Generators running on natural gas and propane

Gas-powered generators have a terrible reputation for never running when needed and requiring constant maintenance. In this sense, a generator running on natural gas or propane is undoubtedly ideal for those looking for a reliable product with minimal supervision. Equipped with automatic transfer and operation systems, the generator is kept clean and always ready to operate. You can now count on a reliable and very low-maintenance generator.

The problem with gasoline generators

The main problem with gasoline generators is carburetor fouling. Gasoline which sits for more than a month in the carburetor and the tank degrades fouls the spark plugs and the carburetor. A catastrophic result. When you urgently need your generator, it won't start. Worse still, 40% of the generators in your area won't start either, and the only repairman available is overwhelmed with work for the next two weeks...
– In summer, you risk losing all the contents of your freezers and refrigerators.
– In winter, the house can freeze in less than 24 hours.
– In rural areas, you find yourself without water because the pump no longer works.
– The basement drain pump (sump pump) no longer works, and your basement is flooded.
– Then add all the activities of daily life disrupted by the lack of electricity.

A generator running on natural gas or propane eliminates all the disadvantages of gasoline generators.
An automatic maintenance start. A control mode allows the generator to be started automatically every month or according to another interval to keep it clean and operational.
A safe fuel. Unlike gasoline, propane is not degraded over time in its pressurized container.
Automatic management. An intuitive transfer panel manages the starting and stopping of the generator. Whether you are present or absent, your home will never run out of electricity, and it will remain a secure place.

Its mode of operation

Normal operation. In a normal situation where electricity is available, the electricity is routed to the transfer panel, which sends it to the main distribution panel of the house.

The standard distribution panel and electrical circuits are not affected by the addition of the automatic transfer panel. A battery charger is installed in the transfer panel to keep the generator starter battery charged.
In case of failure. When the electrical input voltage drops below 85% of its average voltage for more than 3 seconds, a start signal is sent to the generator. When the generator reaches the desired voltage, power transfer is achieved.

This sequence typically takes less than 10 seconds.The return of electricity. When power returns to the public transmission line for five minutes, the transfer panel returns to that source.

However, the generator will run at low speed for another 5 minutes (without being plugged into the house) to slowly cool down and return to standby mode

Automatic maintenance cycles

Choice of the cycle. It is possible to choose the time and the process of days of the automatic start, which will maintain the maintenance of the system. During its operation, the generator is not connected to the electrical network of the house, and the electricity coming from the public service is not interrupted.
Manual operation is possible. Those who prefer to carry out the preventive start manually can do so by positioning a switch in manual mode. The electricity will not be transferred to the house, and the public service will not be interrupted.
A manual test. It is also possible to manually simulate a service failure to ensure the device's proper functioning

At a reasonable price, propane-powered generators can meet most of the needs for homes, constructions, and RVs. Propane is inexpensive compared to gasoline and can be stored for a long time, so dual-fuel generators gasoline or propane are commonly used.

Starting capacity running time portability when using propane are factors for us to make a list of products for you to choose from; after reading many reviews and specifications of the machine, This will cost you a lot more time and effort to determine.

Why choose a generator running on propane?

Propane produces half the amount of carbon monoxide than gasoline does. It also requires less energy to power your home than natural gas. Fewer pollutants mean fewer carbon deposits in your generator's engine. That's another reason a propane generator requires less maintenance.

Compared to gasoline, propane is considerably inexpensive as a gas supply to energy your generator. Additionally, it is simpler for the retailer for lengthy intervals. In contrast, gasoline goes stale and may smash your carburetor after just a few months; propane will final for as much as a yr and gain injury to your generator since it isn't left contained in the generator's gas reservoir. This makes propane a terrific alternative if you're making ready for an emergency and don't need to need to repurchase a gas provided every few months.

What are your power needs?

How much energy your generator might want to present depends upon what home equipment you're planning to run off of it. Suppose you're planning to make use of your generator to energy your entire home in an emergency. In that case, you'll need to discover a high-powered generator that may output at the least 5,000 W and much more when you have a water pump or energy-hungry heating system. Then again, a smaller generator that places solely 3,000 W could be sufficient if you're attempting to energy an RV or a campsite. If you're planning to run your generator totally on propane, be sure to think about how a lot of the energy the generator you select can output on propane moderately than gasoline.

It would help if you had a generator with a long-running time of 10-12 hours; the generator's capacity must be doubled. 

If the generator run time is short, RV only or brief time of day, the generator capacity is not essential.

The output power of your generator can be considered in the runtime that you will get.

What to look for in a portable generator that runs on propane?

Beyond wattage, there are a number of convenience and safety features that differentiate portable generators from one another.

What are the pros and cons of a propane generator?

Extra eco-friendly than fuel. “Propane engines emit 12 % much less CO2 emissions, 20 % much less NOX emissions, and 60 % much less CO emissions than gasoline engines. ... Simpler to refuel. ... No expiration date. ... Much less noisy than fuel. ... Extra highly effective than fuel.

What is the most efficient propane generator?

The Westinghouse Outdoor Power Equipment WGen9500DF is a great all-round propane generator that is highly rated by many satisfied shoppers, but for a little (well, a lot) more power, we recommend the DuroMax XP13000HX that has 13,000 peak watts
