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:
An inverter uses a small amount of energy during the conversion process. The difference between the input power and the output power is expressed in percentages. The efficiency of modern inverters is more than 92 %. This means that a maximum of 8 % of the power consumption is used to convert battery voltage to 230V/50Hz.
With home systems from batteries from 12V to 48V, the power inverter will always step up the voltage; thus, the current will be lower at the output of the inverter. With step up inverters, the wiring you use at the output of the inverter does not need to be as thick (or low of AWG) as the wires in the DC portion of the system.
Inverter battery usually comprises a battery bank and an inverter but may lack a built-in charger. It converts DC power from the batteries into AC power for household appliances when the main power supply is unavailable. Usage: Suitable for powering multiple home appliances, particularly in regions with frequent power outages.
