Between 2 p.m. and 3 p.m., the solar energy is also discarded because PV arrays could not generate electricity fully due to the maximum current limit of the batteries when the system is switched to battery storage after the saturation of heating storage.
However, as solar energy is only intermittently available, PV-based standalone systems require an energy storage component, which is often achieved by using a battery bank [2]. Independent of an electrical distribution network, a standalone system generates electricity.
The energy storage side mainly completes the charge and discharge management of the energy storage batteries, and converts the bus voltage to the energy storage battery required DC voltage. For the high voltage energy storage batteries, a single bidirectional BUCK/BOOST circuit can be used [ 12, 13, 14 ].
