Types of Solar Panel Inverter

A solar panel inverter is an important part of any solar energy system. It takes the direct current (DC) output of a solar panel and converts it into alternating current (AC), which is what most household appliances run on. There are a variety of solar panel inverters on the market, each with its own set of features and drawbacks. Here’s a quick rundown of some of the most popular kinds!

String Inverters

String inverters are the most common type of solar panel inverter, with most small-scale systems using this style. String inverters can be placed in series or parallel to power larger installations with more panels. The most significant limitation with string inverters is that they require each panel to have a microinverter, which takes the direct current (DC) generated by each solar panel and converts it into alternating current (AC), creating a lot of excess cabling.

Central Inverters

A central inverter, or microinverter, is used with most large-scale solar installations. These systems can power entire buildings with one central inverter through the use of string inverters that convert the direct current (DC) from each panel into alternating current (AC). Central inverters are expensive, but can often lead to a more efficient system.

PWM Inverters

Pulse Width Modulation (PWM) inverters are a type of solar panel inverter that is growing in popularity. They are less expensive than central inverters and work by taking the direct current (DC) from each solar panel and turning it into alternating current (AC) using an electronic switching circuit. While PWM inverters don’t have the efficiency of central inverters, they are a good option for homeowners looking to save money without compromising performance.

Off-grid Inverters

An off-grid inverter is typically used with a solar energy system that has battery backup. These systems are often more expensive but can produce consistent power, even during an outage. Off-grid inverters control the amount of electricity flowing from the panels to the batteries, ensuring that they’re always fully charged and ready to provide power as needed. Off-grid inverters are a good option for homeowners who spend a lot of time off the grid, as they can provide access to electricity 24 hours a day.

Grid-tied Inverters

Grid-tied inverters are the most common type of solar panel inverter. They’re used in most residential and small commercial solar installations and work by taking the direct current (DC) output of solar panels and converting it into alternating current (AC), which is the standard for household appliances. Grid-tied inverters are connected to the electrical grid and used to balance the amount of energy being generated by the solar panels with the amount of energy being consumed by the home. This helps reduce the amount of energy purchased from the grid, saving homeowners money on their electric bills!

Last Words

Choosing the right kind of solar panel inverter can be confusing, but choosing a reputable solar panel installer is the best way to ensure that your system will meet your specifications. Since there are so many different kinds of inverters on the market, it’s important to do thorough research before placing an order for a new system.
