- Difference Between UPS & Inverter?
Uninterrupted power supply (UPS) and inverter are both the devices used to support power supplies when the power outage happens. Is UPS the same as inverter? Which one is better for home/business use? Do I need a UPS or an inverter? If you have these questions, this video will offer you some help on understanding UPS vs inverter.
What is an Inverter?
An inverter, or a power inverter, is a power electronic device that converts direct current (DC) to alternating current (AC). It can be used as either a standalone device capable of receiving power from DC sources such as solar power and battery, and converting it to AC supply, or a utility-interactive inverter being one part of a bigger circuit such as power supply unit or UPS. An inverter does not generate or store power, but it can be connected to power sources, generally, batteries, to support power supplies.
And Now What Is UPS?
UPS refers to the uninterrupted power supply.
