RECREEN 125kW 522kWh Energy Storage Systems

Designed For Existing Commercial PV Systems

The Recreen AC-coupled ESS is specifically designed for commercial and industrial sites that already operate grid-tied solar systems.

By integrating battery storage through AC coupling architecture, the system enables businesses to add energy storage without replacing existing PV inverters.

Flexible AC-Coupled Architecture

The system connects with existing photovoltaic systems through AC coupling technology, allowing solar power generated by grid-tied inverters to charge the battery storage system efficiently.

This architecture provides:

Simplified ESS retrofit
Compatibility with existing PV systems
Reduced installation complexity
Flexible system expansion
Independent PV & ESS operation
Lower upgrade cost

Integrated 125KW Power Conversion System

The integrated PCS enables intelligent bidirectional energy conversion between the battery system and the utility grid.

The PCS supports:

Battery charging/discharging management
Grid interaction
Peak shaving
Load shifting
Backup power coordination
Energy optimization strategies

Reduce Electricity Costs Without Replacing Existing PV Systems

The AC-coupled architecture allows businesses to integrate battery storage into existing solar installations without modifying current PV inverter infrastructure.

This significantly reduces retrofit complexity while enabling:

Higher solar self-consumption
