Question

This is the generator i bought.

https://www.mticanada.ca/catalogue/produit/185513/2000w-inverter-generator-dual-fuel-propane-and-gasoline/show

It works fine with the small bottle of propane hookup with the generator as ilustraded

When I hook up with my big 400 pounds propane tank it does not start.

The knob is at propane, we can smell the propane.

The connection with the big tank is thru a ball valve and quick connect 3/8 inch.

We use the regulator on the big tank and the supplier says it is 11 inH20.

The one supplied with the generator is not used.

All plumbing work was done by paid professional.

We test it with 2 identical generators. One made in 2019 and one made in 2022.

All appliances in the house are functional.

During the tests we did not use any appliances of the house.

All suppliers do not know and say it should work but it is not.

Answer 1

Based on the information provided, it seems that the issue may be related to the low pressure of propane supplied by the 400-pound propane tank. The supplier states that the regulator on the tank is set to 11 inH2O, which is likely the low pressure output for the tank. However, the propane regulator supplied with the generator is not being used.

The propane regulator supplied with the generator is designed to reduce the high pressure of the propane tank to the low pressure required by the generator, which is typically around 11 inH2O. If this regulator is not used, the propane pressure may be too high for the generator to function properly.

It is also possible that there is an issue with the connection between the propane tank and the generator, such as a leak or a blockage in the gas line.

To troubleshoot the issue, it may be helpful to check the following:

1. Ensure that the propane regulator supplied with the generator is installed and functioning properly.
2. Check for any leaks or blockages in the gas line between the propane tank and the generator.
3. Verify that the propane tank is not empty or nearly empty.
4. Contact the manufacturer or a professional technician for further assistance if the issue persists.

Additionally, it may be helpful to check the specifications of the propane tank to ensure that it is compatible with the generator. The generator you purchased is a dual-fuel model that can run on both propane and gasoline, but it may have specific requirements for the propane tank.

Some possible factors to consider include:

1. The propane tank should be equipped with a standard 3/8-inch female flare fitting to connect to the generator's regulator.
2. The propane tank should be compatible with the type of propane used (e.g., HD-5 propane).
3. The propane tank should be large enough to provide the necessary fuel supply for the generator to operate at its rated load.

If the propane tank meets these requirements and is functioning properly, but the generator is still not starting, it may be helpful to contact the manufacturer for further assistance or to have a professional technician inspect the generator and propane system.
