Inverter & Power consumption

technofast

Huh?
Adept
I have a Microtek 1100VA inverter connected to a Exide Invared 500+ 150Ah battery. As I noted for the past couple of months the power consumption from this unit is around 7 units per day and roughly around 200 plus units per month. This is when the inverter is in standby mode and not charging (or maybe trickle charging). Whenever the inverter is charging after a power failure it adds up couple of more units to the perday unit. There is no power cut and the power goes off very rarely in my area. So mostly the inverter is in standby mode only throughout the month. Also I should mention that the battery is 7 years old but maintained good and still has decent backup for 4 hours or more depending upon the load. I am not sure if this power consumption is normal with any or all of the inverters with this capacity. I feel that the inverter alone is taking up too much of power consumption. Any solution to reduce the power consumption of the inverter? I do not want to invest on new battery or inverter now.
 
It's due to the transformer inside the inverter. The 1100 VA probably has a 550-850W transformer inside it which puts an active load on mains line 24/7. So you are seeing those 7 units per day usage. I removed my inverter because of this. The cost of inverter based power is too high for flat residents. If you have your own house/bungalow then you can install 3-5KW solar and connect the inverter to it.
