What are the Important Parameters of an Inverter?
What are the Important Parameters of an Inverter? Inversion, as a key power conversion process, is about efficiently converting direct current (DC) into alternating current
Aside from the operating voltage range, another main parameter is the start-up voltage. It is the lowest acceptable voltage that is needed for the inverter to kick on. Each inverter has a minimum input voltage value that cannot trigger the inverter to operate if the PV voltage is lower than what is listed in the specification sheet.
The inverter does not produce any power; the power is provided by the DC source. Figure below shows Basic DC-AC Inverter Block Diagram. A typical power inverter device or circuit requires a relatively stable DC power source capable of supplying enough current for the intended power demands of the system.
Some or all of the specifications usually appear on the inverter data sheet. Maximum AC output power This is the maximum power the inverter can supply to a load on a steady basis at a specified output voltage. The value is expressed in watts or kilowatts. Peak output power
It's important to note what this means: In order for an inverter to put out the rated amount of power, it will need to have a power input that exceeds the output. For example, an inverter with a rated output power of 5,000 W and a peak efficiency of 95% requires an input power of 5,263 W to operate at full power.
