About 12v inverter wattage
A 12V inverter can typically support up to 1500 watts or 2000 watts, depending on the specific model. For example, a 1500W inverter running on a 12V battery can draw up to 175 amps of current1. Similarly, a 2000W inverter at maximum load will draw approximately 166.6 amps2.

6 FAQs about [12v inverter wattage]
How many Watts Does a 12 volt inverter use?
Things like camera and phone chargers are typically less than 50 Watts, and most laptops are under 100 Watts. So if we can restrict ourselves to those few things, a small efficient 150 Watt inverter will do just fine, and the current draw on the 12Volt side will be under 15 Amps – all quite manageable.
How many amps in a 48 volt inverter?
Now, maximum amp draw (in amps) = (1500 Watts ÷ Inverter’s Efficiency (%)) ÷ Lowest Battery Voltage (in Volts) = (1500 watts / 95% ) / 20 V = 78.9 amps. B. 100% Efficiency In this case, we will consider a 48 V battery bank, and the lowest battery voltage before cut-off is 40 volts. The maximum current is, = (1500 watts / 100% ) / 40 = 37.5 amps
How many amps does a 1200 watt inverter draw?
A 1200 watt inverter would draw 120 (60) Amps at full load. This is equivalent to the current drawn by a 1200 watt inverter at its load capacity.
How many amps does a 150 watt inverter draw?
A rough guesstimate of the 12Volt current drawn by an inverter is to take the wattage and divide by 10 – this is an easy one, just knock off a zero – so a 150 Watt inverter will draw up to 15 Amps . The far end of the scale is a 2000 Watt inverter, which is up there at 200 Amps!
How many amps does a 2000 watt inverter draw?
For a 2000w 12v pure sine wave inverter, the inverter amp draw depends on its watt load. The same inverter with a 1200 Watt load would draw 120 (60) Amps, which would be the same amount as a 1200 Watt inverter at load capacity.
How many watts can an inverter deliver?
Inverters come in all shapes and sizes – from small 150 Watt ones to those that will deliver 2000 Watts, and beyond. And then there are those that only claim they can deliver thousands of Watts. Yes, I’m afraid this is one area where we need to tread really carefully to make sure that we actually get what we think we’re getting.
