When using more than 3 storage modules, these must be installed as a second tower. The Sofar BTS 5K Extension Kit (item 0162355) is also required.
The storage variants with and without integrated cell heating are not compatible with one another.
The BTS storage module is universally compatible with Sofar hybrid inverters as well as the All-in-One system. Up to 4 cascaded battery modules can be flexibly combined, providing a total usable capacity of 20.4 kWh. The BMS built into each unit ensures maximum flexibility during initial installation and expansion. Thanks to its flat and modular design, this visually appealing system can be easily integrated into any space.
