In general, if your 2000 Watt inverter is running on a 12V battery bank, it could draw as much as 240 Amps of current. If your battery bank is rated at 24 Volts, the 2000W inverter could draw up to 120 Amps of current. If the battery bank is rated at 48V, the amp draw would not exceed 60 Amps.
A 12V 2000W inverter running at maximum load draws 166.6 amps an hour. Divide the watts consumed per hour by the voltage and you get the amps. In this example, 2000 watts an hour divided by 12 volts equals 166.6 amps. The following calculations assume you have a high quality inverter that can draw maximum power.
The amp draw for a 2,000-watt inverter depends on factors such as the battery bank’s voltage rating and the unit’s conversion efficiency. But a good starting point is 167 amps if the 2,000-watt inverter runs on 12 volts. In this post, you’ll learn how to calculate the amp draw of a 2,000-watt inverter.
If you have a battery bank connected to your system or your appliance consumption is listed in amps, knowing the answer is a must. A 12V 2000W inverter running at maximum load draws 166.6 amps an hour. Divide the watts consumed per hour by the voltage and you get the amps. In this example, 2000 watts an hour divided by 12 volts equals 166.6 amps.
If your 2000W inverter is running on a 48V battery bank, the fuse or circuit breaker should be rated at 70-80 Amps. If your 2000 Watt inverter is rated for 12VDC, you could use a 225 Amp fuse or circuit breaker, but only if the battery’s low voltage cut-off point is set to 12 Volts (as opposed to 10 Volts).
It depends on the voltage of your system. At 12 volts, a 2000 watt amp pulls about 166 amps (2000W ÷ 12V = 166A). At 24 volts, it pulls around 83 amps (2000W ÷ 24V = 83A). This is why it’s so important to use the right wire size and fusing when installing your power inverter 2000w. What size battery do I need for a 2000 watt amp?
