What is a solar inverter?
Solar inverters are components that are commonly found in photovoltaic (PV) energy systems. The purpose of the solar converter is to transform a direct current (DC) generated by the PV system into an alternating current (AC) that can be sent to the power grid or consumed on site. These inverters can be used either in accordance with battery systems or for direct power of certain devices. They also tend to have several identification features to be specially designed for use with PV fields such as maximum power monitoring (MPPT). Some inverters that are used to connect the PV field to the power grid also have protection from the island phenomenon. It is similar to the type of electricity found in batteries and must be changed into an alternating stream before it can power a house or business. The DC change process is made by inverter, although most of these devices are designed to work with non -free current. Unlike most other inverters, the solar converter is designed specifically for working with PRoměný dc generated PV field.
MPPT is one of the specialized features that can be built into a solar inverter. This technology allows the solar converter to apply the load to each PV cell to obtain the highest energy level. Several different algorithms can be used in MPPT systems, although they are all intended to increase efficiency in general.
The two main types of solar inverters are defined by whether to be used in applications with an extraordinary grid or grid. Inverters outside the network are used to direct a house or company that does not receive electricity from any external source. Units bound to the grid are required for applications where the home or company is connected to the extra power grille. In addition to providing energy for local locations and batteries charging reserves are also able to return excess electricity to the system. Because the spaces canReceiving energy from the grid or from the PV field in place, further preventive measures may be required.
In most cases, the inverters are to turn off the grid inverters if the spaces are disconnected from the external power supply network. Some circumstances can lead a solar converter to continue working after such disconnection, which is a phenomenon known as the island. Many solar inverters contain measures against Iceland to avoid this, and such features are sometimes required by local tools before the PV field can be tied into the grid. Other inverters have circuits that can deliberately cut off the grid space so that the PV field provides electricity only for the local location.
