How Is Battery Cable Size for a 2000 Watt Inverter Determined?
To determine the battery cable size for a 2000-watt inverter, start by understanding the current draw. A 2000-watt inverter typically operates at 12 volts. You can calculate the current (in amps) using the formula: Current (Amps) = Power (Watts) ÷ Voltage (Volts). So, for a 2000-watt inverter at 12 volts, the current draw is approximately 167 amps (2000 ÷ 12).
Next, consider the length of the cable run. The longer the cable, the more resistance it has, which can cause voltage drop. Voltage drop is not ideal for inverter performance. Use the American Wire Gauge (AWG) chart to select the appropriate cable size based on the distance. For instance, for a cable run of up to 10 feet at 167 amps, you would typically require 1/0 AWG cable. For runs longer than 10 feet, increase the cable size to reduce voltage drop.
Additionally, factor in the inverter’s surge capacity. Inverters can draw significantly more power at startup. For a 2000-watt inverter, the surge can be 2 to 3 times the running power. Thus, ensure the cable size accounts for surge current as well.
In summary, calculate the current draw from the inverter’s wattage and voltage, consider the length of the cable, and adjust for surge capacity. This systematic approach ensures you choose the correct battery cable size for optimal performance.
