Grid Interconnection & Battery Storage

A PV array has to connect into the building's electrical system and, usually, the grid, and how it integrates (and whether it includes battery storage) determines how much of its value the building actually captures. Two identical arrays can return very different amounts depending on how much of their output is used on site. This lesson covers grid-tied systems, the self-consumption goal, battery storage, off-grid and hybrid configurations, and the monitoring that protects the investment.
