1. How long can I continuously run my standby generator?

Essentially, your standby generator will run for as long as you need it to provided there is enough fuel supplied to it. But, you should practice some precaution during extensive power outages that span several days and try to conserve your generator usage, especially if it’s running on diesel or LP. Diesel generators are available with 24-hour, 48-hour and 72-hour fuel tanks. Natural gas generators don’t require fuel tanks – a plus. And as a rule of thumb, you should occasionally be shutting your generator down to let the engine cool – especially during a longer power outage.

2. What type of service or maintenance will need to be performed?

There is certainly some maintenance you’ll want to keep up with to prolong the life of your generator. With that said, maintaining a natural gas engine is quite similar to that of a diesel engine.

On a day-to-day basis, try to keep your generator warm and dry and safe from pests, and be sure to regularly check fuel, oil and water levels. Ensure the generator’s electrical connections are intact (an electrician will be able to help with that). Keep components lubricated regularly. On a yearly basis, have a technician help you with oil and filter changes, as well as fuel and air filters, and spark plugs. Ensure you’re keeping your unit clean, and performing all necessary tests.

3. What type of fuel do I need?

It’s best to choose a generator that uses the type of fuel most convenient or appropriate for you. For example, if you have a natural gas or propane line that already runs to your location, this can be a good choice. On the other hand, gasoline is an ideal option for isolated areas, and tends to be more available than diesel fuel. You’ll need to ensure that you’ll be able to get fuel easily delivered to your location when you need it. Diesel engines are, on the other hand, known for being very reliable and efficient – but they are a hefty penny compared to the other engine types.

4. What type of transfer switch will I need?

After you’ve decided on a generator to power your farm, you’re going to need to decide on a transfer switch - either a manual or an automatic transfer switch. Installing a transfer switch helps to prevent back-feeding or overlap, and will provide you with fast, direct and efficient access to power in the event of a failure. (Note: you MUST get a qualified electrician to perform the installment; any inexperience can be fatal as you’re dealing with electricity, here!).

A manual transfer switch is standard and ideal for farmers with a PTO-driven unit (not to mention, a lot more friendly to the wallet). It will require manual start-up in the case of a power outage, and then must be manually switched back to the power provider once the power comes back on. A good thing about the manual transfer switch is that it’s easier to maintain and install compared to an automatic transfer switch.

A little more on the fancy side, an automatic transfer switch is convenient and great for generators compatible with auto-start systems, and is a more worthwhile investment for farmers living in areas that experience frequent outages. This type of transfer switch will know when the power fails and will automatically signal your generator to get to work. No action is required on your end, either once the power comes back on.

5. How long will my standby generator last?

Industries rely on various power systems, making it vital to understand generator voltage levels for compliance and efficiency

Generators are categorized into high, medium, and low voltage, each suited for specific applications—from powering large machinery to serving as backup for smaller businesses. Choosing the right voltage is essential for meeting standards and optimizing performance.

Different sectors, such as energy, manufacturing, and construction, have unique voltage requirements. Proper voltage usage enhances safety and operational efficiency, preventing malfunctions and overheating.

What is Generator Voltage?

Generator voltage refers to the level of electrical power produced by a generator, which is crucial for power generation and affects the compatibility and performance of electrical systems. Generators can be categorized based on their voltage output into high, medium, or low voltage, depending on the specific needs of different industries.

Low voltage generators produce 240 to 600 volts, making them suitable for powering sensitive electronics.

In contrast, medium voltage generators, which range from 1,000 to 35,000 volts, are typically used in applications that require substantial power. These include industrial facilities, large commercial buildings, data centers, healthcare facilities, refineries, petrochemical plants, steel mills, and other sectors that rely on reliable backup power.

High voltage generators produce 35,000V to 100,000V. They are used in power plants, utility grids, and industrial applications requiring large-scale energy generation. These generators help transmit electricity efficiently over long distances and power heavy machinery in manufacturing plants.

High Voltage Generators

High-voltage generators are used for large-scale industrial operations and infrastructure projects that require significant power output. They are integral to power generation and heavy manufacturing, helping equipment run efficiently in power plants, factories, and energy-intensive environments.

These generators are particularly beneficial for high-power applications because they enable more efficient electricity transmission over long distances when paired with step-up transformers. y operating at higher voltages, they reduce electrical losses, making them valuable assets for utility providers and heavy industries.

They also improve power transmission efficiency by operating at lower current levels. This reduces the size of conductors, lowers wiring costs, and minimizes heat loss, leading to better overall electrical efficiency.

Medium Voltage Generators

Medium-voltage generators balance high and low voltage, offering efficiency and versatility for industrial and commercial applications. They are particularly well-suited for industries such as mining, construction, manufacturing, and data centers, making them an excellent solution for operations that require reliable, moderate power output.

These generator sets offer unique advantages, including enhanced reliability and cost-effectiveness. They require smaller conductors compared to low-voltage systems, which reduces installation costs. Additionally, medium-voltage generator sets allow for more efficient power distribution throughout a large facility with fewer conductors.

Low Voltage Generators

Low voltage generators are ideal for smaller-scale applications, such as residential backup power, localized commercial use, and small industrial setups. They offer a safe and efficient power source for operations that require lower voltage levels, often supporting sensitive electronic devices and localized power grids.
