Hybrid power systems for off-grid locations: A comprehensive review of design technologies, applications and future trends
Figs. 1 to 3 show different hybrid configurations for off-grid applications, Fig. 1 combines solar photovoltaic, wind energy, diesel generator, and battery as a storage element to power load at the BTS site. Fig. 2 depicts a single-source energy system using the battery as a backup for supplying both the DC and AC load for off-grid applications.
