A Practice Note discussing the process of connecting an energy generating or battery storage facility to the electric grid and the legal and regulatory framework applicable to the interconnection process. . Sometimes energy storage is co-located with, or placed next to, a solar energy system, and sometimes the storage system stands alone, but in either configuration, it can help more effectively integrate solar into the energy landscape. This allows solar systems to fully integrate and operate seamlessly within a larger electrical infrastructure and further advances the transition to a more sustainable energy system. These inverters are designed to make sure that the solar power is in sync with the grid's frequency and voltage.
