Fuse for DC systems These fuses are very suitable to be placed between the battery and the inverter, in order to protect the inverter in the event of an unintentional high overload. Powers available from 100 to 500A. You also need a base to fasten it on, which you can find HERE! How to calculate the size of the fuse you need – If the power of the inverter is 1000W, for example, and it is at 12V, then we divide the power by the voltage. Or 1000/12 which equals 83.33A. A suitable fuse in this case would be 100A. The fuse can withstand a few seconds of overload, as do most inverters, so there’s no point in overclocking it. Size 80/20/8mm
