When the power grid is unstable, the device that provides stable power to the back end of the UPS is different from the application of the energy storage system. The back end of the UPS mainly outputs to fixed and important loads, and the energy storage system can Two-way charging and discharging of the power grid, UPS can only be used in one direction, and in the online uninterruptible power system, regardless of whether the power grid is normal or not, the power supply will be provided to the load through the UPS, so when the power grid is abnormally interrupted, there is almost no switching time (< ;30ms).

 

      FlexLi-V is a new generation product developed by Tianyu Industry. It can be flexibly applied to ±256VDC and 512Vdc uninterruptible power system (UPS). The number of combined cabinets can reach 10 cabinets. It also integrates a self-developed high-performance battery management system (BMS), which has various protection functions such as system overvoltage, system undervoltage, cell overvoltage, cell undervoltage, charging overcurrent, discharging overcurrent, insulation fault protection, etc. At the same time, it has RS485, CAN, and dry contacts to realize remote monitoring and reduce daily maintenance investment.
