Product information "SOFAR CBS5000 40 kWh Energy Storage + 20 kW 3-Phase Inverter + EMS Pro HV"
The energy storage system with the SOFAR HYD20K-T1 three-phase hybrid inverter and a battery storage based on the SOFAR CBS5000 system with a capacity of 40.96 kWh is a modern solution for companies, commercial buildings and industry. The kit allows efficient management of energy from a photovoltaic installation, increases self-consumption and reduces the cost of buying energy from the grid. By storing surplus energy, the user gains greater energy independence and security of supply.

The SOFAR HYD20K-T1 + CBS5000 40.96 kWh kit includes:

The iONTEC Connect EMS energy management system combines the PV installation, energy storage and loads into one intelligent system. It automatically decides when to charge and discharge the battery, uses dynamic RCE energy prices, limits grid export and controls selected loads. As a result, it increases self-consumption and lowers energy costs – without manually changing inverter settings.

If you would like to expand the kit or prepare a custom configuration, please contact your sales representative.

Energy storage and increased self-consumption are among the most effective ways to improve a company's energy efficiency. The kit based on the SOFAR HYD20K-T1 and the CBS5000 40.96 kWh battery system stores energy produced by the PV installation and makes it available when it is needed most. The solution works well wherever reducing energy costs, increasing independence from the grid and improving the energy security of the site are important.


The SOFAR CBS5000 battery system uses safe LiFePO₄ (LFP) technology, which ensures high durability, stable operation and a long service life. The kit, consisting of eight BMU modules and a BCU control unit, offers a total capacity of 40.96 kWh. The modular design allows the system to be expanded as the site's energy demand grows.

The SOFAR HYD20K-T1 hybrid inverter is a modern device designed to work with high-voltage energy storage systems. It enables intelligent management of energy flow between the PV installation, the energy storage, loads and the grid. It supports self-consumption optimisation, energy management and integration with monitoring and EMS systems. Thanks to its high efficiency and reliability, it is ideal for commercial and industrial applications.
