Powin Energy will supply its products to a portfolio of four solar + storage projects under development by Amp in Massachusetts. This portfolio represents Powin’s first projects incorporating its proprietary DC-coupled solar + storage solution. Construction is projected to start in early 2021.
Powin’s DC-coupled architecture incorporates Dynapwer DC/DC converters to charge the batteries with solar energy as it is generated without incurring the conversion losses typical in conventional AC-coupled solar + storage solutions. The flexible solution is designed to work with PV inverters from multiple vendors and ensures maximal production and utility of solar across a range of use cases, including solar shifting, low voltage harvesting, and clipping recapture — while also adding critical grid reliability benefits. Powin’s advanced control and integration software platform, StackOS, brings automated and instantaneous decision making to the projects and ensures the optimal dispatch of both the solar and storage assets. Powin’s DC-coupled solution can utilize its own optimization platform, one provisioned by a third party, or a combination of the two.
According to Powin, the portfolio consists of two solar + storage projects. The first project is 7.03 MW of solar and 3.1 MW/6.3 MWh of storage. The second project is 4.258 MW of solar and 2 MW/4.5 MWh of storage.
Geoff Brown, President of Powin, said, “Solar + storage is the future of clean energy and Amp is at the forefront of this emerging trend. We are honored to work with an industry leader like Amp, while integrating leading technology from Dynapower. We believe this partnership will demonstrate a solution that creates lasting value for Massachusetts’ energy consumers, and lead the power generation industry to a clean future.”
“Powin has been a great partner in developing these projects and this joint solution” said Jared Donald, Amp’s SVP in charge of the U.S. market. “Amp’s development portfolio of energy storage, both stand-alone and paired with solar, has increased dramatically in the last year, and it is forming a critical part of our continuing strategy around the world.”

The Powin Energy Stack 230 sounds interesting but a three hour solution I firmly believe will become outdated in two to three years. I do like the mention of solar PV compatible and 20 year useful life. As this Covid-19 shutdown commerce ‘adjustment’ period moves forward, companies will become ripe for either mergers or take overs, there will become a landscape of different sizes and shapes of energy storage companies trying to find their niche. I can see the modular expandable system becoming the most reliable technology combination to address from large homes to Small to medium Commercial operations that can be serviced in power blocks of energy storage without “over investing” in energy storage and trying to have to find a services agreement that will help pay for the system.
