The solar panel technology has seen to it that the solar energy gets used sufficiently. This has been powered by the human’s endless needs for energy to perform different functions. Solar energy harnessed from the panels however is in the form of direct current (DC), which has a limited number of its applications. Due to the need for the alternating current (AC) for use in different appliances, the invention and improvement of inverters has made it possible to get AC power from the solar panels. A knockout post to know all the benefits of micro inverters.
In deciding the type of micro inverters for use in a home’s solar panel system, it is important for one to know the different types of inverters in existence. The typical inverter is the string inverter. It is the conventional inverter that is used in converting DC to AC in photovoltaic cells. These are cells that generate electric current when rays of light of certain wavelength and frequency land on them. These cells when put together forms a panel. It is a single unit that is in the form of a meter box and connected to one or more modules of solar panels. The panels are connected together combining their output as one single output from a massive panel. The string inverter then converts the power to AC and then feeds it to the power grid. String inverters are considered to be cheaper since there is only one inverter to serve all the panels rather than each panel with its own inverter. They also have a monitoring face on top which makes them easier to monitor. Despite the advantages, there also exists disadvantages. The con is that whenever the inverter fails, the whole system becomes stagnant, since it is only single inverter that feeds power to the grid.
On the other hand, micro inverters are small types of inverters which are attached to each panel of the solar panel system of a house. They are made in such a way that they can only handle the output from a single panel. Each of the micro inverter converts the DC from it’s the panel it is attached to AC and then feeds the power to the grid. These inverters have advantages in that each of the unit panel is independent since each has its own inverter. Should any of the panels be shadowed or covered, the other panels will continue to dissipate DC power to their particular inverters. They are also considered to be safer since there are no high voltage DC outputs involved. The outputs are managed in single units rather than one burst of energy as in the string inverters.
Energy from the panels are also stored for use during the night. Apart from the inverters feeding power to the grid, lithium batteries for solar are used to supplement power. The power output however is in the form of DC, hence can be converted to AC using the inverters before use. There is another advanced method of using the dual battery solar system which offer support to the main assistance to the standard battery.
