An off-grid (stand-alone) PV system is a solar power system that uses arrays of solar panels to charge banks of rechargeable batteries. This allows for energy storage and use at night when energy from the sun is not available.
For a grid-connected PV system, inverters are the crucial part required to convert dc power from solar arrays to ac power transported into the power grid. The control performance and stability of inverters severely affect the PV system, and lots of works have explored how to analyze and improve PV inverters’ control stability .
In the grid-connected consumer ends. Power quality is a major concern, while injecting PV to the grid and system is the challenging area. Off-grid solar PV system is independent of the grid and provides freedom from power quality issues and electricity billing.
An off-grid Solar System, also known as a standalone PV system, includes battery banks, inverters, charge controllers, battery disconnects, and optional generators.
Battery energy storage is the important component in the off-grid solar PV system. Due to load and PV output variations, battery energy storage is going to have frequent charging and discharging. So the type of battery used in a PV system is not the same as in an automobile application.
Power fluctuation is the nature phenomena in the solar PV based energy generation system. When solar PV system operates in off-grid to meet remote load demand alternate energy sources can be identified, such as hybrid grid-tied or battery storage system for stable power supply.
