Surge protectors protect electrical equipment from voltage spikes. While circuit breakers protect wires from starting a fire due from too many amps (amount of electrical current), surge protectors protect your appliances from power surges, which is a brief spike in voltage (electrical power or force)

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.
