The full-load voltage range is that the inverter can output the rated power within this voltage range. It means that, in addition to the PV module, there are some other applications of the inverter. The inverter has a maximum input current, such as 40A for 40kW. Only when the input voltage exceeds 550V, the output is likely to reach 40kW.
In the photovoltaic grid-tie inverter, there are many input voltage technical parameters: Maximum DC input voltage, MPPT operating voltage range, full-load voltage range, start-up voltage, rated input voltage and so on. These parameters have their own focus and all of them are useful. Maximum DC input voltage
The inverter has a maximum input current, such as 40A for 40kW. Only when the input voltage exceeds 550V, the output is likely to reach 40kW. When the input voltage exceeds 800V, the heat generated by the loss increases sharply, causing the inverter to derate the output.
The reason for this starts from the principle of the power inverter. For the DC-DC-BOOST circuit of the string inverter, the DC voltage needs to be boosted and stabilized to a certain value (this is called the DC bus voltage) before it can be converted to AC power. As to the 230V output, its DC bus voltage should be about 360V.
