Enershare Core Series High-Voltage Stacking Batteries Achieve CEI 0-21 Certification, Opening a New Chapter in Italy’s Energy Storage Market

Enershare, a leading provider of smart energy storage solutions, today announced that its flagship Core Series high-voltage stacking lithium batteries have successfully obtained the authoritative CEI 0-21 grid connection certification in Italy. This achievement not only affirms the safety and reliability of the Core Series, but also confirms that the product fully meets the stringent requirements of the Italian grid—offering installers and end-users a plug-and-play, fully compliant energy storage solution.

CEI 0-21: The “Technical Passport” to the Italian Market

As Italy accelerates its energy transition, regulations on the safety, stability, and power quality of grid-connected storage systems are becoming increasingly demanding. CEI 0-21, a mandatory certification, ensures that distributed generation and storage systems can operate safely and intelligently in collaboration with the national grid.
By passing this certification, the Enershare Core Series eliminates compliance concerns for customers and clears the path for broader market adoption across Italy and Europe.

Designed with flexibility, scalability, and compatibility in mind, the Core Series is engineered to meet the unique demands of the Italian and broader European energy storage market:

• Unmatched Scalability & Flexibility: With a modular stacking design, a single tower delivers robust base capacity. The system supports up to 8 towers stacked and 6 towers paralleled, scaling to a maximum capacity of 6kWh. From private villas to SMEs and large commercial projects, the Core Series delivers customized energy solutions for continuous demand. 

• Wide compatibility and seamless integration : The Core series is compatible with mainstream inverter brands in the market and has achieved stable adaptation with internationally renowned brands such as GoodWe and Solis , providing customers with more flexible system options.

• Fast Supply, Efficient Installation : Leveraging European stock, the Core series offers rapid delivery within 3-7 days , significantly shortening project cycles. Its modular structure and simplified installation process further reduce labor and time costs, helping installers improve construction efficiency.
