In plain language, master electrician and solar installer Bruce Hankins explains AC coupling, the combining of a grid-tied solar electric installation with an off-grid battery backup system.
As the world turns to sustainability, solar enriches our lives. SAVING SUNSHINE takes a look at today's developments in solar electricity and its increasing role as power provider.
Combining the best features of off-grid, stand-alone solar installations with grid-tied systems that provide distributed generation, photovoltaic systems have evolved into AC-coupled systems. They provide back-up, stand-alone electricity while also using renewable solar energy for our everyday electrical needs.
This combination of renewable energy and energy storage connects multiple inverters with maintenance-free batteries and opens the door to energy independence in a sustainable, low-carbon future.
Teachers, electricians, system installers, architects, owners of grid-tied systems and solar advocates will find the clear explanations in SAVING SUNSHINE helpful in learning the specifics of an AC-coupled system and how it forms a local distribution system to deliver electricity in a more reliable and environmentally friendly manner.
