The Chinese manufacturer said its 15 kW three-phase low-voltage hybrid inverter is paired with the stackable BP5000 5 kWh battery supporting up to 120 kWh. It features three MPPTs, 150% oversized PV input, and smart load management for optimised self-consumption.

High-resistivity silicon wafers offer superior efficiency potential but are highly sensitive to edge recombination and mechanical damage, limiting their commercial use compared to more robust standard wafers. Researchers from Longi and Sun Yat-sen University demonstrated that integrating in-situ edge passivation unlocks this potential, significantly boosting back-contact solar cell fill factor and efficiency.

China’s PV industry expects 238 GW to 287 GW of domestic capacity additions in 2026 as it pivots away from volume-led growth after a loss-making year driven by overcapacity and sharp price declines. The shift follows rapid expansion in 2021-25 that lifted cumulative capacity above 1.2 TW, annual additions beyond 300 GW and exports over $180 billion.

The IP66-rated Aura 5000 energy storage system features bidirectional inverter functionality and an AC output of up to 2.5 kW.

Cubenergy has launched FlexCombo 2.0, a scalable battery energy storage system for utility, commercial, and industrial applications, offering up to 16 MWh capacity with LFP batteries. Its modular design, advanced BMS, and cloud-based operations enable easy installation, seamless expansion, and efficient grid integration, according to the manufacturer.

The Chinese firm has unveiled its latest energy storage solution, the ENERpro-LFP48300, equipped with a 48V, 300 Ah lithium battery. The company boasts a lifespan of more than 9,500 cycles at a high 95% depth of discharge.

Chinese manufacturer Sungrow has introduced a new utility string inverter, a three-phase hybrid inverter for commercial and industrial applications, and a liquid-cooled energy storage system.

China-based PV equipment supplier Ideal Energy Sunflower Semiconductor has completed an AI-enabled pilot line for ultra-thin, flexible heterojunction solar cells, targeting lightweight power systems for space and near-space applications.

Researchers have used multivalent amidinium ligands to boost perovskite solar cell efficiency to 25.4%, achieving over 95% stability after 1,100 hours at 85 C. The proposed approach enables controlled low-dimensional passivation layers, offering a practical route for durable, large-area perovskite devices.

Researchers in China developed a novel two dimensional seeding agent to regulate crystallisation in a 1.80-eV wide-bandgap perovskite film. A perovskite-silicon tandem device made with the resulting optimised subcell achieved an efficiency of 31.13%, outperforming a control device.
