The short answer: it solves the two biggest headaches of renewable energy—intermittency and cost. A hybrid system is basically solar panels, a smart inverter, and lithium batteries talking to each other in real time. When the sun is strong, panels feed the loads first. . wide range of energy storage technologies are available, but we will focus on lithium-ion (Li-ion)-based battery energy storage systems (BESS), although other storage mechanisms follow many of the same principles.
