On September 12, 2023, Sol-Ark, a leading solar and energy storage technology company, announced that it selected Enteligent's NMax Rapid Shutdown with Optimization platform for its line of direct-current (DC) module-level power electronics (MLPE) product line.
Sol-Ark's 0900-80V, powered by Enteligent, offers exceptional utility for photovoltaic (PV) solar adapters. The company recognized the market potential of 0900–80V as more than just a rapid shutdown device (RSD) and designed it to go beyond this role. By integrating the essential safety features of an RSD with additional energy optimization and data monitoring capabilities, this device provides a comprehensive solution to meet the core needs of Sol-Ark's customers.
The power optimization feature of the Sol-Ark 900-80V, powered by Enteligent, operates only when necessary, thus resulting in maximum energy efficiency, reduced internal heat generation, and increased device lifespan. When factors such as shading, snow loads, varying angles of incidence, or other conditions affect the output of PV modules, the embedded microprocessor adjusts the current output of each PV module to optimize Maximum Power Point Tracking (MPPT) both individually and across the entire string.
According to Sol-Ark's testing, the Enteligent-powered 0900-80V module delivers between 25% and 38% more power under shaded conditions than rival RSD products.
The panel-level data is transmitted using powerline communications (PLC), simplifying installation without the need for a wireless network or additional wiring. This data can be accessed through
Sol-Ark's PV Pro monitoring platform or a Windows application on a connected PC, enabling installers to verify installation integrity, assisting service personnel in troubleshooting performance issues, and allowing homeowners to monitor the performance of their solar investment.
Tom Brennan, the CEO and CTO of Sol-Ark, commented,
Initially, I was skeptical that panel-level optimization would provide any appreciable benefit over the string-level MPPT of the inverter and the PV module diodes, but once we tested Enteligent’s technology, we knew this product would be a game-changer. The increased power optimization, the addition of panel-level monitoring, and the unique longevity of this device will provide exceptional benefits for our customers.
