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:
Now to determine how much power your inverter is drawing without any load, multiply the battery voltage by the inverter no load current draw rating. For example, Battery voltage = 1000 watts Inverter = 24V No load current = 0.4 watts Power drawn = 24V * 0.4 = 9.6 watts
In some configurations, a standard inverter may consume between 0.416 amps and 2.83 amps of power in idle mode. But this amount may vary depending on the type of battery bank used and the types of loads connected to the inverter. Typically, in a no-load current, the energy drawn by the inverter is only 2 to 10 watts an hour.
The laptop will draw the same amount and the inverter capacity is really just that, capacity? i.e. 1000-watt inverter CAN draw UP TO 1000-watts, and the same for 500-watt inverter. My issue is that I plug in a 1000-watt inverter to a battery, and voltage is dropping to 12.2v.
Approximately, yes, they would consume the same amount of battery power. All else being equal. But some inverters are more efficient than others. And there are a lot of very poor quality inverters available on the market for some reason. Note that a 1000 Watt inverter would need to use around 100 Amps from the battery to produce a true 1000 Watts.
Inverters convert DC voltage to AC voltage. They have a battery system which provide adequate backup time to provide continuous power in the home. The inverter system then converts the battery voltage to AC voltage through electronic circuitry. The inverter system also has some charging system that charges the battery during utility power.
How To Charge Inverter Battery | Tips & Charging Time
Typically, an inverter may take anywhere from 6 to 12 hours to full charge a standard tubular battery. The key influencer here is the charger''s output capacity—higher capacities result in faster charging times. Conversely, UPS systems tend to charge more quickly due to their smaller battery sizes and efficient charging mechanisms.
