Inverter current is the electric current drawn by an inverter to supply power to connected loads. The current depends on the power output required by the load, the input voltage to the inverter, and the power factor of the load. The inverter draws current from a DC source to produce AC power.
The current draw of a 3000 watt inverter depends on the battery bank voltage. If the battery bank is rated at 24V, the inverter can draw up to 175 Amps. For a 48V battery bank, the amp draw will not exceed 90 Amps. This is assuming the DC-to-AC conversion efficiency of the inverter is around 85%.
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.
The inverter system also has some charging system that charges the battery during utility power. During utility power, the battery of the inverter is charged and at the same time power is supplied to the loads in the house. When utility power fails, the battery system begins to supply power via the inverter to the loads in the home as shown below:
A 3 kW inverter can deliver up to 3 kW of power as a maximum output. The actual current draw depends on the load power you are taking.
Higher input voltages result in lower current draw for the same power output, and vice versa. Inverter current, I (A) in amperes is calculated by dividing the inverter power, P i (W) in watts by the product of input voltage, V i (V) in volts and power factor, PF.
