At present, there are some pain points in the application of energy storage industry, such as safety concerns, profit difficulties, engineering load, layout constraints. ANE innovative distributed energy storage solution has thoroughly solved the above pain points.
Cascade Battery Utilization Solution
- One channel connected to one battery cluster, One channel connected to two battery clusters, One channel connected to three battery clusters, direct matching of cascade battery packs by NESI-30K wide voltage Group Strings PCS (DC voltage range 200-900V), without unpacking battery pack and series-parallel connection of battery packs.
- Centralized control of multiple 30kW with two-stage topology PCS AC side in parallel.
This scheme greatly reduces the difficulty of power battery cascade utilization and has excellent economy performance.
Energy storage and backup UPS solution
- Energy storage backup UPS usually cuts the peak and fills the valley, and supplies power to the equipment replacing the online UPS protection when the city power is abnormal.
- Reduces lead-acid battery usage in online UPS
