6 FAQs about [Photovoltaic string inverter power transmission solution]

Where are string inverters located in a PV plant?

There are two ways to place the string inverters in the overall PV plant layout: Either decentralized or distributed in the PV field at the end of each string, or alternatively at one central location within the PV plant (typically adjacent to the transformer station). The inverters are mounted on a rack.

What ICs are available for a string or central solar inverter system?

Discover ST's solutions and ICs for your string or central solar inverter system design, including SiC MOSFETs, IGBTs, power modules, microcontrollers and connectivity solutions.

What is a virtual central PV string inverter?

Virtual Central approach of PV string inverters – a cost benefit Compared to the traditional mounting arrangement where the inverter is fixed decentral at the end of each PV string the so called virtual central offers many benefits.

How do string inverters work?

String inverters typically rely on two-stage power conversion. First, the DC-DC stage converts variable DC voltage into a suitable or fixed voltage required by the DC-AC inverter stage. At the same time, it ensures maximum power, which has been extracted from the PV string via MPPT (Maximum Power Point Tracking) technique.

What are the advantages of centrally installed PV string inverters?

The obvious advantages of centrally installed PV string inverters are higher flexibility in PV system design, suitability for larger PV modules, easier access to the inverters for maintenance and operation purposes, faster installation and commissioning and, most of all, superior yield and an improved performance ratio.

What is a PV inverter?

As clearly pointed out, the PV inverter stands for the most critical part of the entire PV system. Research efforts are now concerned with the enhancement of inverter life span and reliability. Improving the power efficiency target is already an open research topic, as well as power quality.
