Fuel Consumption and Noise Output

WEN 3100-watt Inverter Generator ReviewThis generator runs on gasoline with an octane level of more than 87. It boasts a 1.85 gallons’ fuel tank capacity. Check the octane rating on the front label of the fuel container. This generator can achieve a runtime of about 7.5 hours when running at a half load. When comparing WEN 56310i runtime with other models, check on their runtime at 50% load. WEN 56310i offers one of the best fuel efficiency ratios in its power output range, thanks to its eco-mode feature. Even so, such a runtime will only allow you to power very few devices. If you need a higher runtime, you should consider another model with a bigger fuel tank and high fuel efficiency.

The noise output on this model is not of concern, provided it’s not running on a full load. While running on a low load, this inverter generator has a noise output of 57 to 58 decibels when running from 22 feet. At a full load, the generator gets noisy, producing around 68 decibels. However, you can reduce the noise output by placing it further than 22 feet or investing in a sound dampening box.

Start-up Option

This model only starts via the conventional recoil start mechanism. Before starting this generator, ensure;

  • The generator is not loaded
  • You are operating it in an open space
  • The eco-mode switch is in the OFF position
  • The 3-in-1 choke switch is in the CHOKE position and later switch it to ON when the engine is up and running.

The generator should easily start from your first or second pull.

Control Panel

WEN 3100-watt Inverter Generator ReviewWEN 56310i does not have an LCD but comes with an intuitive control panel with multiple functionalities. They include;

  • An eco-mode switch allows you to turn on the eco-mode feature for maximum efficiency, low fuel consumption, and low noise output.
  • Parallel connection ports: You can quickly link this generator to a similar model to double its power output. The parallel kit is sold separately.
  • 3-in-1 switch: This switch allows you to choke the generator, turn on the fuel valve and switch on the engine.
  • Three light indicators signal when the unit is running normally, overloaded, and when the oil level is deficient
  • Power outlets: You can connect different types of appliances on this model thanks to its multipurpose receptacles.
  • Grounding nut: You can ground your generator via this nut. However, you have to check with your local regulations before proceeding to ground the generator.
  • Press to reset buttons for resetting circuit breakers: Once the generator shuts down because of overloading, you can reset it by pressing these buttons.

Such functionalities make this generator easy to use. However, the labeling on the control panel is a disadvantage; the writings are too small, making it difficult for anyone with weak eyes to decipher.
