6 FAQs about [12v 400A what size inverter should I use]

What size wire does a 2000 watt inverter use?

A 2000 watt inverter will draw around 208 amps with a 12 volt input. This would require a 2 AWG wire at 10ft or less in length. What Size Wire for a 3000 Watt Inverter? For a 3000 watt inverter it is common to use a 0 AWG wire size. This is because at max load of 3000 watts at 12 volts would draw 250 amps.

How many amps can a 2000 watt inverter handle?

To work out amps you use the formula – watts ÷ volts = amps. For example, if you’re using a 2000 watt inverter with 12V input it would be 2000W ÷ 12V = 166.6 amps. So you need a wire that can handle more than 166 amps. Now let’s find the wire size using amps on this table below using this inverter wire size calculator:

How to calculate inverter size?

Using the Inverter Size Calculator is quick and easy. You’ll need three inputs: Total Wattage (W): This is the total power consumption of all the appliances or devices you plan to run through the inverter.
