What Is a Solar Power Inverter?

Solar power inverters convert direct current (DC) electricity produced by photovoltaic panels to alternating current (AC) electricity. This AC electricity can then be used to power a variety of electrical appliances, such as refrigerators and TVs.

There are a few things to keep in mind when choosing a solar power inverter for your home or business. Among them, it’s important to select the right size for your solar system.

Protection from Hazardous Electrical Faults

Solar power inverters are equipped with arc-fault detection and circuit interrupter circuits to protect against dangerous electrical faults. They are designed to shut down when they detect an arc flash, and they also disconnect from the grid in case of a sudden drop in voltage or frequency.

Inverters can be divided into string inverters, which connect multiple solar panels together to form a single unit, and microinverters, which convert electricity from individual solar modules. Each type offers different benefits and may have different warranty options.

PV systems are susceptible to a variety of dangerous electrical faults that can cause severe burns or even death if they come into contact with skin or people. This includes insulation faults, reverse current in a PV module and overloading cables or equipment.

Increased Energy Efficiency

A Solar power inverter converts the direct current (DC) energy produced by your solar panels into alternating current (AC) energy that can be used for many electrical appliances at home. It can also be used to store the excess electricity you don't use and feed it back into the grid for extra energy credits.

Inverters are a key part of the electrical grid. They are responsible for providing a variety of grid services, such as reactive power, which synchronizes voltage and current to maximize the electric system's overall efficiency.

As the number of connected solar systems increases, grid operators have to provide smarter inverters that are designed to respond to changes in voltage and frequency and help stabilize the electric grid against disruptions.

Inverters have to be able to handle fluctuating temperatures and stand-by power during zero-crossing periods, when they have to switch off their output while they wait for the panel's AC energy output to rise above a certain voltage threshold. This varies from system to system and requires some planning.

Feed-in Tariffs

A Solar power inverter converts the energy produced by your solar panels into AC mains electricity for use within your home. When your system produces more energy than you need, your electricity retailer will pay you a kilowatt-hour rate for every kilowatt-hour of excess power you send back to the grid.

Feed-in Tariffs (FITs) are a popular policy mechanism in many countries around the world. They encourage renewable energy production and help make the economic case for renewables by providing long-term contracts and guaranteed prices.

In the UK, solar PV systems are able to send a large proportion of their electricity production to the grid in exchange for payment. This is known as net metering and can save you money by reducing your dependence on your electricity provider.

Solar power inverters measure the amount of energy generated by your solar panels each day and display this on an electronic screen. This information can be viewed from anywhere at any time, including via an app on your smartphone.

Protection from Temporary Power Outages

Solar power inverters are a key component of many home solar systems. They convert DC solar energy into AC electricity, which is used by your household appliances and electric devices.

When the sun goes down, a typical grid-tied solar system shuts off automatically to prevent sending excess energy onto the grid. This is a safety precaution to avoid putting utility line workers at risk when they’re trying to fix broken lines and reconnect the electrical grid.

If you have a solar-plus-storage system, your inverter can disconnect your home from the electric grid during a power outage and send power to your batteries for a few days of electricity. However, this may not be sufficient for all your needs.
