C&I Energy Storage System


PowerCombo-20C2H500K is a battery energy storage system with nominal power of 500kW and capacity of 1,104kWh. The system is integrated in 20ft standard containers, which is ideal for most of 0.5 C&I application as the system is easy for deployment and maintenance. With all-in-one design, 8 sets of S138 battery string, PCS, transformers, fire fighting system, environmental control system and BMS are integrated inside. By deployment, it is widely applied in smoothing renewal energy output, frequency modulation and peak valley arbitrage.

C&I Energy Storage System

Capacity Compensation

In the case that the user-side load is higher than the capacity coming from the grid, PowerCombo BESS employs a dispatch strategy to automatically compensate capacity to the power distribution system and improve the voltage quality on the user side.

C&I Energy Storage System

Load Shifting

Store energy in off-peak hours and discharge it during peak hours, to reduce electricity costs by partially replacing expensive peak electricity.

C&I Energy Storage System

Sizable Income

Establish good interactions with the power grid partners by getting involved in demand response programs. Contribute to reduce peak load and get incentives from the grid.

C&I Energy Storage System

Smooth Output Curve

Ensure that renewable energy can be easily dispatched. PowerCombo BESS will discharge energy when in need, to shave load spikes and reduce the use of grid power during peak hours.

C&I Energy Storage System

Better Utilization of Renewable Electricity Generation

Fully leverage the flexible energy storage system to increase the consumption of electricity generated from renewable energy sources and reduce the curtailment of wind and solar power,to alleviate the stress on the grid during peak and valley hours.

C&I Energy Storage System

Backup Power Supply

PowerCombo BESS can be used as a backup power supply in the event of a sudden power outage. The discharge mode will be instantly switched on to offer support to critical loads and safeguard the normal operation of critical loads.
