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 microinverter solar panel?

Microinverters are small inverters that are mounted on each individual solar panel. Unlike string inverters, microinverters convert the DC power from each panel into AC power independently. This allows for better performance in shaded or mismatched panel situations and provides enhanced system monitoring capabilities.

Are multi-MPPT inverters suitable for a virtual central layout?

Inverters with numerous DC inputs, such as multi-MPPT devices, are not suitable for a virtual central layout since they require to be mounted close to the individual PV string. The stringing of the PV modules is typically optimized to match the ratings of the applied inverters.

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.

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 is a power electronic based inverter?

In both standalone or grid-connected PV systems, power electronic based inverter is the main component that converts the DC power to AC power, delivering in this way the power to the AC loads or electrical grid.
