Charging occurs when your photovoltaic panels convert sunlight into electricity, then this surplus energy is stored in batteries. At the heart of every solar setup are two opposing operations: solar panel charging and discharging. Discharging begins when those batteries release stored energy to. An energy storage system (ESS) for electricity generation uses electricity (or some other energy source, such as solar-thermal energy) to charge an energy storage system or device, which is discharged to supply (generate) electricity when needed at desired levels and quality. Discover industry best practices, real-world case studies, and expert tips to maximize ROI on solar investments.

In this article, we will define common modes of operation for solar-plus-storage microgrid systems, explain the transitions from one mode to another, and provide a short list of key questions to ask early in the development process. The process of disconnecting and later reconnecting to the grid is complex and specific to each microgrid project, and a document developed to aid in system design, called the Sequence of Operations, clarifies how a microgrid is intended to behave. Sometimes two is better than one. Coupling solar energy and storage technologies is one such case. For homeowners, installers, and DIY.
