Whether it’s a large-scale solar park, a small distributed energy resource site, or an energy-as-a-service business, each solar installation must dynamically manage generation and power quality to seamlessly integrate with the power grid. To achieve this, grid-connected solar installations need reliable solutions to control the point of common coupling, optimize real and reactive power, meet IEEE 1547 requirements, and mitigate common integration issues, such as varying cloud cover, nonresponsive inverter controls, and unexpected voltage excursions.SEL solar power solutions provide these essential capabilities, plus remote monitoring, event collection, and cybersecure communications. Leverage our pre-engineered control system libraries to reduce development costs and streamline deployment.
Maximize the Availability and Resilience of Solar Power Generation
For more than 40 years, independent power producers and electric utilities have trusted SEL solutions to ensure the stable, efficient, and economical operation of their systems. We build these solutions on the capabilities of the devices we manufacture, which are designed to withstand harsh operating environments, enduring temperature ranges as wide as –40° to +85°C (–40° to +185°F) and exceeding industry standards for resistance to conditions such as humidity, corrosion, shock, electric stress, and electromagnetic interference.Explore our key offerings:
- Off-the-shelf and custom-engineered solar power management solutions that control generation and battery storage, manage the point of interconnection, and provide data collection and remote site monitoring.
- Advanced solutions for feeder protection, arc-flash mitigation, controlling the point of common coupling, and meeting IEEE 1547 requirements.
- Advanced metering and power quality solutions that monitor harmonics, manage energy usage, and optimize the power factor.
