A string inverter is a type of solar inverter used in photovoltaic (PV) systems to convert the direct current (DC) generated by solar panels into alternating current (AC) for use in homes or businesses. Key characteristics include:

1. **Configuration**: It connects multiple solar panels in series (a “string”), feeding the combined DC power to the inverter.
2. **Centralized Conversion**: It performs the DC-to-AC conversion at a single point, typically located away from the panels.
3. **Monitoring**: It provides centralized monitoring of the system’s performance, but it can be less effective if individual panels have varying levels of shading or damage.
4. **Cost-Effectiveness**: String inverters are generally less expensive than microinverters or power optimizers, making them a popular choice for installations where shading is minimal and panels are evenly matched.

String inverters are well-suited for installations where all panels receive uniform sunlight and are oriented similarly.
