Choosing the correct battery cable is important to prevent unwanted power loss and even damage to equipment and property. It’s easy to choose the correct cable as many inverter manuals have helpful wire sizing tables. As a rule of thumb, if your inverter requires a 175A battery breaker, use a 2/0 cable. If your inverter requires a 250A breaker, use a 4/0 cable. Our cables are UL listed and have lugs for easy connections.
