Battery and Inverter Cables
Battery and inverter cables are critical components in your battery-based power system. Most inverter systems require massive amounts of current flow from the battery, so the DC wiring must deliver that current at extremely low resistance for good overall performance. All connections must be clean and tight, and the wiring must be of adequate size. For these reasons, copper welding cable is most often used for battery interconnects and inverter cables. Welding cable is highly flexible, with a thick, durable insulation. In short, all the features that make it perfect for welding, also make it a good choice for battery systems.
Some local electrical codes do not allow the use of welding cable in your battery-inverter system, meaning that it will not pass inspection due to technicalities that have nothing to do with functionality. Although these situations are rare, it is your responsibility to ascertain the suitability of using welding cable in your system.
