MorningStar TriStar PWM Solar Charge Controllers

The MorningStar TriStar PWM Solar Charge Controllers Pulse-Width Modulation (PWM) controller for larger systems, providing reliable PWM solar battery charging or load control or diversion regulation. PWM technology controllers are ideal for use in solar energy situations where 36 or 72 cell PV modules are available and the site is unshaded with no physical space limitations. TriStar models incorporate advanced thermal design requiring no cooling fans, which ensures long-term reliability with no moving parts to fail– a unique feature among higher- powered controllers.

• Built for reliability and performance, with an oversized heatsink and over-spec’d components
• More information with LED indicators. Optional meter displays extensive system and controller
  information in five languages; automatic self-test and reset communications capability with
  RS-232 port, connects to a PC for custom settings, data logging, remote monitoring and control
• “Speaks” Modbus, and also SNMP (with the optional EMC-1 adaptor) for monitoring and
  control in network applications
• Extensive electronic protection against reverse polarity, short circuits, overcurrent, and
  excessive temperature
• Detailed battery programming options allow for advanced battery support for the latest
  Lithium, Nickel Cadmium, and Lead Acid battery types.
