balance of system (BOS)

The Balance of System (BOS) refers to all the components in a system, particularly in renewable energy setups like solar power, that are not the main generating unit. In solar systems, BOS includes everything necessary for the system to function effectively, such as wiring, inverters, mounting structures, batteries, and safety equipment. While the solar panels generate electricity, the BOS components ensure that energy is safely handled, stored, and delivered for practical use. Essentially, BOS is crucial for the overall performance and reliability of energy systems.
