Things to Remember while Buying a Whole House Generator 

Power Output

This is the first and foremost factor you need to consider before choosing the generator since each has various power outputs. What electrical devices do you want to operate during a power failure? How much power is required for this? Based on the factor, you have to choose the generator. For large and mid-sized homes, go with high power output models and average levels for small to medium-sized homes.

Fuel Type

Of course! The fuel type of the generator is also essential. Usually, the whole house generators have included liquid propane and natural gas fuel types, but some only run either. This is why it is essential to pay attention to their fuel type before buying it.

Noise and Fumes

One thing to consider while buying a whole house generator is the noise level. How would the noise and fumes level be? You probably don't want to have a noisy generator since it might disturb you and your neighbors.

The industry standard of the generator is measured by standing 23 feet away from the generators. A 70-80 decibel sound is much like a vacuum cleaner which is the average noise for a generator. This unit has a 74-decibel noise level which is pretty good for a portable generator.

If you think this is too much noise, you can use a muffler or silencer to reduce the noise level. This should be another consideration if you are concerned about it. Mostly, the whole house generators noise would be higher than inverter or portable generators, but not too much level.

Engine

The Kohler 20KW generator is powered by Kohler's Command Pro CH1000 air-cooled engine, which comes with hydraulic lifters. The 999 cc V-Twin lets you operate at a maximum of 32 horsepower. So, you can easily switch to the unit at 3600 rpm on overload conditions. It uses a fully pressurized oil lubrication system, which holds an integrated oil cooling unit and three quarts of oil. Both these offers unattended and extended run times. When it comes to the maintenance of the engine, you can schedule for oil and oil filter changes 150 hours of run time or annually, while air filters and sparks plugs need to be changed 300 hours or annually.

Transfer Switch

This unit has RTX 200 amp transfer switch, which can directly work with the DC2 controller on the generator's board. It keeps monitor the utility of the electric current and sends the actual data to the controller.

When it detects some interruption or falls below acceptable levels in the electric current, it helps start the engine immediately right after a short outage. First, the engine starts to reach optimal speed, and the transfer switch helps the generator power to the home power sources.

After the electrical power is restored, all the home sources are moved onto the utility power. So the generator gets shut down automatically after cool down the engine. The RTX 200 amp is installed with the load shed kit, which monitors the current and frequency of the generator to determine when to shed loads.

Controller

The RDC2 controller works with the transfer switch and delivers the power for various appliances during a power outage. It comes with four-button operator interfaces with LED indicators and an LCD display. This lets you know the different status of the generator, including maintenance reminders, voltage and frequency, etc.

On display, you can find the transfer switch, alternator, load control module, programmable interface module, and diagnostic messages for the engine. It also features an Ethernet port for controlling and monitoring the generator.
