Lithium battery Sofar Solar BTS + BDU- 5kWh
Smart residential energy storage system, 5–40 kWh
The battery capacity can be easily expanded thanks to the modular and stackable design of the system (a maximum of 4 batteries per BDU management system). In combination with quick-connect cables, installation is both quick and user-friendly. Up to two systems can be connected in parallel, representing an energy storage capacity of 40 kWh.
BTS series is compatible with battery inverter series HYD 5K-20KTL from Sofar Solar as well as the inverter WKS opti-C.
The BDU + Base distribution unit is required to ensure optimal battery use.
- 1 BDU for 4 batteries
