Fuses are super important! If your battery is fused, you are protected against cables catching on fire, and all other sorts of nasties. If your batteries aren't fused, well, you're not protected!

The most common question is, what size fuse do I need? If you are only running DC appliances such as a fridge, LED lights etc, then 50A is usually enough. To be sure, just add up the current draw of all your appliances and then add 20% (multiply by 1.2)

If you are using an Inverter then I suggest you use this handy table:

Inverter Size Fuse Size
100W 30A
300W 60A
500W 100A
800W 250A
1200W 250A
1500W 250A
2000W 350A

For most Caravans, RV's, Boat and Simple solar setups we recommend the 'bolt-on' Battery Fuse Kits offered below. These bolt right onto the positive terminal of your battery bank so you don't have to run any extra wires to have circuit protection - quick and easy!
