Does Inverter Consume More Power. Thus the compressor is always on. Several people have the misconception that the only work of an AC is to throw cool air.
The larger the higher the wattage rating the inverter the more idle power it generally consumes. Connecting too small a load to an inverter compared to its power rating reduces the overall efficiency of the inverter setup. Even at no load condition it consumes little electricity and that is why its efficiency is not 100 but slightly less.
You should run an inverter rated 2000W with a load of about 800W -1000W instead of running it with a load of 20W.
The difference between the input power and the output power is expressed in percentages. So it does consume little electricity even after full charge. Using an Inverter for Emergency Home Backup Power. In true online UPS when battery charges fully it is kept on trickle charge.
