Does inverter increase electricity bill?

Inverter, Power Inverter, or Uninterrupted Power Supply (UPS) all are one and the same thing. Inverter is an electronic device that stores electricity in batteries to use it later when there is an outage. Inverters are useful when you live in a location with most power cuts and needed a 24×7 electricity supply.

If your monthly bills are making you worried then be clear here that it is common because you’re using the more electricity with inverters.


Let’s understand this scene through real-life examples.

Case #1: Fixed downtime everyday.

Assume you are getting around 20 hours of electricity from the grid supply. The total downtime will be 4 hours. In this case, your inverter will be backing up your home for those 4 hours of downtime and once there is a grid supply and it will charge back itself again.

Here you are absorbing that 4 hours of extra required energy from the grid to the inverter to charge itself for any further outages. So technically in this case, it will raise the electricity bill for that additional use.

Case #2: Uncommon downtime.

Let’s say you live in an urban area, where power losses aren’t common but an inverter is installed for any unexpected downtime. Assume once your inverter is charged fully, it is not going to discharge itself as no downtime simply means why would an inverter run. Suppose in a week there was a downtime of 4 hours, so the inverter will again follow case #1. But this time the case was not common. This is not a daily downtime, it’s once a week or less. Here you’ll see a negligible amount over your monthly bill.

Why is so? This is because batteries installed on inverter need a small amount of charge no matter whether you use it or not. This is to sustains the life of batteries which discharges by a very small percentage everyday when not used for any load.

Practically no one uses inverters where electricity supply is always available.

I think you are clear here about why do inverters raise your monthly electricity bills while being used or not. If you really want to save on electricity bill, look for solar it will be affordable.
