What is a central inverter?
The inputs to central inverters are most often combined dc circuits from many (or all) strings in the array that feed a small number of integrated MPPTs. The likelihood of encountering a central inverter on a project increases with project size and age. Utility-scale projects above ~10 MW are the most common application today.
How much power does a central inverter produce?
They are rated from around 600 kW to 4000 kW. Central inverters typically rely on single-stage power conversion, and most inverter designs are transformer-based or isolated. In the DC-AC stage, variable DC is converted to grid-compatible AC power. Two-level or three-level NPC1 / NPC2 / ANPC topologies are preferred in this stage.
What is a Sungrow central inverter?
Sungrow central inverters come in power outputs ranging from 500 kW to 6.8 MW, suitable for utility-scale applications such as industrial facilities and commercial buildings.
What are the different types of PV inverters?
There are three primary tiers of PV inverters: microinverters, string inverters, and central inverters. Since microinverters are not rated for utility-scale voltages, we will largely ignore them in this article. String inverters convert DC power from “strings” of PV modules to AC and are designed to be modular and scalable.
What is an ABB central inverter?
ABB central inverters are ideal for large photovoltaic power plants and medium sized power plants installed in commercial or industrial buildings. High efficiency, proven components, compact and modular design and a host of life cycle services ensures ABB central inverters provide a rapid return on investment.
Will my project have a central inverter?
The likelihood of encountering a central inverter on a project increases with project size and age. Utility-scale projects above ~10 MW are the most common application today. Large C&I and smaller utility-scale projects from just a few years ago are likely to have central inverters as well, for reasons we’ll touch on in the next section.
