BTS 5K Smart is a high-voltage battery module used to build modern BTS E5–E20 energy storage systems with a usable capacity ranging from approximately 5 to nearly 20 kWh. The module is equipped with an integrated heating system that supports battery operation in low-temperature conditions. For operation, it must be connected to the BTS 5K-BDU control unit.

BTS E5–E20 Smart energy storage systems consist of 1 to 4 high-voltage battery modules manufactured using LiFePO4 technology. They have been designed for use as residential energy storage systems. Their compact and modular design facilitates installation, operation and future system expansion.

The integrated heating system of the BTS 5K Smart modules prepares the batteries for operation at low temperatures, making the solution suitable for installation in unheated areas such as garages, utility rooms or technical rooms. The energy storage systems are compatible with selected Sofar hybrid inverters from the HYD and ME series and help increase the self-consumption of energy generated by a photovoltaic system.

Key features of the BTS E5–E20 Smart energy storage systems:

• Integrated heating system supporting battery operation at low temperatures
• Modular and integrated design for easier transport and installation
• Flexible capacity and the possibility of expanding the system from 1 to 4 BTS 5K Smart modules
• System start-up and shutdown using a single button
• Optimised battery pack operation for efficient use of stored energy
• Low battery self-consumption in sleep mode
• Safe and durable LiFePO4 cell technology
• Designed for use with compatible Sofar ME and HYD 5K–20KTL-3PH inverters

 IMPORTANT! When independently expanding the energy storage system to the BTS E20 version, an additional base must be used to install the second battery stack.  The base is available here: BTS 5K Extension – base for the Sofar E20 system
