What you should be asking?


  • There are lots of factors which have to be considered, there is no short way of explaining this.  If you have questions, please call, read, do the research.  Take your time, generators are a big investment in both the upfront cost and then in maintaining correctly.  Consider the time it takes to install a system correctly including inspections in reference to when you need the generator, honestly doing it correctly, the installation typically is spread across two weeks.  Make sure the company you are speaking with truly understands the theory associated with moving electrons, has the resource for taking care of generators not just installing them, and has experience with wide spread outages per the product they represent and have on the ground.  We are here to help, We can help!
  • Load calculations are required for the installation of all automatic generators.  Automatic generators incorporate sensing of the utility supply so if there is utility power loss, the generator engine cranks, the engine stabalizes, and automatically, thru a transfer switch, the generator system, transfers your home or business over to the generator.  You want to make sure the system to be installed will be able to handle the potential load connection without doing damage to whatever loads attach or even the generator itself.  An example, say your load calculation is 25 KW, this would require your generator, in order to be safe and last, should be at least a 25 KW due to the worst case scenario or load calculation.  With generators it is a huge mistake not to consider the worst case scenario.  I know, 25, 30, 40 KW system can be expensive so there is another option, using automatic load management you can install smaller generators, reducing cost , and the system makes sure you do not overload the generator.  Electrical code requires a load calculation, for your new system's sake, your valuables sake, your family's sake, ASK to see the load calculation.  If the load calculation exceeds the KW rating of the generator, load managment is needed.  You should also know, generator KW rating as stated by all manufacturers typically focuses on the KW rating if the unit is fueled by LP gas.  If your generator is to be fueled by natural gas, the actual KW rating is less.  Example a 20 KW unit fueled by natural gas can only provide 18 KW.  Another consideration, manufacture stated KW ratings are not always accurate, especially after they are used and operating temperatures start to affect the KW rating or output capacity.  To qualify this statement, we load test every unit we install or service thru service contracts.  We have 25+ years of load testing all brands for most all conditions, we have the data.  
  • Clearances from structure, openings in structure, other appliances such as AC units, and landscaping have to be considered.  Example, most home standby units being installed today are air cooled, this means they rely on the unit pulling in fresh air from typically the right side, using fans built into the generator, to cool the engine.  Imagine there is an AC positioned less than 36" from the generator intake.  It is your AC unit's job to dissapate heat, thru several fins which make up the outside AC.  Say it is 90 degrees outside, due to the location of the AC and its heat dissipation, this 90 degrees becomes even hotter.  This hot air pulled thru the generator with the additional heat created by the AC, will not be as effective, so longevity of the generator decreases, voltage output or generator's KW rating decreases.  Recommended clearance for adequate ventilation typically 36" plus, more is better.
  • Okay does it mean your generator system is installed correctly just because it cranks and the engine runs, even transfers and provides power for some lighting, NO.  During most testing of systems, or even during short duration outages, or longer outages where outside temperatures may not require your heating or AC systems work, the worst case scenario in reference to load attachment per your structure's potential load connection may not occur.  Generators should be load tested with external load banks to verify output voltages across several different load stage.  By load testing your are making sure response times in reference to engine recovery after load attachment is safe.  You should ask and demand this load test if you want real peace of mind, if you want your system to last and safely protect your structure's electrical loads.
  • Are generators, installed correctly, maintained correctly, represented by companies that actually understand the theory, inexpensive, NO.  This said due to our early introduction of residential home standby, representing product across multiple states requiring effective as well as practical service plans, with lessons learned thru multiple outages across different environments, we provide value and systems that WORK.
