Recommended Sizes of Wires and external Fuses
Thefollowingsizesofwiresandexternalfusesarerecommended.Thedistanceof3ft./
6 ft. / 10 ft. is the distance between the battery and the inverter. The running length of
routing of the wire should be considered if the wiring run is not straight but circuitous.
The recommended size of wires will limit the voltage drop to 2% of the nominal battery
voltage(0.24Vfor12Vbatteryand0.48Vforthe24Vbattery)
