A solar micro-inverters is a small plug-in device typically used in solar photovoltaic systems, which directly converts direct electrical current produced by a single photovoltaic module into alternating current. This type of inverter is an indispensable part of many solar PV systems as it directly controls the generation of electricity from the sun’s rays. Micro-inversers are available in two types – discrete or constant current and constant voltage. They can also be combined with a converter, such as a Class I or Class II inverter.

The concept of a micro-inverters dates back to the 1950s, but their widespread use came into the limelight following the release of the world’s first micro PV system at the Southern Association for Research Extension (SARCE). The system was designed to test the theory that solar cells could produce power even at night without the aid of an external power supply. A number of homes and businesses around the world were fitted with micro-inverters in order to test the idea. Although initially they proved successful, it soon became clear that there was a limitation to the DC output power generated; the amount of solar energy needed was generally too much for the amount of electricity produced. Since then, many advances have been made in the development of DC solar panels and other forms of alternative energy.

In recent times, with the increased interest in green living, the demand for micro-inverters has grown alongside the development of more efficient solar panels. It is for this reason that many manufacturers are currently developing high-quality solar panels that utilise smaller sized solar panels. These devices are capable of producing enough electricity that the home can operate normally using only one unit of battery installed. Micro inverters that are capable of functioning in this way are termed “small-sized inverters”.

In addition to their use in small systems that generate minimal amounts of electricity, micro-inverters are also used to create a second level of output for systems that require more power output. These second levels are often required when systems are combined with other types of renewable energy production such as wind turbines. To meet this need some manufacturers have developed “task” or “task group” micro-inverters.

One such application is to convert surplus electricity produced by wind turbines into useable household power. In situations where electricity can be generated from more than one solar panel, the most economical method is to utilize all the available solar power systems by connecting them into one centralized unit. In this type of setup the micro-inverters are typically integrated directly into a standard electrical wiring system. As all the electrical power systems in the area are connected into one large electrical panel the overall required electricity output can be greatly increased.

Micro-inverters can also be used to provide a source of renewable energy for heating and air conditioning systems in residential buildings. It is common for people to convert an attic or other out of the way space into a mini-heating or cooling system. In order to accomplish this task it is necessary to connect multiple micro-inverters to multiple solar panels. The total output from these panels can be used to heat or cool the building depending on the desired temperature level.

The most widely known application of micro-inverters is in commercial settings. Many large buildings and factories have large panels mounted on roof tops. DC solar panels are connected into these systems via micro-inverters. As buildings are heated and cooled by DC solar panels, the micro-inverters are able to provide maximum power output. This method is also highly beneficial to the environment because the DC generated by the panels is supplied directly into electrical energy by creating very little pollution.

Micro-inverters are available in a variety of configurations. AC micro-inverters can be small and used as roof access plug in units or larger battery style units that are commonly seen in business applications such as hospitals, restaurants, motels, hotels, banks and even prisons. DC micro-inverters can also be installed as string inverters and plugged into the building’s main electric grid. These larger units are usually installed on roofs or near large trees to provide a more consistent source of power. No matter the application micro-inverters offer a unique and valuable solution for modern day power needs.
