Solar inverters are necessary for a home photovoltaic system.

Your house runs on alternating current (AC), while solar panels generate direct current (DC). An inverter changes DC to AC power.

Solar Inverters

Solar Panels Online selection of inverters gives you several options for converting energy from direct current (DC) to alternating current (AC) through an electrical switching process. Inverters are necessary in solar panel installations. also carries all of the inverter accessories you require, including wiring, fuses, and breakers.

You can choose from grid-tie or off-grid inverters. Grid-tie inverters generally operate without batteries, allowing you to feed your excess energy directly into your local utility grid. Most utilities accommodate net metering, requiring that your utility reimburse you for this energy. Off-grid inverters are best suited for on-the-go or remote solar applications, as well as for those homeowners living where no net metering program is in place. With off-grid inverters, your solar energy is fed into batteries where it is stored until it is used.

What is a solar inverter?
A solar inverter is an important piece of the solar energy installation. Its purpose is to change the direct current (DC) electricity that is generated from a photovoltaic solar panel into an alternating current (AC) that can be used by in-home appliances and the community electricity grid. Because all photovoltaic panels produce electricity in DC, an inverter is required for all solar power systems to make the electricity usable.

The solar inverter is one of the most important parts in a renewable energy system. Because of this, many people fall into the trap of underestimating the needs for a solar inverter and purchase one that handles a smaller capacity than necessary in order to save money. One of the recommendations to avoid making this mistake and keep the up-front costs of a solar energy system down is to initially purchase fewer solar cells and add more later rather than skimping on the inverter.

There are many manufacturers that are competing in the solar inverter market. While there have been a lot of American-made inverters in the past, in recent years it's been discovered that they're not always operating at their advertised efficiency, resulting in several companies going out of business. This has opened the market up to several international companies, and many of the most recognized solar inverter brands are European.

One of the biggest issues of a solar power system is efficiency. The cost of building and installing a system is often expensive, and those who are willing to make the financial investment in solar energy want to be sure to get their money's worth. Not only do the solar cells need to convert the sun's energy to electricity efficiently, but the solar inverter has a responsibility in efficiency as well. Manufacturers of inverters are working to improve their products' efficiency in order to make the products more marketable and attractive to those interested in solar power. To boost performance and energy production of your solar energy systems, a solar power optimizer might be a good solution. Any possibility of saving more money in the use of a solar power system will increase the odds of people converting to solar power and easing the demands of the fossil fuels and oils on which American society so heavily relies.

Solar inverters that are tied to the community's electricity grid help regulate the currents between the building the solar energy system is powering and the power lines of the grid. Grid-tie systems that feed into and from the grid are usually required to have anti-islanding protection built in. The anti-islanding ensures that if a fault occurs within the grid, the solar powered system will disconnect from it immediately to prevent feeding more electricity into an already hazardous situation. Reconnecting to the grid can sometimes be complicated, but in order to have a completely safe system, it is required to follow the anti-islanding regulations set forth by local power companies.

One who is considering designing and installing a solar energy system for his or her home should hire a professional to assist in making sure the system is built properly. There are many variables to take into account, including the size of the home, the electricity use of the home, possible future fluctuation in the energy use of the home, as well as the types and sizes of the photovoltaic cells and solar inverters necessary to keep the system running smoothly.
