What size of a Diesel Generator Set do I need?

On figuring what size of diesel generator set you need we are just giving you a quick overview and the information you will need when ordering your diesel generator set. Most diesel generator manufacturers have a sizing program available to help you understand electrical loads and will help you select what size generator you need for your application. Before you call a manufacturer, you might want to write down the nameplate data for all the loads you expect the generator to operate. Also think about future expansion and the sequence of the loads. The more information you give, the better change you end up with the right size of diesel generator set.

Since most of your equipment you are running does not run at 100% load at all time a rule of thumb is to size the diesel generator set to 80% of its capability, unless you're are thinking of expanding your operation.

What size of Diesel Generator Set do I Need - Electrical loads you want to power.

When deciding on what size of diesel generator set you need it depends what you are using the generator for. Are you planning on lights only, or industrial machinery that use electric motors, heating or air conditioning, water pumps or emergency equipment.? Lighting is somewhat a linear load and only require a small amount of power to operate them continuously.

Machinery that use electric motors with inductive style loads will have an increased starting power requirements. If the motors are using motor controls drives or soft starts, the starting power requirements will be somewhat reduced. A typical motor starting across the line can draw as much as five or six times the normal running power. A typical diesel generator set will start a motor at about one-third the size of the generator rating. In some case you will need a diesel generator set as large as the normal power grid supplied to your facility. To reduce the size you can consider staggering the start sequences of motor loads, this gives the generator a chance to recover from a motor start before another motor is connected. Purchasing a soft start or some type of motor controller  can cause the motor to only draw 1.5 times the normal running KVA or less during starting.

Also don't forget your heating, air conditioning or pumps that all use some form of motor. These all will have to be taken in consideration when figuring your electrical load. A quality manufacturer, like TEMCo Diesel Generator , will help you get the correct diesel generator set for your applications.

Find out what you need to consider before you purchase your emergency diesel generator set system. 


What does the term "Wet Stacking" mean in a diesel engine?
Diesel engines are designed to operate with a load. When a diesel engine operates considerably below the rated output level the engine can start to over-fuel or "Wet Stack".    


What is the function of the electronic controller on a diesel generator set?
The electronic controller are used for safe shutdowns and monitors the operation of the engine and generator functions.
