Merit Controls Unveils PiQ41 Grid Integration Platform for Renewable Energy Generators

Secure, turnkey solution optimizes renewable asset performance

Toledo, OH, Feb. 8, 2023  Merit Controls (“Merit”), a leading provider of field-proven grid integration products and services for utility-scale renewable energy power plants, today announced the launch of its flagship PiQ41 grid integration product platform. The secure monitoring and controls platform is designed to manage utility-scale inverter-based generation resources across an optimized asset portfolio, reflecting Merit’s core values of performance, innovation, and quality. 


The PiQ41 (pronounced “peak – 41”) platform delivers industry-leading response time driven by four-quadrant, single-cycle phasor-based controls technology. Additionally, it offers an integrated solution for hybrid systems, utility-scale solar, and wind power that optimizes renewable generation and energy storage behind a common point of grid interconnection. Thanks to its robust functionality and state-of-the-art engineering, EPCs and plant operators can improve system availability to minimize downtime, mitigate risks of compliance, and optimize performance in Ancillary Services markets to maximize returns.


PiQ41 platform users benefit from direct access to a turnkey solution that controls, monitors, and manages solar photovoltaic (PV) assets, battery storage systems, and other inverter-based resources to meet current and grid requirements. The platform efficiently orchestrates the complex ecosystem of inverters and other controllable equipment necessary to meet these requirements, ensuring reliable and consistent plant operations with over 99.9% control system availability. In addition, Merit has developed the source code for this platform 100% domestically based on the industry-standard IEC 61131-3 programming environment for improved security and reliability.


“This platform is just one example of our commitment to continuously enhancing renewable power plant value,” said Tina Dornbusch, Director of Product Management at Merit. “We’re able to offer our customers a single platform of power plant controls for solar, storage, and hybrid systems that is seamlessly integrated with SCADA, highly secure network protocols, and meteorological (MET) stations for the ultimate all-in-one solution.”


The PiQ41 platform name is derived from the company’s core values: Performance, Innovation, and Quality (PiQ), as it represents Merit’s commitment to outstanding performance, innovative technologies, and high-quality service. The “41” refers to its four-quadrant, single-phasor controls technology.
