Power consumption of a household electric inverter?

Archived in the category: cut your electric bill

I need to cut my electric bill badly.Do household inverters consume a lot of electricity while being charged continously?
Inverters are like generators.They charge when there is regular power supply.In case there is a power failure, it works just like a generator and supplies electricity for the entire house.My question was, if they consume a lot of power to charge up.Thanks

I think you mean UPS, Uninterruptible Power Supply. An inverter is part of a UPS, but only a part.

Inverters don't have batteries, don't charge, don't work where there is a power failure. All they do is convert 12v (or 24v) DC to 120 vAC.

Use of a UPS will only increase your electric usage, it can't possibly cut it. There is always a net loss when using a UPS. You use say 1000 watt-hours to charge it and you get out 800 watt-hours.

And in the standby mode they also use power, perhaps 10%, so if you draw out 1000 watts, they consume 1100 watts.

A UPS to run your entire house would be large and expensive. And don't forget you need to replace the batteries every year or so.

Huh????. Please explain.
Otherwise scissors will probably cut it up OK.
Are you talking about “inverter” air conditioners or something?
