Tesla launches three-phase Powerwall 3P
The system integrates a battery, hybrid inverter, and home energy management system into a single device. It supports the integration of additional appliances, including heat pumps via SG-Ready interfaces. A connection to Tesla’s proprietary wallbox is also planned.
Cyber threats for PV: What are distributed denial-of-service attacks and how do they work
Denial-of-service attacks overwhelm networked systems with massive traffic from compromised devices, disrupting communication and making critical services like PV system monitoring and control unavailable. They can cause operational instability, reduced energy production, and safety risks, requiring layered defenses such as filtering, redundancy, and automated mitigation to maintain system resilience.
CATL presents EV battery with 1,000 km range
Contemporary Amperex Technology Co. (CATL) has shown its latest lithium iron phosphate (LFP) battery at an auto show in Beijing. The Chinese company says it has an energy density of 205 Wh per kg, almost 8% higher than the current state of the art for such batteries.
CATL claims to have made sodium-ion batteries a commercial reality
Researchers have been keen to make the technology work as it offers a cheaper, more environmentally friendly alternative to lithium-ion products.
German start-up offers 5.2 kWh AC battery that works without inverter
Sax Power has developed a new residential battery which it describes as a game-changer in the battery technology.
Sonnen battery still running after 28,000 full charge cycles
The battery maker published test results indicating the longevity of its storage systems after extended use.
Tesla introduces solar inverter
The Tesla Solar Inverter comes in 3.8 kW and 7.6 kW versions, and features two and four maximum power point trackers.
Nextracker inks 1 GW supply deal and claims up to 12% bifacial yield gain
The 1 GW fifth phase of the Mohammed bin Rashid Al Maktoum Solar Park in Dubai will feature NX Horizon trackers with the deal announced after the manufacturer published new bifacial yield gain claims.
Plasma enables smaller, more powerful NMC-811 cathodes
Batteries could shrink even more with smaller crystals in the cathodes. Battery packs in electric vehicles and consumer goods could become smaller, while still offering high performance.
How long will the lithium supply last?
Researchers have sounded the alarm. If no serious efforts are made on second-life battery use, recycling and vehicle-to-grid applications, decarbonization efforts may hit the buffers a lot sooner than expected.
