Copper busbars offer excellent conductivity and are ideal for high-current applications. They're commonly used in solar battery banks and are often tin-plated to resist corrosion. Aluminum busbars are lighter and more cost-effective than copper.
[pdf] A terminal block, or battery busbar, is a specific type used in battery systems, including those in solar power installations. It serves a similar function as a regular busbar, but it is specifically designed to connect multiple batteries in a battery bank.
