Each varies with features and costs.
Solar panel and converter.
Solar inverters are devices that convert the electricity from the solar panels which is generally in direct current into alternating current.
Sometimes mistakenly called a converter solar panel inverters deal less with voltage level and more with current type switching power from dc to alternating current ac what most home appliances use to function.
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.
It sends power into the home to run appliances and turns back the meter with excess energy.
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.
When your panels produce energy it all gets sent to a single inverter which is usually located on the side of your home in a garage or in your basement.
Multiple strings are connected to one string inverter.
In a grid tied system solar panels connect directly to an inverter which ties into your main household electrical panel.
Without a solar inverter energy harnessed by solar panels can t easily be put to use.
String inverters microinverters and optimizers.
Most appliances lighting and household electronics use the alternating current hence the conversion need.
