World Debut! KSTAR’s New Energy Storage Products Create a Buzz at Intersolar Europe 2025

On May 7, local time, the world’s largest and most influential solar energy exhibition, Intersolar Europe 2025, grandly opened in Munich, Germany. As a provider of comprehensive solutions in the smart energy sector, KSTAR showcased its innovative products and technological achievements, including solar, storage, and charging solutions, at booth B4.330. The company also globally launched its BluePulse commercial energy storage solution and BlueSpark residential energy storage all-in-one system, designed to inject strong momentum into Europe’s green energy transition with higher performance, greater intelligence, and closer alignment with market needs.

Global Debut of Residential and Commercial Energy Storage Solutions – Building a New Smart Energy Ecosystem

In response to the dual challenges of energy transition and rising household electricity costs in Europe, KSTAR officially introduced the next-generation BlueSpark residential energy storage all-in-one system. Centered on the core concepts of “minimalist design, high safety, and intelligent ecology,” this system integrates aesthetics with energy technology to create a green, smart lifestyle for users.

• Easy Installation: With a modular plug-and-play design, the system eliminates wiring between the inverter and the battery pack, making installation quick and hassle-free. The battery module’s plug-in design further simplifies installation and maintenance.
• Safe and Reliable: Equipped with Tier 1 quality battery cells, the system offers higher power density and longer cycle life, reducing electricity costs for local residents while providing a 10-year warranty. It also features AFCI arc detection technology, which intelligently identifies arc risks and responds in milliseconds to ensure electrical safety.
• Smart and Flexible: The system supports 200% DC oversizing, accommodating 100% load and 100% battery charging simultaneously. It offers multiple operational modes such as self-consumption, time-based usage, peak shaving, battery prioritization, and load control, allowing users to optimize their energy strategies. The system can switch to off-grid mode in less than 20 milliseconds, ensuring reliable power supply and safety. Additionally, it supports cloud monitoring and mobile apps for real-time operational status updates, providing users with smarter, cleaner, and more reliable solutions.

Meeting the Demands of Industry 4.0 and Carbon Neutrality

As European industrial and commercial enterprises demand greater flexibility, cost-effectiveness, safety, and intelligence in energy systems, KSTAR leverages its extensive manufacturing and project experience to launch the BluePulse commercial energy storage solution. This solution aims to create smarter, safer, and more efficient energy storage systems for commercial clients.

• Safe and Reliable: The product utilizes safe, reliable, and long-lasting LFP battery cells from CATL, with up to 8000 cycles and a performance warranty of 10 years. It features efficient temperature control combined with external PCS design to minimize thermal effects.
• Outstanding Performance: The system includes an integrated grid-off switching device with a 10ms switching time, supporting backup power in off-grid mode. It also supports double the photovoltaic oversizing and precise single-phase control to prevent reverse power feed.
• Flexible Expansion: The system can support up to 20 units in grid-connected mode and 6 units in off-grid mode. Its compact design effectively enhances space utilization, meeting diverse user needs.
• Intelligent Management: The product integrates a self-developed EMS energy management system, supporting various energy strategies like self-consumption, peak shaving, and battery prioritization. It offers 24/7 cloud monitoring to track equipment status and energy efficiency data, and it is equipped with VPP virtual power plant access and OTA remote software upgrade capabilities.

Strategic Partnerships Shine at Intersolar Europe

During the exhibition, KSTAR not only launched new products but also established several noteworthy partnerships and industry achievements. The company signed a strategic cooperation agreement with VDH Solar, a leading distributor in the Netherlands. This collaboration signifies a deep synergy between the two parties in product, channel, and service areas, aimed at jointly expanding the photovoltaic market in the Netherlands and Europe, injecting new momentum into regional clean energy development.

From May 7 to 9, the excitement continues. We warmly welcome you to visit KSTAR’s booth B4.330 for an up-close experience of our comprehensive solar storage and charging solutions and explore the future of energy together!
