pv magazine Focus: Manufacturers, installers, scientists discuss EMS
Installers, manufacturers, scientists and users at the Smarter E Europe event – held last week in Munich, Germany – discussed PV home storage, energy management systems (EMS), and key challenges in the implementation of Germany’s new solar provisions.
Atmoce launches retrofit-ready home battery
The Netherlands-based manufacturer is targeting older home PV arrays with its M-ELV product, which does not require replacement of solar inverters.
Swiss researchers developing control algorithm for grid-forming inverters
Researchers at ETH Zurich have patented a grid-forming inverter algorithm that stabilizes frequency while protecting devices from damage by independently controlling frequency, voltage, and current.
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.
‘Without energy storage, renewables are not serious power plants’
Chinese inverter and energy storage maker Sungrow invited 300 guests from 20 European countries to its ESS [energy storage system] Experience Day event in Munich, Germany. Discussions focused on energy storage, projects, market figures, and the energy transition. The conclusion: More storage and grid expansion are needed.
Triple Solar unveils PVT-assisted heat pump using waste heat from PV
Triple Solar BV has developed a residential photovoltaic-thermal (PVT) heat pump that uses waste heat from PV modules, eliminating the need for an outdoor unit.
German wholesalers hit by six-figure losses from new solar module scam
Suspected fraudsters are using false identities to claim they are interested in solar modules. The wholesalers typically respond by delivering the requested products, but the scammers never actually pay for their orders. These are not isolated cases, as a clear pattern has emerged.
EMPA develops biodegradable fungi battery
A team from the Swiss Federal Laboratories for Materials Science and Technology (Empa) has developed a 3D-printed battery. Fungi are used as anode and cathode with one releasing electrons during metabolism and the other able to absorb them.
Solarwatt presents new residential battery
German manufacturer Solarwatt says its new battery can be flexibly configured as an AC or DC system. It also features an emergency power function and can only be combined with Solarwatt inverters.
