How you earn – clearly explained
Why would we pay you for using energy storage?
The modern grid needs flexibility to handle the ups and downs of renewable energy sources like solar and wind. Sometimes, there’s too much energy (like during a sunny afternoon), and other times, there’s too little (like during peak hours). Besst’s advanced technology helps solve this problem by allowing your battery to quickly absorb excess power or release stored energy when needed. This balancing act is critical for grid stability, and grid operators are willing to pay for it. With Besst, your system contributes to this balancing process without affecting your home’s energy needs, turning your battery into a valuable asset that earns you extra income while supporting a greener grid.
Simple financing - if you need Besst ESS 5 kWh or 10 kWh
