Why Do Solar Cells Need An Inverter? (A Quick Guide)

An inverter is one of the most crucial components of a solar panel system.

It is a device that transforms the solar panels’ produced DC current into the AC current, which the electrical grid needs to serve its purpose.

But why do solar cells need an inverter?

This is because an electrical grid needs AC current to function. DC keeps the voltage of the electricity constant in one direction.

As the voltage shifts to negative in an AC circuit, electricity moves in both directions.

One type of power electronics, a class of devices that control the flow of electricity, includes inverters.

Why Do Solar Cells Need An Inverter?

In the modern world, direct and alternating currents are required for different purposes.

While sensitive equipment requires a more direct electricity supply, the grid can function on AC power. DC energy is produced by solar cells using the sun’s energy.

The DC power capacity rises, and the solar panels’ output capacity is released when the solar cells are connected.

Our homes’ AC appliances are powered by solar cells and inverters.

A series of solar panels produces huge amounts of DC electricity, which is then sent to an inverter.

Then, the inverter converts it from direct to alternating current. This illustrates why solar panel inverters are necessary.

Do I Need To Have An Inverter?

A very crucial component of a solar cell system is the inverter. That is why solar cells need an inverter.

It converts the direct current produced by the solar panels into alternating current that may be used on the grid.

It doesn’t matter if it’s alternating or direct current; household equipment still needs the power to run.

If you only utilize solar power for DC-powered home appliances, you can omit the inverter component of the solar panel system.

Your solar panel system must be adjusted to your home’s AC power consumption.

When connecting a solar system to the grid, you must also synchronize its output power with the grid.

This is another justification for installing inverters for solar panels and cells.

What Makes Them Important?

The solar inverter also provides protection against electrical dangers and aids in preventing overload and short-circuit damage.

Solar cells need an inverter because inverters will automatically cut off if there is an excessive amount of current flowing through the system until the issue is addressed.

Because of this functionality, a well-maintained solar panel system with a reliable inverter safeguards your property against fires and other electrical issues.

Connecting The Inverter To Your System:

Now that you know why solar cells need an inverter, you might also want to know how to link the inverter to the system.

How you can connect your inverter to your solar panel system depends on the size of the system.

Direct connections to inverters have the drawback that the inverter may malfunction if the output voltage of the solar panel is higher than the input voltage.

If the output voltage of your solar system falls below the input rating of the inverter, the solar panel inverter can be directly linked to the solar panel.

A solar inverter can be connected to a battery or a power grid. Additionally, it works if connected to an alternator. It’s known as a hybrid or off-grid inverter.

This helps maintain a constant grid supply during the day and at night. Even if the electricity goes out, power will still be available for some time.

If your system has a battery bank, you will want an additional solar panel to power the inverter.

Different Types Of Inverters:

A solar system may include one of several types of inverters.

Every solar panel may be connected to one central inverter in a major utility plant or a mid-sized community solar project.

String inverters link a collection of solar panels together to form a string. The power generated is converted to AC by that converter.

Every panel has a microinverter, which is a tiny inverter. This configuration, while economical, reduces power output even if a single panel encounters problems, such as shading.

The power from the other panels won’t be affected by shade or damage to one panel when using a microinverter, but they can be more expensive.

A system that manages how the solar system communicates with associated battery storage may help both types of inverters.

Solar energy can replenish the battery directly or after conversion to AC.

Solar Inverter Chargers:

Solar inverter chargers are an improved version of a standard inverter.

You will always have power because the inverter charger does not only serve to convert direct current to alternating current but also recharges the battery pack when there is no power.

This is helpful in locations without enough sunlight to charge the battery pack.

If the following applies to you, an inverter charger can be useful in situations where sunlight is extremely scarce or if you wish to have a backup option for when no power is available, such as during a power outage.

The charger will recharge the batteries when they are low and block the electricity from the panels from getting to the batteries when they are full.


Inverters are a vital part of any solar panel system. But why do solar cells need an inverter? Well, mainly because the power produced by your solar cells is in the form of direct current. However, most appliances in your home need alternating currents to function. An inverter converts the direct current to an alternating current. Without an inverter, your solar panel system’s power would go to waste. A better understanding of your solar panel system will help keep it working efficiently for longer; thus, solar cells need an inverter.
