What is the maximum input voltage for a 40kW 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. When the input voltage exceeds 800V, the heat generated by the loss increases sharply, causing the inverter to derate the output.
What are the input specifications of a solar inverter?
The input specifications of an inverter concern the DC power originating from the solar panels and how effectively the inverter can handle it. The maximum DC input voltage is all about the peak voltage the inverter can handle from the connected panels. The value resonates with the safety limit for the inverter.
What are the parameters of a PV inverter?
Aside from the operating voltage range, another main parameter is the start-up voltage. It is the lowest acceptable voltage that is needed for the inverter to kick on. Each inverter has a minimum input voltage value that cannot trigger the inverter to operate if the PV voltage is lower than what is listed in the specification sheet.
What is a maximum DC input voltage?
The maximum DC input voltage is to restrict the maximum open-circuit voltage of the string. It is required that the maximum open circuit voltage of the string cannot exceed the maximum DC input voltage at the lowest limit temperature.
What parameters should be taken into consideration when stringing an inverter?
In addition, the datasheet specifies the maximum voltage value of 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.
