3.5M Galvanized Rail

As a quick refresher on battery cable—battery cable is a rigid single-conductor wire made of heavy gauge copper. It’s typically insulated with PVC or XLPE and used to safely link between Inverter and battery for a more efficient and safer connection on a solar or backup system.

MC4 connectors are single-contact electrical connectors. They are commonly used for connecting solar panels. MC4 stands for “Multi-Contact, 4 millimetre”. It is a standard in the renewable energy industry. An MC4 connector enables the easy construction of strings of panels.
