Inverters

Inverters

Solar Inverters, sometimes called PV inverters, are types of electrical inverters which are developed to change a DC (direct current) voltage from photovoltaic arrays into AC (alternating current) currents which in turn are used to power home appliances and some utility grids. These solar inverters are very popular nowadays as electricity costs continue to rise. Also, this helps conserve energy for future use.

Functions of Solar Inverters
The engineering of these solar inverters and solar panels are designed like pieces of puzzles which should fit together in order to function. Conclusively, these solar inverters are programmed to hook up to a specific count of solar boards. The cost of inverter is practically 10 percent of the total cost of the solar board. We have to take note that these solar inverters do not have useful lives equally long as that of solar panels. This means you have to replace your solar inverters from time to time for you to use your solar system for its remaining useful life. For a solar inverter to work efficiently it should have adequate solar panels connected to it. Lesser or more panels that are connected to it could cause it not to function properly. Consequently, it should have at least 95 percent of panels hooked up to obtain optimum performance.

The Stand Alone Solar Inverter
These standalone solar inverters are called such because they do not need to be hooked up into a solar panel. Instead, it draws its direct current (DC) power from batteries which are charged by photovoltaic (PV) arrays or other resources such as engine generators, hydro turbines and wind turbines. There are a lot of these standalone inverters which integrate vital battery chargers to refill the battery coming from an alternating current (AC) source whenever possible. Because these inverters are isolated from utility grids, they do not require anti-islanding protection.

The Grid Tie Inverters
The grid tie inverters match the phase alongside a utility charged sine wave. These grid tie inverters are also programmed to automatically turn itself off during power losses to ensure safety. Hence, these inverters do not provide emergency power during these times. It is recommended for a home which is powered by a utility grid to use a grid tie inverter in their solar system for them to take advantage of net metering. Grid tie inverters require their system to be installed with anti-islanding protection. Islanding is a process where grid tie inverters are fooled that a utility grid is still functioning even if it has been turned off. It takes place due to load circuits that resonate in the electrical system.

The Battery Backup Inverters
The battery backup inverters are extraordinary inverters which are developed to get energy from batteries and manage the energy charge it got from the battery through the onboard charger, and brings the surplus energy to your utility grid. These battery backup inverters are able to supply alternating current (AC) power to selected areas which require energy during a power outage. They are required to be installed with an anti-islanding protection.
