How many batteries do I need for a 3000W inverter?
For a 12V 3000W inverter: You will need at least batteries with a total capacity of 1250 Ah 12V, or 15 kWh. For a 24V 3000W inverter: You will need at least batteries with a total capacity of 625 Ah 24V. For a 48V 3000W inverter: You will need at least batteries with a total capacity of 313 Ah 48V.
What voltage should a 12V inverter run on?
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?
What size wire do I need for a 3000 watt inverter?
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.
How much AWG wire do I need for a 12V inverter?
That's not 4AWG, that's 4/0 (0000) AWG. HUGE difference, literally. You want 4/0AWG wire for a 3000W 12V inverter. That is needed for all battery connections and wires to/from the inverter's battery connections. And you'll need a 350A fuse at the battery. As for your loads and proposed battery, a 12V 200Ah battery is 2560Wh.
