Hitachi AN091802-1 allows you to power inverters from a DC supply or to connect the DC Bus of multiple inverters together to achieve energy savings. The device helps limit inrush current at power ON, avoiding unexpected UV at net side or damage to the inverter caused by ∆V=di/dt. Additionally, it uses DC chokes for each inverter to avoid interaction due to surge and/or harmonics. Furthermore, the device provides sufficient time between UV level and dead voltage of the DC/DC converter at power OFF, allowing ample time for EEPROM to store the existing data.
