Battery Energy Storage System (BESS) is a rechargeable battery system. Its purpose is to help stabilize energy grids. It stores excess energy from solar and wind farms during off-peak hours. BESS then feeds this stored energy back to the grid during peak hours. This ensures a continuous, reliable power supply. A BESS comprises several main components. Together they store and manage energy flow efficiently. Leading brands like Sungrow offer integrated Sungrow BESS solutions utilizing the latest battery technologies.
Sungrow BESS System: Main Components Overview
Sungrow is a reputed renewable energy solutions provider. Sungrow BESS systems feature three main components:
1. PV Inverters
A solar inverter transforms the power generated by solar panels into a form of electricity that can be readily utilized. Sungrow uses highly efficient string inverters. Their photovoltaic inverters are available in a variety of sizes, starting at 450W and going all the way up to 8.8 MW, with impressive efficiency rates above 99%. They’re designed to handle solar energy conversion for projects of any size you might have in mind. This ensures optimal charging and discharging performance.
2. Power Conversion System (PCS)
This essential setup takes the direct current (DC) from traditional or renewable energy sources and transforms it into alternating current (AC) for distribution purposes. Sungrow’s power conversion system is designed for high efficiency and reliability. Ranging from 50kW to 8MW, Sungrow’s PCS meets the majority of requirements. It features effective forced air cooling, ensuring no derating up to 55°C, and a wide DC voltage operation window for full power operation. The system’s modular design facilitates easy maintenance, and its IP65 protection degree makes it suitable for outdoor installations. Sungrow’s PCS is compatible with high-voltage battery systems, offering low system costs and integrated battery charge & discharge management with a black start function.
3. Batteries
Sungrow BESS uses LFP battery modules in BESS systems. In the market, various battery chemistries can be used for energy storage in BESS applications. So, why did Sungrow choose LFP? Let’s compare the common types of batteries to get the proof:
4. LiFePO4 Batteries (LFP)
Often considered the best chemistry for industrial use. It’s the core technology in Sungrow’s PowerTitan 2.0. LFP offers high thermal stability with no risk of fire or explosion, even during abusive conditions. It can endure thousands of charge/discharge cycles with minimal capacity loss. It maintains high capacity even after thousands of cycles.
5. Lithium-ion Batteries
In BESS applications, lithium-ion batteries provide a decent alternative but require additional safety circuits and ventilation. Continuous monitoring is also needed as overcharging can cause overheating. While offering competitive performance, reliability and degradation over time remain a concern. When it comes to these factors, they are considered medium.
6. Lead-acid Batteries
These batteries are an affordable option. They are still used in some off-grid areas and BESS systems but have notable drawbacks. Low energy density means more battery racks are needed. The condition must be monitored via periodic water top-ups to maximize a lifetime under 2-3 years only. These batteries are also more prone to damage from fully discharging. Overall, they are considered the worst option for BESS systems.
In summary, LFP batteries provide the best combination of application safety, long cycle life, minimal maintenance, and storage capacity for large BESS projects. LFP batteries provide superior performance even in hot climates. They overheat less. They also boast a long lifespan with thousands of charge-discharge cycles. This translates to a long lifetime, lower maintenance costs, and high reliability in terms of energy storage management.
7. Energy Management System
A centralized monitoring and control system from Sungrow intelligently oversees the flow of energy into and out of the battery bank. It controls the inverters and ensures batteries charge during sun/wind and discharge during peak demand periods only. Advanced Sungrow BESS and Sungrow power supply algorithms maximize the utilization of lower-cost renewable energy. Sensors track battery health to protect long-term performance and prevent overcharging.
8. iSolarcloud
Sungrow’s iSolarCloud is an advanced monitoring platform tailored for managing the operation and maintenance of solar and energy storage systems. It enables centralized management to lower operational and maintenance costs, featuring customizable performance views for thorough oversight of the entire plant. Accessible through both a web portal and a mobile app, it provides real-time fault analysis and rapid troubleshooting. With hierarchical access controls and redundant data storage, it ensures the security and reliability of your investment.
