BESS stands for Battery Energy Storage System and refers to larger, dedicated battery storage systems that can be connected to various energy sources, including solar panels.
The system can also function as a standalone energy storage solution without necessarily being directly connected to a solar PV system.
These systems are ideal for larger companies, industries, or grid operators that need to manage large amounts of energy and ensure a stable supply. They are also relevant for large solar parks where the aim is to optimise energy storage and security of supply.
