BYD unveils 14.5 MWh storage system, world’s largest yet
China’s EV giant has unveiled the 14.5 MWh DC “Haohan” single-unit DC block with record-breaking capacity to challenge next-generation energy storage market.
AlphaESS releases liquid-cooled ESS for commercial, industrial use
The Chinese storage manufacturer said its new energy storage system has a capacity of 261 kWh per cabinet. It can be expanded up to 50 units in parallel, scaling to multi-MWh projects.
Making the business case for solar-plus-storage with heat-pumps in Japan
A Japanese research team has evaluated the affordability of photovoltaic-battery systems featuring heat-pump water heaters and air conditioning units across nine regions of Japan. They analyzed three price policies and two loan types, identifiying a tradeoff between net demand and cost according to the capacity of the solar-plus-storage system.
French solar developer Everwatt goes bankrupt
EverWatt, a French solar developer, entered receivership this summer after investors withdrew support, leading to layoffs and the sale of its assets while the company seeks buyers for regional solar projects.
PV-powered thermal distillation device with self-cleaning, cooling
Scientists in Hungary have built a prototype of a thermal distillation device, supported by PV power. The PV panels use an IoT component that self-cleans when dust is detected and cools itself when the temperatures are too high. The system achieved a daily freshwater yield of 6.1 L/m2⋅day.
SolarEdge unveils all-in-one residential inverter and clickable modular battery system
The stackable battery ranges 4.9 kWh to 19.6 kWh per unit while the inverter is available in ranges from 3.8 kW to 13 kW. The company also introduced a meter socket adapter to avoid triggering costly main panel upgrades.
Hands-on with the Bluetti Apex 300 portable power station
A hands-on with the Apex 300 reveals it has unique strengths for those looking for portable power in a design that is made to expand through accessories.
Floating PV system with ring-like floater geometry
Scientists in China have investigated the hydrodynamic performance of a novel modular floating photovoltaic system. They did so using a novel hybrid approach, which integrates viscous-flow effects from computational fluid dynamics into a potential-flow solver. They analyzed the new system with varying numbers of panels, either in a single chain or a parallel configuration.
Chinese Academy of Sciences developing thermoacoustic heat pump for industrial applications
The researchers developed a heat-driven thermoacoustic heat pump that can purportedly achieve a temperature lift of 125 C. It uses a thermoacoustic heat pump to stably release the heat from the engine unit. The system also includes a thermoacoustic engine unit and acoustic resonators.
Enphase introduces 97.5%-efficient microinverter based on gallium nitride tech
The inverter is designed for three-phase grid configurations without using external transformers. It contains gallium nitride technology, a first for Enphase’s microinverters.
