Sofar BTS 5K battery extension kit

Discover the potential for infinite expansion with the BTS 5K expansion platform, an essential addition to your BTS energy storage system.

To maintain optimum stability and ensure unrivalled performance, we recommend stacking up to three BTS 5K batteries on top of each other. But if your ambitions go beyond this, and you're aiming for a nominal capacity of 20 kWh with four cells, it's imperative to adopt a two-unit approach. Assembling a single unit with four battery modules is not only contraindicated, it's also contrary to the spirit of efficiency we stand for. To achieve the 20 kW configuration of your dreams, simply place two modules on a BMS-equipped platform, and the other two on an additional platform.

In an age when reliability is crucial, we insist on dividing the system into two separate units when expanding to four elements. This not only enhances safety, but also ensures continuity of power supply. So, should one unit fail, the other is there to ensure an uninterrupted power supply, keeping your home always on the move.

The two-by-two arrangement is not just a recommendation, it's a requirement. It ensures that each unit has sufficient power to meet your energy needs, while preserving the safety, reliability and outstanding performance of your BTS energy storage system.

And remember, our product only includes the extension base and connectors without the BMS, because it's tailor-made to perfectly match BTS 5K batteries.
