Energy storage inverter, applied in AC coupled energy storage system such as grid-connected energy storage and micro-grid energy storage, connects between battery bank and grid (or load), and is a device to realize two-way conversion of electric energy. The energy storage inverter can reverse the DC power of the battery into AC power to the grid or to the AC load; it can also rectify the AC power of the grid into DC power to charge the battery, so the connector's resistance to voltage, resistance to resistance and resistance to high and low temperatures need to do strict testing to meet the strict requirements of normal operation of the equipment. Jinling electronics in energy storage connectors can achieve high reliability and stability, greatly enhancing the efficiency of the use of the connector, as well as its life.
