6 FAQs about [Various parameters of photovoltaic 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 parameters should be considered when stringing an inverter and PV array?

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.

How do I choose a PV inverter?

Each inverter comes with a voltage range that allows it to track the maximum power of the PV array. 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).

How to match a solar inverter with a PV plant?

To couple a solar inverter with a PV plant, ensure that certain parameters match between them. After designing the photovoltaic string, calculate the maximum open-circuit voltage (Voc,MAX) on the DC side (according to the IEC standard).

What are the main categories of inverters used in PV applications?

Inverters used in photovoltaic applications are historically divided into two main categories: Standalone inverters are for the applications where the PV plant is not connected to the main energy distribution network.

How to choose a PV array maximum voltage?

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.
