Sodium-ion energy storage, already in everyday use.
In this German home, a 10-year-old storage system was replaced with a sodium-ion battery — keeping the same footprint, while increasing usable capacity.
Today, the system supports:
• winter heat pump operation
• daily household consumption
• overnight EV charging
This is one of many BIWATT sodium-ion energy storage systems already operating across Europe, showing how sodium-ion storage has become part of everyday life.
