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.
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. PV designers should choose the PV array maximum voltage in order not to exceed the maximum input voltage of the inverter.
PV designers should choose the PV array maximum voltage in order not to exceed the maximum input voltage of the inverter. At the same time, PV array voltage should operate within the input voltage range on the inverter to ensure that the inverter functions properly.
The inverter power rating signifies the total wattage of loads it can support. The power generated from the string of solar panels which is given to the inverter is called Maximum PV input power. Maximum PV input power must never be exceeded by the power output from the combined panels. Else the inverter runs inefficiently.
It is recommended to match that range when selecting the inverter and the PV array parameters. Inverter MPPT is discussed in EME 812 (11.3 DC/DC Conversion). In most applications, the solar inverters are exposed to ambient conditions such as solar radiation, temperature, and humidity.
As power is processed and converted from one shape to another, the solar inverters are expected to perform these tasks with the highest possible efficiency. This is because we wish to deliver maximum PV generated power to the load or the grid. Typical efficiencies are in the range of more than 95% at rated conditions specified in the datasheet.
