WindyNation's inverter cable kit comes with all the cable you need to connect your inverter to the battery bank. The battery cables are manufactured using WindyNation's Power-Flex Welding cable, which is a highly flexible industrial grade pure copper cable. A total of 8 cable lugs (4pcs 5/16" and 4pcs 3/8") are included so that you can attach the correct cable lug mounting stud size that matches your inverter and battery terminals. Also included is a 8 foot piece of 10 AWG grounding cable with ring terminal connectors. This can be used to ground the inverter, if necessary for your application.
