DQ1908 ESS can be used for multiple applications
Peak load shifting
By charging and storing energy during valley hours and discharging energy during peak hours, we can reduce the electricity costs of enterprises or parks, and save electricity bills for customers.

Backup power supply
During power outages, provide uninterrupted short-term power supply to important loads to reduce economic losses caused by sudden power outages.

On demand response
When the short-term power consumption is greater than the transformer capacity, the energy storage system conducts rapid discharge to meet the load energy demand requirements.

Maximize revenue
On the electricity market trading platform, short-term electricity trading is carried out in conjunction with load forecasting.
