A: The PI100CL power inverter is rated at 100W, but the maximum power output for the inverter is 150W. As a rule of thumb, the fuse size for the inverter should be 125% - 175% of the calculated current. This allows for margin of safety and helps to avoid nuisance tripping. The current input for the power inverter is 13A. Current (A) = Power (W) / Voltage (V). 150W / 12V = 12.5 or 13A. A 20A fuse is within the recommended 125% - 175% range of the calculated 13A current.
