Go Power's GP-DC-KIT3, GP-DC-KIT4 and GP-DC-KIT5 provide the large-gauge cable, fuse protection and mounting parts used to connect compatible 12V inverters to an RV battery bank. The wattage class determines the kit—not the outward appearance of the inverter.
Battery, fuse and inverter connection overview
In a correctly protected installation, the positive lead is fused close to the battery and the negative lead returns to battery negative. This simplified drawing identifies the components; the manufacturer's manual governs polarity, mounting, conductor selection and torque.
Which GP-DC kit fits your inverter size?
Go Power's model-selection table lists the following for 12V inverter output ratings. These are general manufacturer selection ranges, not universal compatibility with every inverter. A 24V system can require a different kit and wiring specification.
| Model | 12V inverter size | DC protection | Battery cable | Cable length |
|---|---|---|---|---|
| GP-DC-KIT3 | 1,100–1,800W | 200A fuse block | #2 AWG | 10 ft |
| GP-DC-KIT4 | 2,000–2,500W | 300A fuse block | 2/0 AWG | 10 ft |
| GP-DC-KIT5 | 2,600–3,000W | 400A fuse block | 4/0 AWG | 10 ft |
The kits include 10-foot battery cables, the fuse block, cable ties, clamps and mounting screws. For GP-DC-KIT3 the fuse block is FBL-200, for KIT4 it is FBL-300, and for KIT5 it is FBL-400. The kit does not replace a separate inverter chassis-ground connection.
