This is an intensive six-week training with Master Trainer Christopher LaForge. PV systems that employ batteries require significant design considerations. Whether using batteries to back up your utility grid or as the basis of a stand-alone, off-grid system, choosing the correct battery and sizing it correctly is challenging. This course provides in-depth analysis of the issues surrounding the use of batteries for PV applications. It covers battery design, specification, use, and maintenance. The course capstone project is creating the design for a battery-based solar PV system.
