Going to purchase an inverter but unsure about the wattage that you should opt for? Believe me, you are not alone in this struggle because when it comes to electronics everyone gets confused. Understanding amperage and wattage is crucial for its effective operation. So, in this blog, we will learn how many amps a 2000 watt inverter draws and also find the same for different wattages such as 200W, 300W, 500W, 750W, and 1000W.
How Many Amps Does A 2000 Watt Inverter Draw?
The power inverters have a voltage range between 12V and 120V. The maximum amps (current) drawn by a 2000 watts inverter depends on its conversion efficiency and voltage rating of the battery bank.
A 2000-watt power inverter running on a battery bank of 12V would draw around 240 amps and with a 24V battery bank, 120 amps could be drawn. However, a battery bank with a 48V would not exceed 60 amps. Here, the lowest battery voltage (before cut off) is 10 volts for 12V, 20 volts for 24V, and 40 volts for 48V battery bank.
You can use the following formula to calculate the number of amps drawn by your 2000 Watts inverter.
Maximum current drawn (Amps) = (2000 watts/inverter efficiency in %)/lowest battery voltage (V)
Your inverter of 2000 watts and 12V with a 90% efficiency claimed by the manufacturer the amps drawn would be.
= (2000 watts / 90%) / 10 V = (2000 watts/0.9) /10 V = 222.2 amps.

How Many Amps 200W, 300W, 500W, 750W and 1000W Inverters can Draw?
Using the above formula, we can find the amps at 12V ( 10 V cut off voltage) for 200W, 300W, 500W, 750W and 1000W inverters considering 100% and 85% efficiency.
| Wattages | Voltage | Amps drawn for 100% Efficiency | Amps drawn for 85% Efficiency |
| 200 W | 12 V | 20 A | 23.53 A |
| 300 W | 12 V | 30 A | 35.29 A |
| 500 W | 12 V | 50 A | 58.82 A |
| 750 Watts | 12 V | 75 A | 88.2 A |
| 1000 Watts | 12 V | 100 A | 117.6 A |
Must Read: How many Amps Does a 1500 Watt Heater Draw?
How Many Amps 1500W, 3000W, 4000W and 5000W Inverters can Draw?
Using the same formula, below are the amp ratings at 24V (with 20V cut off voltage) for 1500W, 3000W, 4000W and 5000W inverters considering both 100% and 85% efficiency levels:
| Wattages | Voltage | Amps drawn for 100% Efficiency | Amps drawn for 85% Efficiency |
| 1500 W | 24 V | 75 | 88.23 |
| 3000 W | 24 V | 150 | 176.47 |
| 4000 W | 24 V | 200 | 235.29 |
| 5000 W | 24 V | 250 | 294.11 |
Note: The data may vary due to various factors such as inverter models, efficiency, and power losses.
Well, today you learned how many amps a 2000 watt inverter draws. In this calculation, you have to consider the power bank voltage and the inverter efficiency. However, other factors like power usage and surge or continuous power supply are important parameters to count on. To learn more about inverters, check out the dedicated category.
