Mar 3, 2025 · How Many Batteries Do You Need for a 3000 Watt Inverter? Now that we''ve got the basics down, let''s determine how many batteries you''ll need to power a 3000 watt inverter.
If the 3000W inverter is running on a 24V battery bank, it can draw up to 175 Amps of current. If the battery bank is rated at 48V, the amp draw will not exceed 90 Amps. This is assuming the DC-to-AC conversion efficiency of the inverter (@ 3000 Watts) is around 85%.
For example, if you were to connect the same 3000-watt inverter to a 24-volt battery bank, the amp draw would be halved to around 125 amps: Amps = 3000 watts / 24 volts Amps = 125 amps What can a 3,000-watt inverter run?
A 3000 watt inverter is a powerful tool that can convert DC power from a battery or other power source into AC power that can be used to power appliances and electronics. But how many amps does a 3000 watt inverter draw?
You can calculate the maximum amp draw of your 3000 Watt inverter using the following formula: Maximum Amp Draw (Amps) = (3000 Watts ÷ Inverter’s Efficiency (%)) ÷ Lowest Battery Voltage (V) Inverter’s efficiency: This is the Output Power vs Input Power ratio: Inverter’s efficiency = Output Power (Watts) ÷ Input Power (Watts)
In general, if your 3000 Watt inverter is going to run on a 24V battery bank, you’ll need a 175-225 Amp fuse or circuit breaker. If the battery bank is rated at 48V, you’ll need a 90-110 Amp fuse or circuit breaker. However, the amp rating of the fuse or circuit breaker that you use should be greater than the ampacity of the wires.
In general, if the 3000 Watt inverter is going to run on a 24V battery bank, you should use 4/0 AWG copper wires. If the battery bank is rated at 48V, you should use 1/0 AWG copper wires with your inverter. To properly size the wires, you can use this Inverter wire gauge calculator.
