Generator General Questions

1. What is an Inverter Generator?

Inverter generators output produce a pure, clean AC sine wave.HEOMAITO inverters AC measure at less than 3% THD. That is more stable than most power companies can achieve on a mass scale.

Inverter generators also run quieter with the same load, longer on the same amount of fuel, and power direct AC circuit boards in sensitive items without worry.

2. What is the THD for our generators?

All HEOMAITO inverter generator's THD values are less than 3%. The inverter generator will output an industry standard total harmonic distortion (THD) rating of about 12%-20% depending on load applied. They will produce a sine wave, not a modified or square wave. If you have a specific item that requires less than 3% THD, we recommend purchasing a HEOMAITO Inverter Generator that provides a less than 3% THD.

DO NOT run HEOMAITO generator inside homes, garages, basements, crawlspaces, sheds, or other partially enclosed spaces, even when using fans or opening doors and windows for ventilation. All HEOMAITO generators come with Automatic CO Protection-With CO Alert technology, you can help protect you and your family by automatically shutting down your generator if unsafe levels of carbon monoxide are detected.

2. How does high altitude affect generator operation, and what measures can HEOMAITO provide to address potential issues?

High altitude conditions may lead to challenges such as hard starting, increased fuel consumption, and spark plug fouling. To address high-altitude operation, HEOMAITO can provide a high-altitude carburetor main jet. Information on the alternative main jet and installation instructions can be obtained by contacting Customer Support.

3. What are the temperature ranges for operation of HEOMAITO generator?

This product is designed and rated for continuous operation at ambient temperatures up to 104°F (40°C). It can be operated at temperatures ranging from 5°F (15°C) to 122°F (50°C) for short periods. Factors such as fuel BTU content, ambient temperature, altitude, and engine conditions can affect the maximum wattage and current. Maximum power decreases about 3.5% for each 1,000 feet above sea level and about 1% for each 10°F (6°C) above 60°F (16°C) ambient temperature.

4. What safety measures should be taken when handling the generator's gasoline?

Step 1: Turn off the generator engine and allow it to cool for at least 2 minutes before removing the gasoline cap. Loosen the cap slowly to relieve pressure in the gasoline tank.

Step 2: Only fill or drain the gasoline tank outdoors in a well-ventilated area.

Step 31: Do not overfill the gasoline tank. Leave space for fuel expansion.

Step 4: If gasoline spills, wipe the spilled gasoline from the unit or wait until it evaporates before starting the engine.

Step 5: Keep fuel away from sparks, open flames, pilot lights, heat, and other ignition sources.

Step 6: Regularly check fuel lines, tank, cap, and fittings for cracks or leaks. Replace if necessary.

Step 7: Do not light a cigarette or smoke.

Step 8: Do not pump gasoline directly into the generator at the gas station. Use an approved container to transfer the gasoline to the generator.

5. How do I connect the generator to my home?

Most of HEOMAITO generator models are compatible with an interlock kit, interlink, or 2 pole manual transfer switch. Inverter generators will require 3 pole transfer switch. Please see a local certified electrician for the best transfer switch option for your needs.

6. What steps can I take to reduce the noise of my generator?

HEOMAITO prioritizes noise reduction in its generator design, focusing on characteristics such as being lightweight, portable, and producing low noise levels. Our generators feature oversized mufflers that effectively minimize noise output. We advise against using third-party muffler silencers for noise reduction, as such modifications may void the warranty and contravene emission regulations.
