6 FAQs about [Important 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.

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 does a PV inverter do?

The inverter is the heart of every PV plant; it converts direct current of the PV modules into grid-compliant alternating current and feeds this into the public grid. At the same time, it controls and monitors the entire plant.

How to pair a solar inverter with a PV plant?

In order to couple a solar inverter with a PV plant, it’s important to check that a few parameters match among them. Once the photovoltaic string is designed, it’s possible to calculate the maximum open-circuit voltage (Voc,MAX) on the DC side (according to the IEC standard).

What is the power rating of a solar inverter?

A solar inverter's 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. It's important that Maximum PV input power is never exceeded by the power output from the combined panels, or else the inverter runs inefficiently.
