Parameters of inverter and photovoltaic panel The performance of a Solar PV Plant is totally dependent upon the key parameters of the solar PV. Some of the parameters are directly
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.
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.
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.
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.
Inverter efficiency is discussed in EME 812 (11.5. Efficiency of Inverters). Depending on the topology, most modern inverters have built-in MPP trackers to insure maximum power is extracted from the PV array. Each inverter comes with a voltage range that allows it to track the maximum power of the PV array.
