Output Voltage states the AC voltage produced by the inverter, usually 120V or 230V, depending on the applicable regional standards. The value resonates with the safety limit for the inverter. . Both the maximum voltage value and operating voltage range of an inverter are two main parameters that should be taken into account when stringing the inverter and PV array. For example, the MID_15-25KTL3-X corresponds to a rated AC output power of 15-25KW. It converts the variable direct current (DC) output of a photovoltaic (PV) solar panel into alternating current (AC). Inverters generally have an input voltage of 12V, 24V, or 48V.
