You would need around 24v 150Ah Lithium or 24v 300Ah Lead-acid Battery to run a 3000-watt inverter for 1 hour at its full capacity Here's a battery size chart for any size inverter with 1 hour of load runtime Note! The input voltage of the inverter should match the battery voltage.
In this case, you need to make sure you have the right size AWG cables. The most common size cable for a 3000 watt inverter is 4/0 AWG. It is not a set rule as the gauge of wire changes depending on length. To be honest, 3000 Watt inverters are pretty big so you will need a minimum of 300Ah battery capacity in my experience.
Let's say you have a 300Ah battery. 300 ÷ 250 = 1.2 hours. Drawing 3000 watts from a 300Ah battery will run for a maximum of 1.2 hours. If you reduce your power draw to 2000 watts, you would increase your runtime to nearly 2 hours! Remember, a 3000W inverter won't always draw maximum power, it depends what appliances you are running.
To determine the required battery capacity for your 3000W inverter, you need to calculate the total energy consumption in watt-hours (Wh) per day and then divide it by the depth of discharge (DOD) of the battery, which is typically around 50% for deep cycle batteries to prolong their lifespan.
The input voltage of the inverter should match the battery voltage. (For example 12v battery for 12v inverter, 24v battery for 24v inverter and 48v battery for 48v inverter Summary What Will An Inverter Run & For How Long?
