How many 12V batteries do I need for a 3000 watt inverter?
The number of 12V batteries you need to power a 3000 watt inverter will depend on the amp-hour rating of the batteries. The amp-hour rating and the voltage of the battery determine the amount of energy (Wh) that the battery can store (which is calculated by multiplying the voltage with the amp-hour rating).
Generally, the larger the amp-hour rating and the higher the voltage, the more energy the battery can store.
Assuming the batteries you are using have a 12V amp-hour rating of 100, you would need 30 batteries for a 3000 watt inverter. This is calculated by dividing the amount of wattage (3000 watt) by the voltage (12V) to get the amount of amp-hours required.
This comes to 250 amp-hours (3000/12 = 250). Since each battery has an amp-hour rating of 100, you need 30 batteries to meet the required 250 amp-hours (100 x 30 = 3000).
It is important to note that this is the minimum amount of batteries needed to power a 3000 watt inverter. For best results, we recommend that you have a few extra batteries on hand to ensure there is no power failure.
