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. .<br><b>References : </b><br> I think you mean UPS, Uninterruptible Power Supply. An inverter is part of a UPS, but only a part.

Please explain. Otherwise scissors will probably cut it up OK. Are you talking about "inverter" air conditioners or something?<br><b>References : </b><br> Huh????. Please explain.
