  • Battery inverter system
    Patent number: 11770004
    Abstract: A battery inverter system includes a plurality of battery inverter units, wherein each of the battery inverter units includes a multiphase inverter and a battery unit connected to the inverter on the DC side. The battery unit includes a plurality of individual units connected in parallel to one another and protected against overcurrent by means of rack fuses, and the battery inverter units are connected in parallel on the AC side and are configured to operate with a common drive pulse pattern. The battery inverter units are interconnected on the DC side via compensation fuses, wherein the compensation fuses are provided such that in the event of a short circuit in one of the inverters, the compensation fuses are triggered faster than the rack fuses.
