At ChargingChargers.com, we carry several inverter installation kits, of differing gauge wire and fuse capacity. We recommend checking the owners manual of your inverter for specific cable gauge and fuse capacity. Bigger doesn't hurt; smaller can be dangerous. Our inverters list the recommended kit on the same page as the inverter. The kits have battery lugs installed at all ends. The inverters that require pin terminals have those included with the inverter. An appropriate size fuse and fuse block are included. High quality, high temperature, high strand count UL listed cable.
For more information, see our inverter tutorial.
