How Do Solar Inverters Work?

PUBLISHED: Sep 11, 2024

In the heart of the Lone Star State, solar inverters are transforming the way we harness energy. These unassuming but revolutionary devices play a pivotal role in the solar energy ecosystem, converting the sun's abundant DC power into usable AC power. 

 

If you've ever wondered about solar panels and how they power your world, this blog post is tailor-made for you. We'll unravel the essential functions of these energy transformers and embark on an enlightening comparison between micro inverters and string inverters.

 

The goal? To help you make informed choices and become a solar-savvy Texan homeowner.


What Does a Solar Inverter Do?

 

Imagine solar panels are diligent workers as they absorb sunlight and convert it into direct current (DC) power. But here's the catch: Most of our appliances and gadgets crave alternating current (AC) power to function. 

 

This is where the solar inverter steps in. Its primary role is to convert the accumulated DC power from your solar panels into AC power, ready to light up your life. Without solar inverters, the energy harvested by your panels would remain locked in a different energy dialect, unable to power your home.

 

Micro Inverters vs. String Inverters

Two types of inverters are commonly used in homes. Which one is the best choice? It depends on your specific needs. 

 

Micro Inverter: Powering Panel by Panel

Each of your solar panels is equipped with a  translator, called a micro inverter. This means that every panel can express its energy in the language your home understands, which is AC power. 

 

Micro inverters maximize efficiency by eliminating the domino effect of power reduction caused by shading or panel malfunction. This ensures that the overall system's output isn't compromised by the weakest link.

String Inverter: Consolidating Energy Flow

With string inverters, multiple solar panels are connected in a "string," and the collective DC power is channeled to the string inverter for conversion to AC power. 

 

While string inverters might be cost-effective for smaller installations, they could be sensitive to shading issues or malfunctions of a single panel, affecting the performance of the entire string.
