Enphase microinverter-based solar systems 45 to 70 times more reliable

PETALUMA, USA: Enphase Energy released field data demonstrating the reliability of its microinverter technology. The data, collected separately and independently by Westinghouse Solar and SunEdison over a two-year period from 2008-2010, show the reliability of microinverters is 45 to 70 times greater than traditional central inverters. This level of field-proven reliability allows installers and system owners to benefit from the exceptional system uptime that the Enphase Microinverter System provides.

“Reliability and quality are core to what we do at Enphase. We’ve incorporated the experience of having sold and supported more than 750,000 units into our manufacturing process and new product designs,” said Paul Nahi, CEO of Enphase Energy. “This empirical data from Westinghouse and SunEdison illustrates the reliability of our Microinverter System and the value that our estimated 99.8 percent uptime delivers to our customers.”

Enphase follows an end-to-end process, from development through manufacture, to ensure the reliability and durability of its microinverters. Each microinverter uses carefully selected components and is designed so individual components are stressed well within specification. Finally, units undergo a multi-stage testing process at the factory to minimize material or workmanship defects throughout the manufacturing process.

“Our leading AC solar solutions leverage the reliability of Enphase microinverters,” said Barry Cinnamon, CEO of Westinghouse Solar. “Our AC modules, with built-in Enphase microinverters, and integrated racking, wiring and grounding reduce field assembled components by 80 percent and labor by 50 percent. Field data has shown that these AC systems are more reliable, provide a higher ROI to the system owner and reduce on-going system maintenance costs.”
