    Products: TriStar TS-MPPT-60, TriStar TS-45, Relay Driver RD-1, Communications
    Adapter (RSC-1), TriStar Digital Meters TS-M-2
    System size: 5.84kW of solar and 1,075 Ah/48V battery bank
    Partners include: SunWize, Commdex

    The use of wireless communication is expanding rapidly both in the United States and across the globe. From critical government closed-loop communication systems to last-mile rural ISPs for end-users, wireless data transmission has become a critical layer of our industrial infrastructure. Wireless communications technology makes it possible to “leapfrog” the running copper lines and networks, greatly reducing the time and cost it once took to deliver services to remote users. Because of this, wireless infrastructure is often placed in rural or remote locations without access to grid power. Lake Mead National Recreation Area has a primary remote communication site located at Mount Perkins in Mohave County, Arizona. SunWize provided a hybrid system to power this equipment, consisting of a solar electric system and backup generator designed to support continuous operation of a 472W load. Output voltages of +12Vdc, +24Vdc, and -48Vdc accommodate different onsite equipment. Requirements include operation at temperatures up to 130° F, components rated to withstand 90+ mph wind speeds, PE stamps on drawings, adherence to applicable NEC and IEEE standards, UL-certified components, VRLA batteries, and SNMP communication on the controller. In addition to the Morningstar components used, battery charging from the solar array is complemented by x2 Meanwell DBU 3200 battery charging units providing 110A of rating input at 48Vdc. All equipment is contained within a compact, durable enclosure.

  • Lifeline Telecom Services in Central Oregon

    Application: Telecom
    Location: Oregon
    Year: 2012
    Product: TriStar MPPT
    System size: Two 235-W solar panels
    Partners include: Rural Technology Group, SolarWorld

    A Morningstar TriStar MPPT controller helps distribute internet services to a rural community in Central Oregon where many residents live without a telephone or cell service. Morningstar partnered with Rural Technology Group for an experimental project to expand internet service in rural areas with rugged terrain. 

    The team successfully installed a solar-powered microwave relay site on top of a mountain. A high-speed connection VOIP service now gives the community access to lifesaving emergency calls. 

    So far, the project has survived hurricane-strength winds, periods of dark and snowy days and temperatures in excess of 105°F to -4°F (41°C to -20°C). This relay also cost less than $3,500 to construct and commission.

  • Reliable Power to Detect Earthquakes and Other Seismic Events

    Application: Telecom
    Location: Oregon and Washington
    Product: Sunsaver MPPT
    Partners include: The Pacific Northwest Seismic Network

    Unlike severe weather, which can be tracked and mapped for days and even weeks before landfall, earthquakes appear suddenly and without warning. Advances in technology now allow detecting earthquakes within life-saving seconds before shaking has begun.

    The Pacific Northwest Seismic Network (PNSN) monitors ground motion and generates real-time earthquake information to emergency responders, the press and public. The project has more than 400 stations, making it the second largest seismic network in the United States. Strong-motion instrumentation, especially with real-time digital communications, requires a reliable power source. Because weather hazards often cause widespread power outages, each system must have a backup battery system with enough capacity to operate continuously for four days.

    Morningstar’s SunSavers enable many of PNSN’s power supply systems. Its EMC-1 adapter allows monitoring critical data in real-time, alerting technicians of any issues. The EMC also integrates with the Simple Network Management Protocol (SNMP) to help PNSN’s engineers plan for maintenance.

  • Powering Public Radiation and Weather-Monitoring Stations

    Application: Telecom
    Location: Nevada
    Year: 1999
    Product: SunSavers
    System size: 50 and 60-W solar panels on 24 sites
    Partners include: The Desert Research Institute

    The Desert Research Institute (DRI) of the Nevada System of Higher Education administers the Community Environment Monitoring Program (CEMP) to watch the ambient environment for radiation from past nuclear testing, ensuring the safety of nearby communities. The program encompasses 24 publically accessible radiation and weather-monitoring stations.

    Solar panels (50 and 60W) operate in conjunction with a deep-cell battery to power all CEMP station instrumentation. Morningstar solar charge controllers have kept these systems reliably running for more than two decades. 

    Residents’ direct participation in collecting data and disseminating information from these stations provides a greater sense of security. All information collected from automated sensors at these stations is posted online and updated at least hourly.
