# What size power inverter do I need?

The size power inverter you need depends on the wattage requirements of the devices you intend to power. To determine the wattage requirements for your devices, you will need to look at the manufacturer’s spec sheet or labeling on the device itself.

Once you have the wattage requirements for all the devices you intend to power, add up the total wattage. For example, if you have 3 devices that require 500 watts, 300 watts and 200 watts respectively, the total wattage you need is 1000 watts.

In this case, you will need a 1000 watt power inverter. It is important to choose a power inverter that is at least as powerful as your total wattage requirement. If you choose a power inverter that is too small, you may risk damaging your devices or drawing too much power and overheating your power inverter.

For safety, it is generally recommended to choose an inverter that provides 5% more wattage than your total wattage consumption.

## How do I calculate what size inverter I need?

Calculating the size of inverter you need is an important step in selecting the inverter that is most suitable for your purposes. The size of inverter you need depends on the amount of watts you plan to use and the voltage you’ll be using for the application.

To start, you should list all the devices you plan to have connected to the inverter and determine their power requirements (listed in watts) and their voltage requirements. Once you have the total wattage and voltage requirements of all the devices, you can use this formula to calculate the inverter size that would be most suitable: Watts x 1.

25 = DC Amps and Volts x DC Amps = Watts = Size of Inverter. For example, if you need 400 watts at 12 volts, then you would need a 400 Watt inverter (400 x 1. 25 = 500 Amps and 12 x 500 = 6000 Watts).

Furthermore, to ensure the inverter you select is right for your application, consider the starting and surge power requirements of the devices you plan to run with the inverter, as higher power demands could require a larger, more robust inverter than the wattage formula alone would suggest.
