In recent years, natural gas generators have become more and more common. In the past, they have been avoided due to lack of technology. They were not able to burn fuel as well, were not as durable, and technology did not exist to burn the gaseous fuels sustainably.
The concept of natural gas generators is exactly the same as those that run on gasoline. They are still powered by internal combustion engines but mix natural gas with air instead of gasoline. It is commonly found that natural gas generators are also able to run on propane gas.
Generac 7043 Home Standby GeneratorThe Generac 7043 is a standby generator with 22 kW of power. Being dual fuel, it can be fuelled by either natural gas or propane gas.
It has a large power reserve and great runtime capabilities. Due to these factors, it’s great as a standby or backup generator for your residence.
At peak power it will return 22,000 watts of power if it’s running on propane, and a very large wattage of 19,500 watts if it’s running on natural gas.
The 7043 has a remote monitoring system that means you can look at the statistics of your natural gas generator from any device that is connected to the internet. This gives you pretty much all of the stats that you could ever need to know about your 7043, including a fuel gauge, how much runtime is left, as well as how much power is being outputted.
Within the 7043 is one of Generac’s G-Force engines. The pressure lubrication that the engine takes advantage of means less maintenance and more reliability.
The 7043 natural gas generator comes with a display that can be displayed in many different languages that displays various points of information on the generator, including how much power you’ve got left, and reminders of service and maintenance intervals to ensure that your Generac is kept in the best shape possible.
The 7043 is a very powerful generator, but, it’s not an unreliable and unstable output – it’s fitted with inverter technology, making the power that it outputs safe for all appliances.
- Maximum peak power of 22,000 watts
- Dual Fuel – the 7043 can run on either propane or natural gas
- Highly reliable pressure-lubricated engine
- Outputs high-quality power with minimal harmonic distortion
- Maintenance required fairly frequently
- Wiring can be tricky to reach should you need to
Briggs & Stratton 20,000 Watt Standby Natural Gas/Propane GeneratorThis 20,000-watt generator from Briggs & Stratton makes use of their symphony power system in order to generate the best possible amount and quality of power. At 20kW of power, the unit uses the symphony power system to prioritize those appliances which are most important. It’s designed to use the power that it’s able to generate as well as possible – if there are too many appliances requesting too much power at the same time, it will detect this and split up the power between them or prioritize a few.
The symphony power system prevents the generator from long-term engine damage by overloading. It also means that the power that is output by the 20kW unit is safe for all types of appliance, no matter how large or small.
It’s able to run on your choice of propane gas or natural gas. If you’d like to use it as a reliable backup generator, Briggs & Stratton have thought of this too and installed a transfer switch. It detects when power is lost from your home and starts generating power for a smooth transition and minimal downtime.
Before the transfer takes place, even if your home is using more power than that which the generator can output at one time, the computer built into the unit will detect this and split up its power accordingly.
It’s got a massive power output of 20,000 watts when running on liquid propane (LPG), and is able to output 18,000 watts of clean power from propane gas too. It’s also supplied with a 5-year warranty from Briggs & Stratton.
It’s a quiet and refined natural gas generator, being able to operate at just 68 decibels. For reference, this is quieter than some conversations between humans. It’s the 993cc engine is powerful, efficient, and quiet. Even if the areas that you live in doesn’t have a high natural gas pressure, it’s still able to be used as it’s rated to be used in areas such as these.
If your home is a bit tight for space, this is a good generator to choose since it can be legally placed just 18 inches from the outer wall of your home
- Runs on natural gas or propane gas
- 20,000 watts peak power output from gasoline
- 18,000 watts peak power output from natural gas
- Reliable – this unit’s got a strong and durable Vanguard engine
- Safe – the unit is so safe that it can be placed just 18 inches from the outer wall of your house. The National Fire Protection Agency has verified this
- Durable – the casing that this Briggs & Stratton is in is designed to act against rust and harsh weather
- Quiet – this 20kW generator operates at only 68 decibels
- Automatic transfer – if being used as a backup generator, it can be automatically set up to detect when a power loss in the home happens. Downtime is therefore very minimal.
- Very large and not easy to install – with generators of this size, it’s advisable to ask a professional to install it
- Power transfer switch can be hard to get up and running
Kohler 20RESCL-200SELS Air-Cooled Standby Generator
The Kohler 20RESCL natural gas backup generator is extremely reliable as a source of refined backup that is both sustainable and efficient. It operates almost silently due to its advanced build quality and sound-proofing system.
It runs at a very low volume and is one of the quietest generators avaialble, being capable of providing up to 20kW of high-quality power when running on propane. The 20RESCL will still output a massive 18,000 watts of power when burning natural gas.
The 20RESCl can be monitored remotely via an online system. From any device that’s connected to the generator, you can choose to receive status information points on the generator such as the oil level, amount of fuel remaining, as well as how much power is being output.
You can use any amount of the power that the 20RESCL can output. It’s designed to prioritize certain appliances that are considered to be the most essential. If the 7043 starts to get placed under too much load, it will use this technology to power only those certain appliances. The prioritization system in the 20RESCL is very advanced indeed.
- Maximum Power Output: 20,000 watts
- Quiet and Refined
- Remote monitoring available
- Hard-wearing defensive enclosure
- High-quality power due to the 20RESCL’s inverter
- Customer service has been said it could be improved
