A solar inverter or pv inverter is a type of electrical converter which converts the variable direct current dc output of a photovoltaic pv solar panel into a utility frequency alternating current ac that can be fed into a commercial electrical grid or used by a local off grid electrical network.
Solar panel with power inverter.
The solar inverter is the most sophisticated part of any grid tie solar system and unfortunately it s also the part most likely to have issues.
Each string carries the dc power the solar panels produce to the string inverter where it s converted into usable ac power consumed as electricity.
Solar inverters are instrumental when it comes to solar energy harvesting and increasing the efficiency of the system.

While some solar panels and installations come with their inbuilt inverters such as the tesla powerwall 2 they still require an external solar inverter to function as a solar array fully.
This is not surprising considering inverters are usually located outside in harsh weather conditions including rain humidity and extreme heat all while generating thousands of watts of power for up to 10 hours a day.
In a grid tied system solar panels connect directly to an inverter which ties into your main household electrical panel.
String inverters solar panels are installed in rows each on a string for example if you have 25 panels you may have 5 rows of 5 panels.
It sends power into the home to run appliances and turns back the meter with excess energy.
