The Nexis solution combines a flexibly configurable hybrid inverter with a modular high-voltage battery offering up to 14 kW charging capacity per stack. The inverter delivers 8–20 kW AC power, supports up to 200% DC oversizing, and features IP65-rated design with integrated backup power.

The K2 MultiRail High mounting system is a one-piece elevated solution with a height of 100 mm tailored to improve rear ventilation on metal roofs. K2 Systems says greater distance between modules and metal roof surface improves airflow and lowers module temperature, which can translate to higher annual energy yield.

An international research team, including scientists from the University of Queensland, boosted triple-junction solar cell performance by enhancing perovskite crystal growth, increasing middle-cell light absorption, and adding reflective nanoparticles.

A random malware variant affected about 800 remote monitoring devices at ground-mounted PV plants in Japan in May 2024. Tokyo-based cybersecurity firm Girasol Energy has told pv magazine what happened and how PV asset owners can protect themselves against such incidents.

Scientists from three leading Australian research organisations have developed the first proof-of-concept quantum battery, demonstrating the potential for rapid, scalable charging and energy storage based on principles of ollective effects.

Researchers have developed a smart water-spray cooling system for PV panels that activates only when temperatures exceed a set threshold, boosting efficiency while minimising water use in arid conditions. The system raised power output and reduced module temperatures, offering similar efficiency to continuous cooling but with far lower water consumption, pump operation, and costs.

Researchers from the Australian National University and Longi used photoluminescence imaging to analyse dopant distributions in RCz-grown silicon wafers doped with antimony, phosphorus, and gallium, finding highly uniform radial concentration profiles suitable for high-efficiency solar cells. The study also found that antimony-doped wafers provide more stable axial doping along the ingot, highlighting their potential for next-generation PV manufacturing.

Australian battery and electric vehicle tech company 3ME Technology has teamed with United States-based South 8 Technologies to develop lithium-ion battery solutions utilising liquefied gas electrolyte-enabled cells for extreme cold weather and Arctic applications.

New South Wales-based thermal energy storage system developer MGA Thermal intends to rapidly scale its manufacturing capacity and commercial capability after securing $17 million in new funding.

VicGrid is inviting expressions of interest from developers to partner in the delivery of at least three new synchronous condensers at or near the Hazelwood terminal station in the Latrobe Valley.
