First the bidirectional AC-DC converter operates in two modes, namely as front-end rectifier when power battery is pushing back power to the source . electrical power transfer and battery charging . During charging mode, the charger acts as a buck converter and as a boost converter while discharging.
Therefore, a bidirectional DC fast charging station equipped with a new controller is proposed to solve the voltage fluctuation crisis, in which the switching of the existing power converter is controlled by the new constant current/reduced constant current method.

For off-grid systems, 48V battery voltages offer many advantages over 12V or 24V batteries, particularly for larger systems. AS shown in the example below, 48V systems result in a reduced current draw for the same power output, leading to lower resistance, cable losses, and voltage drop.
To correctly size an off-grid battery system, several factors need to be considered, including the daily load (kWh), inverter power rating, peak loads, and number of days of autonomy. Below are the steps to ensure the battery system is sized correctly to match these requirements.

Building-integrated photovoltaics (BIPVs) systems are going to effectively participate in fulfilling the net-zero-energy building (NZEB). BIPVs systems that are broadly accepted for buildings can completely guarantee their energy needs from RERs [3, 4].
The high cost of electricity in BIPVs can be mitigated by the supplementary integration of PV panels with ESSs. This is necessary to store the excess energy during periods of low demand of energy and return it to the buildings during periods of high energy demand for energy and/or low availability of renewable energy.
