What is a photovoltaic inverter factory

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.

What types of inverters are used in photovoltaic 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 much power does a solar inverter produce?

Typical outputs are 5 kW for private home rooftop plants, 10 – 20 kW for commercial plants (e.g., factory or barn roofs) and 500 – 800 kW for use in PV power stations. 2. Module wiring The DC-related design concerns the wiring of the PV modules to the inverter.

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 characteristics of a PV inverter?

A large number of PV inverters is available on the market – but the devices are classified on the basis of three important characteristics: power, DC-related design, and circuit topology. 1. Power The available power output starts at two kilowatts and extends into the megawatt range.

Which type of Inverter should be used in a PV plant?

One-phase inverters are usually used in small plants, in large PV plants either a network consisting of several one-phase inverters or three-phase inverters have to be used on account of the unbalanced load of 4.6 kVA.
