Dynapower Receives Patent for Dynamic Transfer Technology

Nov. 29, 2017
The U.S. Patent and Trademark Office has issued a patent for Dynapower’s Dynamic Transfer technology, which allows for seamless transition from grid-tied to backup battery power during a grid outage.

The U.S. Patent and Trademark Office has issued Dynapower a patent for its Dynamic Transfer technology, which allows for seamless transition from grid-tied to back-up battery power during a grid outage.

The technology aims to help reduce the $120 billion that the Electric Power Research Institute estimates the U.S. faces annually in power outage costs.

The Vermont-based manufacturer of energy storage inverters and storage systems says that the technology is especially relevant to grid-tied microgrids. It allows the microgrid’s movement to battery back-up power or islanded mode without the customer experiencing any interruption. Dynamic Transfer works with use of Dynapower’s inverter.

“This technology enables our utility customers and their ratepayers to have increased energy surety and provides resiliency from energy storage systems using Dynapower energy storage inverters,” said Chip Palombini, sales manager for Dynapower’s Energy Storage Group.

The energy storage system can continue to operate on its own even if the grid is down for a long time – as is the case now in Puerto Rico, where about half the island remains without grid power following the September 20 landfall of Hurricane Maria.

Dynapower says that the transfer technology is particularly important for critical facilities, like data centers and hospitals.

Adam Knudsen, president of Dynapower, noted that at such facilities “even a short interruption in power can result in lost data, production time or food spoilage. Dynamic Transfer ensures their critical processes continue without interruption of power during a grid disturbance.”

Dynapower’s Apurva Somani, research and development lead, and Palombini are inventors of U.S. patent 9.819,190.

Inverters and energy storage systems featuring Dynamic Transfer are now operating on island nations with 100 percent renewables. The technology also is being used to help reduce electricity bills and provide critical back-up power at colleges, resorts, malls, factories, breweries, wineries, and sports stadiums.

Over the last decade, the company has deployed over 375 MWs of inverters in over 150 projects in 12 countries.
