Read! Inverter saves in this poor power supply and no-fuel situation

In a month I normally use fuel worth N8000 to power my generator anytime there's power outage but since I bought my inverter more than a year ago, I spend averagely N500 per month. Yes..N500 averagely as I
could go for 3months sometimes without putting on my gen. This backup system has been very helpful especially now that there is poor mains supply and fuel scarcity with exorbitant price. Those of you complaining of excessing estimated bill, you can get value for the bills you pay if you have a backup system since you'll massively utilize the mains when it is available provided you can have light at least once in two days.
Below is my 1.5kva sine wave inverter and 4batteries system.
Show us pics of your backup system and tell us how much you save from this arrangement per month.
