1. Determine the load type (e.g., conventional load, inductive load, or mixed load).
2. Calculate the rated power of all load devices. For inductive loads, the maximum instantaneous load power needs to be calculated.
3. Determine whether it is a primary or backup power source. Primary power sources require a larger power margin.
4. Calculate the required total KVA value based on a power factor of 0.8.
5. Once the required voltage and frequency are determined, immediately select the correct generator set power.

Generally, Kohler generator sets under 30kW are sufficient for household use. Residential Kohler generators primarily power everyday household appliances, operating with relatively stable voltage and low loads. They are typically used as backup power, with a power margin usually increased by 10%.
Industrial Kohler generator sets have a wide power range, from 50kW to 2000kW. They experience greater load fluctuations, operating as both primary and backup power, and may encounter harsh operating environments. Therefore, industrial Kohler generators typically require a larger power margin, 20% or 30%.

The rated power output of a Kohler generator at 60Hz is typically 15%-20% higher than at 50Hz, and the voltage is also higher.
For example, if the 50Hz output is 400V, the 60Hz output can usually reach 480V.
However, Kohler generator sets at 50Hz have lower speeds, resulting in less noise and less engine wear, making them more suitable as primary power sources.
At 60Hz, the higher speed and greater power output lead to faster engine wear, making them more suitable as backup power sources.
Furthermore, requirements vary by country and region; for example, North America typically uses 60Hz, while Europe, the Middle East, and Africa usually use 50Hz.

The power selection is significantly different. Incorrect selection will shorten the lifespan of the Kohler generator set.
When your Kohler generator set is used as the primary power source, it is recommended to maintain 70-80% load and perform regular maintenance. It can typically last for about 20 years.
When your Kohler generator set is used as a backup power source, you can use it at 100% load. It can typically last 20-25 years. However, it is important to note that it should be turned on at least once a month and run at no-load for at least 30 minutes. Even when not in use, regular maintenance is still necessary.

Kohler generator sets have parallel operation control capabilities.
If you need to parallel operate them, we recommend prioritizing generator sets of the same brand and series.
Additionally, all generator sets paralleled should have similar power outputs to maximize consistency.
Using generator sets from different brands may lead to malfunctions due to differences in control systems.
Using generator sets with significantly different power outputs may result in malfunctions due to uneven load distribution.

Your high-power Kohler generator set may be operating under very complex conditions.
In this case, you can’t just look at the rated power.
You need to determine the generator’s operating mode (primary or standby), the required voltage and frequency (modifications later are complex, so it’s recommended to set them correctly before operation), whether parallel operation is needed, etc.
Most importantly, the load structure should be as simple as possible. If the load structure is complex, the requirements for the generator set and control system will be higher.

When a load starts, it generates a momentary high current.
Kohler generator sets’ excitation and control systems can respond quickly, stabilizing the voltage and restoring the frequency in a very short time.
This makes them particularly suitable for loads with large starting impacts, such as water pumps, motors, and compressors. Kohler generator sets have a relatively strong starting load capacity.

The operating environment for generator sets at sea is harsh, characterized by humidity and corrosion.
However, if the custom design and configuration are appropriate, the performance is not significantly different from onshore applications. Firstly, offshore generator applications are characterized by large load fluctuations, requiring long-term continuous operation, and frequent start-ups and shutdowns.
In such cases, a larger power margin is needed, ideally 30-40%.
Due to the harsh environment, rust-proof and corrosion-resistant coatings should be applied, and stainless steel fasteners should be used.

When using Kohler generator sets in remote areas, maintenance and spare parts are inconvenient. Avoid incorrect operation and overloading.
If the fuel quality is poor, a multi-stage fuel filtration system should be installed.
Determine whether the air filter system needs upgrading based on the generator set’s operating environment.
Add starting accessories adapted to high or low temperatures, and appropriately increase the power margin to avoid overloading.
Prepare maintenance materials (engine oil, oil filter, diesel filter, air filter, etc.) in advance and perform regular maintenance.

1. It is recommended that you install your Kohler generator set outdoors, maintaining a distance of at least 1 meter from the house.
2. It is recommended that you fix it to a hard surface or use a high-quality base.
3. It is recommended that you configure an ATS (Automatic Start-up System) so that your Kohler generator can automatically start supplying power after a power outage.
4. It is recommended that you add a soundproof enclosure to your generator set to avoid excessive noise affecting you.
5. Your Kohler generator must be grounded, and it is recommended to add a rain cover.

Your Kohler generator set will encounter various operating environments such as dust, high temperatures, mud, rain, and snow when working outdoors.
If you choose the appropriate power and configuration, long-term power supply is not a problem.
Generally speaking, outdoor construction places higher demands on generator sets than residential, industrial, and commercial applications, and Kohler generator sets operate stably under load fluctuations and harsh operating environments.

They can be combined very well. This high-efficiency hybrid power supply of generator sets and energy storage is a preferred choice for many power solutions, such as data centers, hospitals, and industrial parks.
When Kohler generator sets are combined with UPS systems, an ATS (Automatic Power Supply) system is required. During a power outage, the UPS takes over the load, and once the generator starts, the generator set takes over the load. This is particularly suitable for equipment that cannot tolerate power interruptions.
When Kohler generator sets are combined with solar power or energy storage systems, the photovoltaic power generation or energy storage system serves as the primary power source, while the generator set acts as a backup power source or for charging, effectively reducing power supply costs.

1. Your new generator set should undergo its first maintenance approximately 50 hours after purchase. This includes changing the engine oil and oil filter, and inspecting the overall condition of the generator set.
2. After the first maintenance, maintenance is required every 300 hours or 6 months, primarily involving changing the engine oil, oil filter, and diesel filter.
3. Every 500 hours or 12 months, check the air filter for replacement needs and inspect the fuel injection system and the overall condition of the generator set.
4. Every 1000 hours or 24 months, replace the air filter, check the coolant level, and perform a comprehensive inspection of the Kohler generator set.
5. Every 10,000 hours, a thorough inspection and maintenance of the engine valve clearances, fuel injectors, crankshaft, cylinder liners, pistons, etc., is required.

Typically, after a power outage, the ATS of a Kohler generator set automatically recognizes the problem in about 1 second, then the generator set starts.
The engine starts and begins to accelerate in about 3-5 seconds, and the voltage/frequency reaches its rated value and stabilizes in 3-5 seconds.
The load is usually connected in 1-3 seconds, and the total power restoration time is approximately 8-15 seconds.
Overall, the ATS switching speed of Kohler generator sets is quite fast.

If your generator set operates in low-temperature environments (-20°C to -55°C), you will need to install an oil heater, cylinder block heater, low-temperature resistant battery, and low-temperature resistant coolant.
If your generator set is used in an environment with humidity >90% RH, the engine set needs to be coated with an anti-corrosion coating, a high-protection-level generator should be used, and a soundproof enclosure should be added.
If your generator set is used in a high-dust environment, you will need to upgrade the air filter, install a multi-stage air filter system, use a large fan, and prevent radiator blockage.
Overall, with proper configuration, Kohler generator sets can operate stably in harsh environments.

Based on customer feedback and statistics, Kohler’s silent generator sets typically have a noise level of only 65 dB at a distance of 7 meters, small open-rack generator sets have a noise level of approximately 75 dB at 7 meters, medium open-rack generator sets have a noise level of approximately 85 dB at 7 meters, and large open-rack generator sets have a noise level of approximately 100 dB at 7 meters. Compared to other brands, this noise level is good.

Kohler generator sets are of high quality and should not have any problems under normal use. Problems are generally caused by operational issues such as incorrect configuration, improper load, or inadequate maintenance.
1. Reduced power and black smoke: This may be due to a clogged air filter.
2. High water temperature: This may be due to continuous overloading of the generator set or a clogged radiator.
3. Difficulty starting and unstable, fluctuating speed: This may be due to poor fuel quality or water ingress into the fuel tank.
4. Insufficient power and high fuel consumption: This may be due to generator set overheating or turbocharger wear.
5. Unusual noises and excessive vibration: This may be due to loose fastening screws.
6. Insufficient voltage and difficulty starting: This may be because the battery needs charging or replacement.
