REACT 2 is FIMER’s photovoltaic energy storage system, allowing to store excess energy and optimize the energy use in residential applications.

The REACT 2 energy storage solution includes a high-voltage Li-ion battery with a long life and a storage capacity of up to 15 kWh. The modular solution can grow with the needs of any household from 4 kWh to 12 kWh (REACT2-BATT) or from 5 kWh to 15 kWh (REACT2- BATT-5.0) and significantly reduce electricity charges thanks to an achievable energy self-reliance of up to 90 percent. 

Thanks to the possibility of both AC and DC side connection, REACT 2 is the ideal solution for new systems or the retrofitting of existing ones, allowing homeowners to improve their energy self-consumption and save on their energy bills.
