An off-grid application at the Eagle Ford Shale site in South Texas uses TriStar MPPT solar charge controllers to regulate battery charging to power supervisory control and data acquisition (SCADA) equipment, RTUs, and cathodic protection. The world’s largest oil and gas companies choose Morningstar products because of their reputation for reliability and strong customer support.

For more information on Morningstar’s options for solar charge controllers, check out our 30 amp, 45 amp, and 60 amp models, which have a great track record of success in a wide variety of remote power applications.


Case Study

Solar-Powered Seismic Signal Monitoring Stations

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.


Case Study

Off Grid Systems for Remote Wellheads Located Offshore Indonesia

Location: Java Sea, Indonesia
Year: 2020
Products: TriStar TS-MPPT-60 controllers
System size: 25kW for a 1.6kW continuous load with 24V, 5,500Ah battery banks
Partners include: JCE Energy

Wellhead platforms in the Java Sea play a vital role in oil and gas development, but their remote location in a harsh, hazardous environment requires a more durable and powerful means of generating electricity for critical onboard systems. JCE Energy supplies larger, more powerful solar electric systems including nickel-cadmium batteries, a monitoring and alarm system, power distribution boards, solar panels, and a Morningstar controller suitable for use in Zone 1 hazardous areas. These systems power locally installed instrumentation, telecoms equipment, navigational aids, and process equipment/motors on each platform.

Morningstar offers a variety of 60 amp charge controllers including the TriStar MPPT’s that were used in this project.


Case Study

Deterring Birds in Hazardous Locations in the Middle East

Location: Persian Gulf Coast, Middle East
Year: 2000
Products: SunSaver SS-MPPT-15L controllers
System size: 200W with 12V or 24V, 120Ah battery banks
Partners include: JCE Energy

One of the many hazards unmanned offshore installations face in daily operation is that seabirds like to use them for roosting. Not only does the waste they produce impair the efficiency of solar modules, but it can also cause serious corrosion and continual shutdowns with material failures. The challenge lies in implementing a bird deterrence system that can continually operate without access to a source of power on board. That’s why two decades ago JCE Group successfully certified the world’s first Ex Solar Power Pod (SPP) consisting of a PV module, battery, and solar controller on a steel frame. Capable of powering bird deterrent devices, they are designed to continuously operate in hazardous locations and in the presence of flammable gasses and are ATEX-approved for Zone 1 and 2 areas for use in navigation aids, alarm systems, gas detection, bird scaring, camera surveillance, ship-to-shore communications
and more. The solution’s success prompted JCE to create a dedicated renewable energy division. Today, through JCE Energy, SPPs continue to provide solutions, thriving along with Morningstar controllers in extreme environments including desert, jungle, offshore and sub-zero climates


Case Study

Creating a Sustainable Marine Experience in Greyhope Bay

Location: Aberdeen, Scotland
Year: 2020
Product: TriStar TS-MPPT-60 controller
System size: 6kW with a 48V, 900Ah battery bank
Partners include: JCE Energy

Torry Battery is a landmark artillery installation that has overlooked Aberdeen’s Greyhope Bay harbor since 1860. Today, it’s known for its spectacular panoramic views of the city and coast, as well as the largest bottlenose dolphins in the world. Conservationists wanted to renovate the Battery to create an educational marine center for the community with a zerofootprint, sustainable design. Based in the Aberdeen region, JCE Energy stepped in to provide a renewable solution to power the center plus a community space and cafe at the remote site. The system includes shipping containers equipped with rooftop solar arrays to charge batteries inside. Ultimate project goals include replacing the supplemental generator still in place with a wind turbine for a 100% green energy solution.

Street & Airfield Lighting in Indonesia

Location: Malinau Kota, Borneo, Indonesia
Products: SunLight SL-10L-12V controllers
Partners include: PT AZET

The only transportation to the town of Malinau, the administrative capital of the Regency, is by air. More than 70 Morningstar SunLight 10L to 12V, 20W DC PL lamps help light the way for planes to safely land, as well as providing essential street lighting.

Case Study

Solar Skids Power Sensors in the Chilean Desert

Location: Antofagasta, Chile
Year: 2020
Products: SunSaver SS-MPPT-15L controllers
System size: One 330W solar panel with
50Ah, 24V lithium battery per skid (54 total)
Partners include: Connexa, RELiON

Antofagasta lies between the Pacific coast and Northern Chile’s Atacama Desert. Corrosive salt in the air and harsh desert extremes combined with dangerous gasses and liquids potentially present in industrial applications create a demanding environment for power electronics. A client sought a way of remotely powering sensor systems to monitor liquids in this challenging setting. Logistics posed yet another concern: any solution had to fit in a small pickup truck and be manageable with a two-person installation. Connexa’s team constructed 54 container-loaded skid systems. Each included one solar module, a RELiON lithium battery, a Morningstar SunSaver SS-MPPT-15L charge controller, and a stainless steel enclosure. Connexa specifies SunSaver controllers because they’re approved for use in hazardous locations: Class 1, Division 2. Also, RELiON is a member of Morningstar’s Energy Storage Partner Program, which ensured a reliable, seamless solution.
