Kostar Launches Innovative Solar Storage Solutions at Intersolar Europe 2025

Global Debut! Kstar’s New Energy Storage Products Ignite Intersolar Europe 2025

On May 7, local time, the largest and most influential solar energy trade fair in the world—Intersolar Europe 2025—officially kicked off in Munich, Germany. As a provider of comprehensive solutions in the smart energy sector, Kstar showcased its innovative products and technologies, including solar, storage, and charging solutions, at booth B4.330. The company launched its BluePulse commercial and industrial energy storage solutions and the BlueSpark residential energy storage systems, designed to deliver enhanced performance, intelligence, and alignment with European market demands, thereby contributing significantly to the region’s green energy transition.

Global Premiere for Residential and Commercial Energy Storage Solutions

In response to the dual challenges of energy transition and soaring household electricity costs in Europe, Kstar unveiled the next-generation BlueSpark residential energy storage solution. With a core philosophy of “minimalist design, high safety, and intelligent ecology,” it merges aesthetics with energy technology to create a green and smart lifestyle for users.

• Easy Installation: The modular plug-and-play design eliminates the need for wiring between the inverter and battery pack, making installation quicker and more efficient. The battery module’s plug-and-play design also simplifies maintenance.
• Safe and Reliable: Featuring Tier 1 quality battery cells with higher power density and cycle life, the system reduces electricity costs for local residents and offers a 10-year warranty. It includes AFCI arc detection technology to intelligently identify arc risks with millisecond response times, ensuring user safety.
• Smart and Flexible: It supports 200% DC oversizing, catering to 100% load and battery charging simultaneously. Users can configure various operational modes such as self-consumption, time-based usage, peak shaving, battery priority, and load control, optimizing energy strategies. The system offers seamless switching to off-grid mode under 20 ms, ensuring reliable power supply and safety, while cloud monitoring and a mobile app provide real-time status visibility.

Driven by the goals of Industry 4.0 and carbon neutrality, European commercial enterprises demand higher flexibility, cost-effectiveness, safety, and intelligence in energy systems. Building on its extensive manufacturing and project experience, Kstar introduced the BluePulse commercial energy storage solution, designed to deliver smarter, safer, and more efficient energy storage systems.

• Safe and Reliable: The product uses safe, reliable, and long-lasting CATL LFP battery cells with up to 8000 cycles and a 10-year performance warranty. It features efficient thermal control and an external PCS design to minimize thermal impact.
• Outstanding Performance: With a built-in grid connection switch (10 ms switching time), it supports off-grid backup power and allows for 2x photovoltaic oversizing. Single-phase precision control prevents reverse power flow.
• Flexible Expansion: It supports connection of up to 20 units for grid applications and 6 units for off-grid applications. The innovative compact design significantly enhances space utilization, meeting diverse user needs.
• Intelligent Management: The product integrates a self-developed EMS energy management system and supports various energy strategies, including self-consumption and peak shaving. It features 24/7 cloud monitoring for real-time device status and energy efficiency data, and includes VPP virtual power plant access and OTA remote software upgrades.

Strategic Partnerships Shine at Intersolar Europe

In addition to the product launches, Kstar established several notable collaborations during the event. A strategic cooperation agreement was signed with VDH Solar, one of the largest solar product distributors in the Netherlands. This partnership signifies a deep collaboration in product, channel, and service areas, aiming to jointly explore the photovoltaic market in the Netherlands and Europe, injecting new momentum into regional clean energy development.

The event runs from May 7 to 9. We warmly invite you to visit Kstar’s booth B4.330 to experience the charm of comprehensive solar energy solutions and explore the future of energy together!
