An inverter is a device that converts battery power (DC) into alternating current (AC) of a higher voltage. This means that most inverters are installed and used in conjunction with a battery bank of some sort – a common set up in off-grid solar installations. In general, you can expect your inverter battery to last anywhere around 5 to 10 hours when it is fully charged. However, you can easily calculate the accurate battery backup time with a simple formula or use a battery backup calculator.

An inverter is energy saving technology that eliminates wasted operation in air conditioners by efficiently controlling motor speed. Air conditioners maintain set temperature by cooling when room temperature rises above the set temperature and heating when the room temperature falls below the set temperature.
