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 available?

A wide range of inverters (solar pv and storage), tailored to suit any type of system scale: residential, commercial, industrial and utility scale.

How to choose a PV inverter in Germany?

In Germany, maximum yield is achieved when the modules are aligned to the south at an angle of around 35 degrees. Next, the selection of a suitable inverter in terms of performance and technology is absolutely essential. The rated capacity of the PV array may be up to ten percent above the rated capacity of the inverter.

How many kilowatts does a solar inverter produce?

The available power output starts at two kilowatts and extends into the megawatt range. 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.

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.

What is a PV inverter without a transformer?

Whenever possible, however, inverters without transformers are used. They are a little smaller and lighter than transformer devices and operate with a higher efficiency. The tasks of a PV inverter are as varied as they are demanding: 1.
