Inverters do consume more electricity, if you’re thinking how much, just more than what it takes to charge it and use it. Usually, an inverter does consume more electricity when you are experiencing regular downtime and the inverter takes the charge of powering your house. More downtime is more use of inverter, so the more electricity consumption.
What kind of additional electricity used by inverters?
Inverters are not 100% efficient, they are just 80% efficient, this is the reason why companies offer the majority of the inverters in VA rating instead of clearcut kW. However, industrial inverters and high-capacity inverters are.
Even inverter’s battery banks are the biggest reason why your electricity bills are jumping. Most of us choose or get lead-acid batteries which itself requires regular maintenance and water top-ups. A lead-acid battery can not hold power for a long time, even if you do not use it, the battery will discharge slowly. The discharge rate may get higher once the temperature is too cool or hot, so decide a suitable area to install all this.
Rest is lost in AC-DC and DC-AC conversion.
You’ll able to use max of 60% to 80% of what capacity is installed.
So, to be honest, YES, inverter does consume more electricity than what you practically use. If you are planning to buy a new system make sure you get a highly efficient systems or get a bigger system than load.
