PVTIME – Intersolar Europe 2025, held in the vibrant city of Munich, Germany, once again served as the global epicentre for the solar and energy storage industries. With anticipation in the air, over 110,000 attendees from around the world flocked to the event. The exhibition floor was a dazzling display of the latest technologies and products, representing the cutting edge of photovoltaic (PV) and energy storage advancements. Here we highlight some of the most notable storage and inverter offerings from the world’s leading companies.
CATL, a global leader in battery technology, has launched what it claims is the world’s first 9MWh energy storage system. Consisting of two 4.5MWh cabinets stacked vertically, it represents a novel design departure from the traditional mirror placement approach.
While the double-layer stacking concept simplifies the physical footprint, it has long been a contentious issue within the industry. Challenges with fire safety compliance, site inspections and project financing have made such designs unpopular with industry stakeholders. However, the system’s outstanding feature is its noise level of less than 65 decibels, a significant advantage for urban deployments. As the energy storage market evolves, it remains to be seen whether this innovative but controversial solution will overcome industry concerns and gain widespread acceptance.
GoodWe has launched a new range of solar-plus-storage solutions with a focus on smart, safe and flexible features.
For residential users, the ESA system (3-10 kW / 5-48 kWh) from the EcoSmart Home range stands out. Its all-in-one architecture is a compact, stylish and powerful option for homeowners seeking energy independence. The system’s built-in battery optimiser allows for easy expansion, increasing storage as needed.
In the commercial sector, GoodWe has expanded its portfolio. The ET50 hybrid inverter paired with the BAT100kWh battery cabinet and the new All-in-One ESA 125kW / 261kWh C&I system are key offerings. These commercial energy storage systems support microgrids, retrofits and backup power, while allowing MW capacity growth. They’re designed to help businesses reduce costs, improve resilience and secure long-term returns.
