Solar Energy Components Series: Part Three: Solar Inverters

Updated: Jun 5, 2021

What are they?

A solar inverter is an essential part of your solar energy system. This part of the solar energy system allows you to use the power that the solar modules have collected from the sun! In our last posting on solar modules, The energy that comes from solar modules is DC (direct current). So, technically this energy can be used in that form – however, an inverter turns that energy into AC (alternating current) which is better for the electrical appliances and devices in your home and is less likely to create a power surge in your home (see our blog about surge protectors). So, the inverter is the device that directs all of that solar energy to your lights and appliances[1].

How do they work?

We mentioned before that the energy from solar modules is DC (direct current); it can technically be used in that form – however, an inverter turns that energy into AC (alternating current). The energy from the solar module is sent to the inverter then to your fusebox to power your home! If your solar modules generate excess energy, the rest will be sent to the energy grid [2].

Types of Inverters

There are a few different types of inverters on the market currently. These include straight string inverter, optimized string inverters, microinverters and hybrid inverters.

Straight string inverter

A straight string inverter is also known as a central inverter. This type of inverter converts all the DC energy into AC energy and is generally suitable for smaller scaled installations. Check out the diagram below to see how string inverters work[3]!

Optimized String Inverter

An optimized string inverter system has individual units called optimizers installed under each solar module. First, the optimizers are connected to form DC strings. From here, the strings work together and maximize the extraction of the DC power from those individual units and convert it into AC energy[4]!

A microinverter essentially does the same thing as other types of inverters; however, they are much smaller than the traditional string inverters. These types of inverters are placed behind every solar module and make your solar modules more efficient. The microinverter can also be used with a smart app on your phone!

Hybrid Inverters

A hybrid inverter is a type of inverter that works the same as other types of inverters, but it also allows storage of excess energy in a battery system for self-use [5]. In addition, these types of inverters also allow for a backup mode that will give its user a limited amount of power in the event of a blackout [6].
