Energy Storage

Huawei’s FusionSolar 9.0 is a new integrated solar-plus-storage platform featuring smart inverters, AI-driven management, and grid-forming capabilities to turn solar plants into active grid-support assets. It boosts efficiency, reduces costs, and enhances stability in weak grids with high renewable penetration, according to the company.

Australian researchers developed a high-resolution energy modeling framework to assess how PV and batteries can supply 24/7 electricity to heavy industries, considering cost, grid interaction, and load flexibility. They found that, while technology cost reductions help, smart grid integration and flexible industrial operations are far more effective in lowering electricity costs and enabling 100% renewable energy use.

A coalition of 18 California legislators has formally urged the California Public Utilities Commission (CPUC) to enforce regulations under “Rule 21” regarding the interconnection of customer-sited solar and energy storage systems.

The Norwegian industrial heat pump specialist said its HoegTemp system has a heat supply capacity of 0.2 MW to 5 MW and a coefficient of performance above 2 at high lifts.

NTPC has developed a standalone solar microgrid system that uses hydrogen as the storage medium to deliver 200 kW of round-the-clock power throughout the year. Designed to replace diesel gensets at off-grid Army locations, the system provides a reliable and sustainable power supply even in harsh winter conditions, where temperatures can drop to –40 C at an altitude of 4,500 meters.

South Korean solar inverter makers have jointly launched a new association of inverter manufacturers to coordinate domestic production, safeguard local expertise, and address import-driven market issues and grid stability challenges.

Offered primarily as a 10 MW unit, the new product is also available in a 5.5 MW version for customers with specific requirements.

The Chinese Ministry said it will take swift action to rein in aggressive low‑price competition that threatens to destabilize businesses and impede sustainable industry growth.

The new 12.5 kWh pack-based design supports flexible configuration up to 250 kWh per system. An optional long-duration combiner box supports 2–4 clusters, expandable to 1,000 kWh and 8 hours of storage.

In its latest monthly column for pv magazine, the International Solar Energy Society (ISES) promotes the biennial Solar World Congress (SWC), which took place in Fortaleza-Brazil in November 2025, a few days before the COP30. The SWC scientific program has traditionally been dominated by presentations on solar radiation and solar thermal applications, but this year, photovoltaics was the focus of most of the presentations. This reflects the massive adoption of PV all over the globe, which, at the current pace, will dominate the electricity mix by the end of the decade.
