The introduction of advanced energy storage, lithium chemistries, has revolutionized the market for grid-connected solar. More than simply pushing energy to the grid, modern residential solar systems require intelligence and controls that can respond to changing and varied grid-connection and safety standards and manage behind-the-meter energy consumption to reduce power bills.
