It is generally recommended that the total load does not exceed 80% of the maximum power of the inverter.

  • Consider starting power: Some appliances, such as small refrigerators or fans, will briefly require higher power when they start than they would during normal operation. Ensure that the inverter can withstand the instantaneous start power.

2. Select the output waveform

  • Pure sine Wave Inverter: If your equipment includes medical equipment, high-end audio equipment, or any equipment that is sensitive to power quality, it is recommended to choose a pure sine wave inverter because it provides power quality similar to the grid and is more secure for the equipment.
  • Modified sine wave inverters: For less sensitive appliances, such as simple chargers or lamps, choosing a lower-cost modified sine wave inverter is usually sufficient.

3. Input voltage compatibility

  • Make sure the inverter’s input voltage matches your DC power supply (such as car batteries, solar panels, etc.). Most 250-watt inverters are designed for 12V DC input, but there are also models designed for 24V or other voltages.

4. Port type and number

  • Select the appropriate output port according to the type of device you need to power, such as a standard AC socket, USB port, etc. Make sure the inverter provides enough ports to meet your needs.

5. Security features

  • Choose inverters with overload protection, overheat protection, short circuit protection, and low voltage warnings, safety features that protect the inverter and your equipment from damage.

6. Brand and quality

  • Choosing inverters with well-known brands and good user reviews can increase reliability and safety. Read user reviews and product reviews to learn about product performance and after-sales service.

7. Extra features

  • Consider whether the inverter needs additional features, such as remote switches, digital displays, network connectivity, etc., which can provide more convenience and monitoring options.
