Without an inverter, your solar panels produce electricity that your home can't actually use. That's because solar cells generate DC power, while most homes and appliances run on AC.
Why do solar cells need an inverter?
The earliest known use of an inverter can be traced back to the early 20th century. Inverters were then used primarily in industrial settings to convert direct current (DC) power from batteries and generators to alternating current (AC) for use in machinery.
What is a solar inverter?
A solar inverter is a key component in a solar energy system. This little box is responsible for converting the direct current (DC) output of the solar panels into alternating current (AC) electricity. It is the AC power that runs our homes and businesses, or is fed into a utility grid.
How does a solar inverter work?
A solar inverter converts the current through a process of electronic switching and voltage transformation. How solar inverter works can be broken down into the following steps: Solar panels convert sunlight into DC power, which is sent to an inverter. The inverter converts the energy it has received into a low-voltage DC power.
What makes a good solar inverter?
Inverters with a higher efficiency rating convert more power to usable electricity and waste less energy in a form of heat. Most solar inverters have an average efficiency rating of around 96 to 98 percent. Another useful characteristic you should know about is the Maximum Power Point Tracking (MPPT).
What are the components of a solar inverter?
As one of the most important pieces of equipment in your solar system, an inverter is composed of these important components. Power electronic switch: The electronic switch, also known as an inverter bridge, is responsible for switching the direct current from solar panels into alternating current.
What are the different types of solar inverters?
There are two main types of solar inverters: string inverters and microinverters. String inverters are typically used in large-scale solar systems where multiple solar panels are connected in series (or “strings”) and the DC electricity is passed through a single inverter for conversion.
