I want to ask that is impedance matching is needed between 24v to 220v modified square wave inverter at 50 Hz and a load e.g fan ??
If yes how to do that?
I have problem that whenever i attach a fan to my inverter the voltage drops from 220 to around 140 volts and fan runs slowly.
 

Hi,
This is not caused by the impedance unmatching, as you said the inverter working at 50Hz. Here it seems that the LOAD (FAN + OTHERS) is more than the INVERTER capacity. You did not define the INVERTER CAPACITY and the FAN LOAD.

Thanks for reply
now problem is that one fan (60W) is working almost fine but when i attach another same fan(60W) both runs very slowly.
Inverter wattage is 200W so more than both fans.
 

Hi Waqas,
sorry for such a long delay caused by my health being a Heart Patient. Anyways if the problem solved fine else please contact or post here.
