leverages Morningstar’s innovative TrakStar™ MPPT technology and our 20+ years of power electronics engineering excellence, to deliver the widest PV input operating voltage range available in a PV controller. Morningstar’s TrakStar MPPT technology enables the TriStar MPPT 600V charge controller to harvest the maximum energy from the solar array or wind turbine. The high-speed sweeping algorithm minimizes power loss and provides full visibility of the entire power curve from open circuit to battery voltage; ensuring the maximum power point is chosen under all ambient conditions. The TriStar MPPT 600V charge controller uses advanced power electronics to efficiently utilize up to 600 Voc (open circuit voltage) PV or wind to charge 48 Vdc battery systems. Rated for 60 Amps, our TriStar MPPT 600V controller does much more than efficiently charge batteries; it also provides remote communications, data logging, adjustability and metering. In fact, the TriStar MPPT 600V controller is the only 600-volt PV controller to offer open communication protocols and true Ethernet-enabled functionality. The TriStar MPPT 600V charge controller may be purchased with or without a pre-wired DC Disconnect Box. The pre-wired DC Disconnect Box version (model TS-MPPT-60-600V-48-DB) is acceptable for use with positively-grounded or negatively-grounded PV systems and helps to save on installation time and cost. Key Features & Benefits Morningstar’s products are built from the inside out to deliver more than twice the industry average operating life. The TriStar MPPT 600V charge controller delivers high reliability and excellent performance and features: The industry’s best-in-class power efficiency. Morningstar’s advanced 4-stage charging algorithm to optimize battery health Robust thermal, mechanical and electrical design Environmentally optimized and equipped with extensive electronic protections Industry standard open communication protocols and interfaces for system networking, monitoring and communications Superior lightning protection from nearby lightning-induced voltage/current spikes Applications The TriStar MPPT 600V charge controller’s high voltage capability and flexible design enable several application scenarios including: Off-grid PV systems greater than 150 Voc with long wire runs from the array to the controller New installation grid-tie PV systems with battery back-up Retrofitting string PV inverter systems to later add battery back-up without changing the PV array configuration Battery-based Wind systems

    Ground Fault Protection Device

    Morningstar’s Ground Fault Protection Device products are built to provide a superior solution to ground fault protection for both off-grid and on-grid PV systems. The GFPD products’ are available in two model versions (GFPD-150V and GFPD-600V) to support 150V and 600V PV system breaker stacks. Morningstar’s GFPD increases safety and design flexibility in off-grid and on-grid PV systems. Ground fault protection is used in electrical systems to prevent current from following any unintended paths during a ground fault. It is critical to detect any stray current and to interrupt (break) the circuit until safe operation can be restored. A current imbalance between the conductors of a circuit indicates a ground fault. When a ground fault is detected, Morningstar’s GFPD breaks the circuit on both the positive and the negative legs and ensures interruption of the ground fault current better than other solutions on the market. Key Features & Benefits Maintains the integrity of earth bond for battery and loads. Trips at lower fault current with greater accuracy. Breaks both conductors in the faulted circuit and completely isolates PV source circuits. Does not require an extra warning label at the battery as per U.S. National Electric Code requirements. Provides design flexibility to meet a wide range of configurations: Positive and negative ground Large and small arrays Makes it easier to locate and troubleshoot ground faults. Powered via the PV system’s battery bank. Equipped with both visual and audible alarms. Built to support both single controller and multiple controllers systems: Morningstar’s GFPD will only shut off affected controllers, while maintaining the system earth bond. All loads will continue to operate safely with the battery remaining bonded Multiple controllers and GFPDs can be added on an as-needed basis
