String Inverter

A string inverter is an inverter that converts DC power from one or more connected strings of solar modules into AC power.

What does String Inverter mean?

A string inverter is an inverter that converts DC power from one or more connected strings of solar modules into AC power.

How is a string inverter different from module-level conversion?

A string inverter aggregates DC power before conversion, so module groups can balance each other before the inverter reaches its output limit. This can reduce certain clipping patterns in mixed-orientation arrays.
