What is a Solar Inverter?

A solar inverter is one of the most important components of your solar energy system. It converts DC electricity into AC electricity, which is what your appliances and electronics use.

The inverter also helps ensure that your electricity doesn’t feed into the grid unless you want it to, which protects line workers from being injured.

What is a Solar Inverter?

The solar inverter is the heart of any solar power system. It takes the variable direct current (DC) output from solar panels and transforms it into alternating current (AC). AC is the type of electricity that most homes use. It’s also the type of electricity that utilities run on.

Solar panels are designed with semiconductor layers of crystalline silicon (a combo of positive and negative). When the sun shines, photons knock electrons loose from the layers and create electric current. This energy is then channeled through a series of transistors that open and shut in pairs. This causes the electric current to rise and fall. This energy can then be used to power appliances in your home or fed into the utility grid.

Regardless of how it’s used, the DC electricity needs to be transformed into AC before it can power your appliances. Without a solar inverter, the electricity wouldn’t be usable. The inverter is also responsible for monitoring and tracking the energy production of your solar panel systems. It can also provide safety features, like a shutdown mechanism in the event that something goes wrong with the system.

There are two types of solar inverters – microinverters and string inverters. Each performs the same basic function, but they differ in how they work under different conditions.

Types of Solar Inverters

When sunlight hits solar panels, it creates a combination of positive and negative semiconductor layers that generate energy. These layers transfer electrons that run around the panel and bump into other layers creating electric currents, known as direct current (DC). The DC power is then sent to an inverter where it’s turned into alternate current (AC) to supply your home with electricity.

The type of inverter you choose will depend on the size of your solar system, SOLAR INVERTER your home’s needs and any grid-tie or off-grid requirements you may have. In general, you will want a larger inverter than your system’s nameplate power rating to ensure that it can handle your average day-to-day energy usage and any excess production you wish to feed back to the grid.

Central inverters are typically used for larger solar systems and work by converting the DC power from multiple solar panels into alternating current at a single location. String inverters are another popular option for residential solar energy systems and offer the ability to connect a number of panels together. Microinverters perform the same conversion of direct current to alternating current but at each individual solar panel. This helps to avoid shading issues that can affect the entire panel array.

Both types of inverters have their pros and cons. A good installer will help you determine the best solution based on your specific situation.


The cost of a solar inverter depends on the size and brand of the inverter, as well as installation costs. Higher-quality brands tend to have longer warranties and better customer service, which can reduce hassle down the line. Homeowners should also consider financing options and warranty coverage when budgeting for a new solar inverter.

The inverter converts the variable direct current, or DC, output from your solar panels into the alternating current, or AC, electricity that powers household appliances. solar panel It can also provide energy to your grid-tied system and allow you to generate additional income through net metering.

A string inverter is usually installed near your house’s main power panel or electric meter. It is wired to a group of solar panels that are connected together, called a “string.” If shade covers one or more panels for just two hours a day, the entire string will underperform because they’re all linked to each other. A microinverter, on the other hand, addresses this problem by placing one inverter under each panel.

A microinverter is more expensive than a string inverter because it utilizes more sophisticated technology. However, it will save homeowners money in the long run because it can prevent costly repairs and boost energy production. It can also help extend the lifespan of your panels by reducing maintenance and repair expenses.


The solar inverter converts the direct current (DC) produced by the PV panels into alternating current electricity which is used for household power. It’s usually installed close to the main service panel or electric meter of your home in a grid-tied system. It may also be part of a battery backup system to provide energy during outages or in remote locations.

There are two types of solar inverters: string inverters and microinverters. String inverters connect a group of solar panels, or a “string,” to one inverter that then converts the DC power from all the panels into AC. This type of installation is cheaper but if a single panel experiences shading or damage, it can reduce the energy production of the entire string. Microinverters, on the other hand, are mounted on each panel and produce their own AC electricity.

Before starting the inverter, make sure that all of the wires are connected properly and that the switch on your AC breaker is turned off. If you’re not familiar with electrical wiring, consider hiring a licensed electrician to help with this step.

After the inverter is installed and connected to a battery, it’s important to test its performance to ensure that it is working correctly. You should also monitor your energy production regularly. If you notice a drop in production, it’s important to address this immediately.
