HVAC System:
The environmental control system inside the ESS adopts precision heating, ventilation and air conditioning designed to ensure ideal internal temperature whether discharging, charging or on standby.
1. Cooling - cooling starts when the containers internal temperature exceeds the cooling set point, and it stops when the temperature drops below the cooling set point.
2. Heating - heating starts when the containers internal temperature is lower than the heating set point, and it stops when the temperature rises above the heating set point.
3. Dehumidification - dehumidification starts when the containers internal humidity exceeds the dehumidification set point, and it stops when the humidity drops below the dehumidification set point.
FIRE Suppression System:
The fire suppression system is designed according to the container size, and the fire extinguishing gas is discharged from the extinguishing gas cylinders to the main pipeline and then to branch pipelines and sprayed from nozzles. The system includes fire detectors, audible and visual alarm, emergency start/stop button, gas release indicator, gas extinguishing controller, etc.

Applications
In the case that the load is higher than the capacity coming from the grid, PowerCombo BESS conducts a dispatch strategy automatically to compensate capacity to the power distribution system and improve the voltage quality behind the meter.
Store energy in off-peak hours and discharge during peak hours, to reduce electricity bill by partially replacing expensive peak-price while maintaining sufficient electricity supply.
Sunpal BESS is the resource to deliver real-time and precise responses to deviations in the grid frequency, such as FCR&FRR. supporting balancing service providers to adjust active power output/consumption in order to minimize the imbalance between demand and generation on the system
4. Renewables Power Arbitrage：
Sunpal BESS allows the excess power fromrenewables to be stored at high production times /low demand then discharged at low production times/peak demand, which will bring the benefits of avoiding high tariff electricity costs and creating a flat charging profile
6. Backup Power Supply:
Sunpal 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.
