Solar-plus-storage for extreme low temperatures
Scientists in the United States have created a testing platform for energy harvesting in solar-plus-storage systems under extreme temperatures ranging from -180 C to 300 C.
Power electronics for customized battery energy storage
Startup p&e power&energy is offering multilevel inverter technology to manufacturers and integrators of battery energy storage systems (BESS). Interconnecting individual cells enables cost savings and the service life and efficiency of the systems, which can be individually configured for each application, can be increased.
Heat pump control strategy for energy communities
Researchers have utilized measured data from a small energy community on a Finnish university campus to simulate its operation under various control strategies. The first control strategy prioritizes the use of heat pumps, while the second prioritizes price. Total costs were reduced by up to 25% with the second option.
France’s Imeon launches AI-powered home solar-plus-storage system
Neo learns and adapts to user consumption habits, ensuring optimal use of rooftop solar energy and improving battery life.
Swedish grid operators reluctant to integrate batteries
A report from Svensk Solenergi says connection to the electricity grid is a significant obstacle to the expansion of battery storage technology in Sweden, with grid operators often hesitant to connect large-scale projects.
Sprsun unveils air-source heat pump for swimming pools
The Chinese manufacturer said its new heat pump system has a heating capacity of 6.5 kW to 17 kW and a coefficient of performance ranging from 4.8 to 5.23 at 15 C.
Tesvolt presents new C&I battery storage system with 15 year performance guarantee
With two cycles per day, the Forton can be loaded without voiding its 15-year performance guarantee. That opens the possibility of trading on the electricity market, enabling companies to recoup their investment more quickly.
German home battery sales collapse but larger systems on the rise
German energy storage sales are shrinking, especially home systems, but commercial and industrial (C&I) and utility-scale numbers are rising and the Federal Association of Energy Storage Systems (BVES) wants faster permitting and better regulation.
