Frequently Asked Questions


What is an Energy Management System (EMS)?

A researcher in distributed energy once said, “Good solutions stem from top-level design; good systems arise from EMS.” This clearly underscores the importance of EMS in energy storage systems.
The Energy Management System (EMS) is designed to aggregate information from various subsystems within the energy storage system, provide comprehensive oversight of the entire system’s operational status, and facilitate data-driven decision-making to ensure the system operates safely. The EMS uploads data to the cloud, providing operators’ back-end management personnel with powerful operational tools. At the same time, the EMS also handles direct interactions with users. Users’ operations and maintenance staff can use the EMS to monitor the energy storage system’s operational status in real time, enabling them to carry out effective supervision and control.

What is the after-sales response time?

SAV has localized service centers in every region, offering real-time after-sales support and providing solutions within 24 hours when you encounter any malfunctions.

How is the revenue from peak-shaving and valley-filling calculated?

Each of SAV’s power stations is equipped with metering meters approved by the grid company. Real-time data is collected via remote meter-reading devices, and a monthly electricity bill detailing your revenue is sent to you, ensuring that you receive accurate information on your monthly electricity earnings.

What is SAV’s O&M frequency?

The project has dedicated operations and maintenance personnel who are online 24 hours a day. Colleagues will arrange for operations and maintenance staff to conduct quarterly, semi-annual, and annual power station inspections, and ensure standardized operations and maintenance according to requirements. For power stations located in harsh operating environments, monthly operations and maintenance will be carried out.
