The Frontier Power—Kohler Advantages

Here are two reasons why you want to talk to us about your standby generator needs:

  1. Most of Kohler’s industrial generators are powered by either a John Deere or Mitsubishi engine. We are very familiar with these engines given that we are exclusive distributors of John Deere and Mitsubishi engines in Western Canada.
  2. Kohler selects from a wide selection of engines, including John Deere and Mitsubishi, to power their generators. Not being tied to one engine supplier allows us to deliver a generator with the best load response for your application.

Checklist of Things to Consider


Common single phase voltages in North America are 120/240. These voltages are often supplied by generator sets as they are frequently used in household type loads.

Common three phase voltages found in North America are 120/208, 277/480 and 347/600. (Measured – line-to-neutral/line-to-line).


Most of North America is 60 Hz or 60 cycles per second for AC power supply. It is not uncommon to have European or Asian equipment to power and this is usually 50 Hz. AC supply.

To produce 60 Hz power, engine driven generators will operate at 1800 rpm using a 4-pole generator. Lightweight, portable or residential generators may operate at 3600 rpm with a 2-pole generator. Larger generator sets may run at 1200 rpm (6-pole) or 900 rpm (8-pole) or 720 rpm (10 pole). (50 Hz is similar but 3,000 rpm for 2-pole, 1500 rpm for 4-pole, 1000 rpm for 6-pole etc.)


Residential and most light commercial services are single phase. Larger commercial and industrial services are normally three phase. Although there is no hard and fast rule, generators over about 50 kWe are usually three phase. On larger sets, if the loads are single phase loads, the line-to-neutral power is divided, as equally as possible amongst the phases to balance the loads on the generator’s windings.


In this case, “kilowatts” refers to generator output kilowatts or kWe (sometimes ekW). The actual load on the generator set engine are the kilowatts required to operate the load. This should be carefully sized because the engine cannot be efficient without an adequate load. Too little load may cause diesel engines to “carbon up” with unburned fuel. This leads to sooting of the lubricating oil, wear and eventually, premature engine failure. Conversely, too much load can shorten the life or damage the engine and generator.

Kilovolt-Amperes (kVA)

kVA is apparent load on the generator. The generator must be sized for the kVA requirement. Typically we use 0.8 as a power factor to estimate kVA. This is a convention and the power factor should be used if it is known. If the power factor is estimated, then the kVA will be the kWe ÷ 0.8 = kVA. (e.g. 100 kWe = 125 kVA where the power factor is 0.8)

Ambient Conditions

What will be the highest and lowest temperatures at which the generator will be expected to function? What will the maximum altitude be? Will it operate in dusty conditions? This will affect the air cleaner and pre-cleaner selection on the engine and may affect the fin spacing on the cooling radiator. Low temperatures will affect start-ability, oil grade and ancillary equipment.

Enclosure Requirement

If the generator will be housed in an enclosure you may want to think about the possibility of the enclosure being affected by ice buildup or other weather related concerns. Service access will normally be looked after by the supplier but deserves consideration. Is sound attenuation required?

Sound Control

Controlling the noise level of a standby generator is another factor that needs to be considered given that these generators are usually located in close proximity to residents or workers. Advance planning for sound attenuation includes having sufficient space for a suitable exhaust system and, if required, for an enclosure.
