Product Specifications

Standard, DB, TR, and TR with GFPD versions shown
with optional display meters
• Adding modules incrementally with no string sizing issues
• Off-grid PV systems with input voltages greater than 150V
• Wind/hydro battery charging systems*
• 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
KEY FEATURES AND BENEFITS
¾ Maximizes Energy Harvest
Our TrakStarTM MPPT Technology features:
• Better peak power point tracking than other MPPT
charge controllers
• Very fast sweeping of the entire PV array
• Recognition of multiple power points during shading
or mixed PV arrays
• Low input voltage operation
• Excellent performance at sunrise and low solar
insolation levels
¾ Communications Capabilities
• Enables system monitoring, data logging and
adjustability. Uses open standard MODBUS™ protocol
and Morningstar’s MS View software
• Meterbus: Communications between compatible
Morningstar products
• Serial RS-232 and EIA-485 serial connectivity
• Ethernet: fully web-enabled interface to a local network
or internet; view from a web browser or send email
¾ Other Features
• High-Low voltage barrier improves safety
• Available with optional Disconnect Box: 600V PV
disconnect switch, battery breaker and prewired
input/output bus bars
• Available with DC Transfer Switch option for switching
from a GT string inverter to battery backup charging
during a utility outage. Multiple controllers and GFPDs
may be added later, on an as-needed basis
¾ High Voltage Capacity
• Maximum input voltage of 600V
• Operates with PV array Voc voltages up to 525 Voc
• Wind, hydro operating voltages up to 500 Vdc*
• Pre-set for 48 Vdc battery systems
• Programmable for 24V, 36V and 60V battery systems
• Allows long wire runs from the array to the controller
• Higher voltage reduces voltage drop and wire costs
• No combiner boxes required for single or two string
systems
• Better enables grid-tie PV systems with battery back-up
• Enables easier PV array expansion than lower voltage
systems and accommodates increasing loads
¾ Extremely High Reliability
• Robust thermal design and no cooling fans
• No moving parts
• Superior lightning protection from nearby lightning-
induced voltage/current spikes
• Extensive electronic protections
• Epoxy encapsulated inductors and conformally coated
printed circuit boards
¾ Very High Efficiency
• 97.9 % peak efficiency
• Proprietary tracking algorithm minimizes power losses
• Low self-consumption
• Continuous operation at full power to 45°C ambient
temperatures without need to de-rate
• Electronic devices with higher ratings to minimize losses
from heating
