JFSC500 Storage Reversible Rectifier
| Application: |
| This product is applied to compose intelligent grid. It can be used in the power-storage link and balance electric difference caused by day/night and seasons to guarantee grid safety. It’s an important premise for application of renewable energy source and an efficent method for management of grid interaction. It’s the indispensable baisc link for intelligent grid because of regulating and controling power source. |
| Features: |
|
1. Double inversion, charge/discharge
2. Design for grid, and can accept regulation of intelligent grid
3. Floating charge, constant current charge,constant voltage charge, constant power charge,etc.
4. AH discharge, voltage-limited discharge,constant power discharge, constant current discharge,etc.
5. Islanding effect test
6. Islanding system inversion
7. Full isolation between battery and grid
8. Battery electric leakage test
9. Perfect display and communication centralized control function
10. Low voltage ride through and reactive compensation |
| Functions: |
| Three working modes:gird-connection, islanding system and hybrid systems.It takes double inversion as basic feature. It has the function of unit power factor grid connection charge/discharge,independent inversion, acceptance of grid regulation and 、active and reactive power adjustment, dynamic/static grid support and reactive power compensation.In different working modes,it can supply peak load shifting, emergency independent inversion. | |
