FAQ
Frequently asked questions about the SOFAR BTS Battery Storage
How many modules can I combine?
Up to 6 BTS modules can be combined per hybrid inverter, resulting in a maximum storage capacity of 30 kWh.
Are the BTS batteries safe?
Yes, the BTS batteries use lithium iron phosphate (LFP) cells, which are considered particularly safe. In addition, a multi-stage battery management system provides protection.
Can I start with one module and expand later?
Yes, that is the big advantage of the modular design. You can start with one 5 kWh module and add more modules at any time.
