Inverters play an indispensable role within the renewable energy industry. They are the bridging technology that facilitates the use of renewable energy in systems and grids which have been designed for AC power. For instance, when you install a residential solar panel system, the power harnessed from the sun is generated in DC. However, most domestic appliances require AC. Subsequently, the green power generated by your solar panels would be useless without an inverter to convert the power into a usable form.
Moreover, there are different types of inverters used in the renewable energy industry including string inverters, central inverters, microinverters, and battery inverters. Each comes with their unique sets of benefits and drawbacks, depending on the size, complexity, and needs of the specific system they are designed to support.
Inverters are not only restricted to ensure interface compatibility between renewable energy sources and conventional systems. They are fundamental for the function of energy storage systems alike. For instance, when excess solar or wind power is stored in a battery for later use, it is stored as DC. When it needs to be used, again, like for use in our daily appliances, an inverter is required to change it back to AC.
Regarding their role in carbon accounting, inverters indirectly contribute to measuring an organization’s carbon footprint. Specifically, the efficiency of an inverter affects how much renewable energy is captured and utilized. This performance can be used in estimating the reduction of greenhouse emissions when replacing fossil fuels with renewable energy. An efficient inverter thus aids in a superior carbon footprint for an organization using renewable energy sources.
