Solar, photovoltaic and off-grid technology power systems tend to use solar inverters to transform direct current (DC) that they have generated into alternating current (AC), which is consumed on site or sent to a power grid. The inverters are normally used with battery systems or directly to power different devices. These tend to have different identifying features, which are intended for use with photovoltaic arrays. There are inverters that are used to tie PV arrays into power grids to ensure that there is protection from the phenomenon of islanding.
When residential solar or photovoltaic panels are used to generate electricity from solar radiation, the output resulting from this is normally variable direct current. This is similar to the electricity that is found in batteries, and it has to be changed into alternating current before it can be used to power businesses or homes. The process of changing DC into AC is usually performed by inverters, even though many of these devices are designed to work using non-variable direct currents. Unlike other types of inverters, solar inverters are designed to work with variable direct current that has been generated by photovoltaic arrays.
One of the specialized features that have been built into solar, photovoltaic and off-grid technology inverters is the maximum power point tracking (MPPT). This technology ensures that solar inverters apply loads to every PV cell to obtain the highest level of power. Different types of algorithms can be used in these systems, even though they are usually intended to increase the efficiency in a general manner. The two different types of solar inverters are usually defined by whether they are meant for use on grid-tied or off-grid applications. Off-grid inverters are normally used to power homes and businesses directly without the need to connect to any external power grid.

Since solar, photovoltaic and off-grid technology does not involve connection to an external power grid, any premises that is using this power is not likely to suffer from power shut off. This is usually called islanding. Many solar inverters have measures for anti-islanding to prevent this from happening. When there is presence of a grid, inverters that have circuitry which can be used to intentionally cut the premises off the grid can be used to ensure that the photovoltaic array provides electricity to the local site only. Anti-islanding features are found in some inverters and these can be utilized by PV arrays before being tied to grids. Click here to purchase high quality solar panels.
