String inverter photovoltaic system diagram

What is a solar string inverter?

Solar string inverters are used to convert the DC power output from a string of solar panels to a usable AC power. String inverters are commonly used in residential and commercial installations. Recent improvements in semiconductor technology is allowing for string inverters with high power density (from 10s of kW to 100s of kW).

What is a string power inverter?

These inverters can accommodate several panels depending on wattage rating. String power inverters are different from alternative solar inverters by their unique structure, which mainly involves a string of interlinked panels. Your inverter may appear to be a simple component housed outside your house but it comprises numerous components.

Can string inverter solar panels be wired together?

As discussed above, string inverter solar panel arrays can be wired together in series or parallel — or a hybrid of both. All PV modules that capture sunlight and convert it into electricity using the photovoltaic effect produce direct current (DC) power.

How does a string inverter work?

A string inverter permits you to utilize solar energy in powering your electrical components by supplying sufficient AC power. Once the sunlight strikes the myriad of solar panels on your roof, it is instantaneously transformed into DC power by the respective photovoltaic cells.

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.

How to connect a string solar inverter to a power supply board?

To connect your string solar inverter to your electronic device, grid, or power supply board, you must first unpeel the protective wrap. After this, you may proceed to plug in the terminals of the power circulation board. However, you must be cautious of the board’s input configuration.
