Pika Energy says its transformerless, grid-forming solar inverters are now listed to the UL-1741 standard and are shipping to customers throughout North America.
The UL-listed Pika Islanding Inverter (model X7601) is the most recent of the Maine-based manufacturer’s inverters to receive the ETL mark for UL-1741 compliance. The company notes that its X3001 inverter line has been UL listed since 2013.
According to the company, the Pika Islanding Inverter is the core component of the Pika Energy Island, a single-inverter system for solar-plus-storage applications using smart batteries. The Pika Energy Island system also includes the Pika PV Link DC solar substring optimizers.
“The UL-1741 listing for the Pika Islanding Inverter represents a significant step forward in the solar inverter industry, as there is now a third-party-certified, fully islanding, transformerless, single-inverter option that provides unrivaled simplicity for residential solar-plus-storage,” commented Pika Energy President and Co-Founder Ben Polito. “When coupled with a smart battery, the Pika Islanding Inverter enables solar-plus-storage with round-trip efficiency north of 90 percent.”
The Pika Islanding Inverter uses the company’s patented, bi-directional REbus 380VDC plug-and-play nanogrid, which uses embedded smart controls and data on the same wires as power transmission. The company says this makes the Pika Energy Island system, which requires no autotransformer, easy and quick to install.
The Pika Islanding Inverter is shipping now to customers throughout North America. The company recently announced it has been awarded funding through the U.S. Department of Energy’s SunShot Initiative to add features to the system for grid service applications, including demand response.
