An inverter is a device that converts the direct current (DC) of the battery into alternating current (AC). How much AH battery is needed for the inverter depends on the usage time you expect. Regardless of the energy loss during the inverter process, if your inverter is 2000 watts and the battery output voltage is 12V, according to the formula P=UI, I=P/U can be obtained, and the battery output current is calculated to be 166.67A. Suppose your expected use time is t and the battery capacity is xAh, then x=166.67*t. However, in the actual use process, the circuit will be lost, and as the battery power decreases, the external output voltage U will decrease, and the output current will be greater than 166.67A. In other words, if you want to reach your expected use time, the battery capacity of the inverter should be greater than the result calculated by this algorithm.
