How efficient is an inverter?

Enerdrive inverters have a max efficiency of 90%. This means that the power required to run your inverter will be around 10% higher than the power load of the appliances you are running. For example, if your kettle is plugged into your inverter and consuming 1500W of power, then your inverter will be drawing about 1650W from your batteries.

Some of the power lost during the process of converting DC to AC power will be transferred into heat and cause your inverter to warm up while it is operating. The production of heat means that it is important to ensure your inverter is in a well ventilated area and that its air intake and exhaust fans are not obstructed.

Your inverter will also draw a small amount of power from your batteries in order to operate, even if it has no AC loads attached to it. For most Enerdrive inverters, this is <1.5A. Because of this small standby power consumption, it is best to turn your inverter off when it is not in use. For more information on standby power consumption, click here.
