 The diesel generator sets for this sample project are sized for 30kw continuous/baseload, or 38kw [[ge:prime-vs-standby|prime power]]. The [[cp:start|Control System]] will automatically start a second generator if the first generator reaches 80% of its capacity, synchronize and operate them in parallel. When the load drops below 70% of the single genset capacity it will automatically unload and cool down the second genset. If the running generator shuts down due to a fault the second generator will automatically start and carry the load; if possible (in the case of a critical warning, like high water temperature or low coolant) the load will be transferred automatically before shut down.  The diesel generator sets for this sample project are sized for 30kw continuous/baseload, or 38kw [[ge:prime-vs-standby|prime power]].

-We prefer to purchase gensets built to specification from [[:Martin Energy]] rather than package sets from, for example, Cummins Power, Caterpillar, etc. The primary reason is that we can specify the size of generator end separately from the engine size, resulting in a better match for long-life. Most packaged power sets size the generator end for at least 80°C rise at rated power, which can result in a generator that is as hot as 130°C (266°F)! Standby power generators frequently operate at even higher temperatures. +We prefer to purchase gensets built to specification from [[:reference:Martin Energy]] rather than package sets from, for example, Cummins Power, Caterpillar, etc. The primary reason is that we can specify the size of generator end separately from the engine size, resulting in a better match for long-life.

 First, this is very wasteful of energy that could be doing useful work like operating your computer or lights. Second, this shortens the life of the generator end considerably. Time and temperature are the two primary factors governing the life of a generator - the higher the temperature, the shorter the life. If you intend to use your generator for a decade or more (and given the initial expense, why wouldn't you?), it is worth oversizing the generator end by as much as 30-40%. This results in cooler operation. There is no real downside to oversizing beyond the additional initial cost. Martin Energy normally does this for prime power gensets and can advise on the best options for your application.  First, this is very wasteful of energy that could be doing useful work like operating your computer or lights.

-The gensets can be built to order by [[:Martin Energy]]. Contact them for a quote and if you want to make changes from the standard design (generator size, engine size, model, features, etc.). +The gensets can be built to order by [[:reference:Martin Energy]].
