Enter the kWh (units) from your electricity bills to find your average load and get the right IPS, battery and solar recommendation.
Enter your electricity bill units (kWh) from each month:
You can find the kWh (units) on your monthly electricity bill. More months = more accurate.

Enter the kWh (units) from your electricity bills above to see your average load and get a recommendation.
If your last 3 bills were 210 kWh, 250 kWh, and 190 kWh:
For 2 hours backup: a 12V 110Ah battery + 500VA IPS + 600W solar would cover most of your needs.
❌ Using only one month's bill
A single summer month with AC running may show 400+ kWh, while winter months could be 150 kWh. Always average at least 2–3 months.
❌ Confusing bill amount with kWh
The bill total in ৳ is NOT the kWh. Look for the “Unit” or “kWh” number — that's what you need to enter.
❌ Forgetting seasonal variation
If you use AC in summer but not in winter, your average will be lower than peak. Consider adding a backup for your highest-use month.
Look for 'Unit' or 'kWh' on your monthly electricity bill from DESCO, DPDC, BREB, or your local utility. It's usually near the total amount.
One month's bill can vary (hot months use more AC). Three months gives a more accurate average of your real electricity consumption.
Yes — any electricity customer can use this. Just enter the kWh from the electricity bills for the location.
That's normal — seasonal changes, guests, or new appliances can cause variation. The calculator averages them out. Add more months for better accuracy.
It's a starting point. Real usage depends on appliance types, battery condition, and other factors. Use this as guidance, then verify with a professional.
