Energy storage inverter circuit and energy storage inverter system

The utility model relates to an energy storage inverter circuit and an energy storage inverter system. A voltage conversion unit of the energy storage inverter circuit is connected with an energy storage battery and performs bidirectional voltage conversion with the energy storage battery. The bridge arm input side of the rectifier bridge unit is connected with the voltage conversion unit, and the bridge arm output side outputs first bus voltage. The input end of the voltage adjusting unit is connected with a first bus voltage, the output end outputs a second bus voltage, and the first bus voltage is boosted or reduced to obtain the second bus voltage. A bridge arm input side of the inverter bridge unit is connected with a second bus voltage, and a bridge arm output side outputs a primary voltage; the voltage output unit processes the primary voltage into an inverted output voltage. The control unit is adjusted to control boosting or voltage reduction of the voltage adjusting unit, processing of multiple volt
