The Many Benefits of Generator Paralleling
Are you considering a generator purchase, but have been hesitant because of issues with cost, lack of space or other implementation problems? Generator paralleling may be the solution that resolves many of the issues associated with standby power systems.
The advantages of placing multiple generators in parallel are numerous, and Generac's Modular Power System (MPS) offers a truly integrated solution that resolves the cost, complexity and implementation issues that have arisen in the past. Here are some of the key benefits:
Redundancy: During a power loss you rely heavily on standby power for critical functions as well as non-critical, low power functions. The redundancy of placing multiple generators in parallel provides increased reliability for critical loads. If one unit fails to come online, then a parallel unit provides the power needed.
Location Flexibility: Using multiple smaller generators instead of a single large unit offers greater location flexibility. Typically the footprint of a paralleled system is smaller and MPS units don’t have to be physically located together. Even weight distribution also allows for some rooftop installations. Space for switchgear and large external panel boards is eliminated.
Lower Cost: The engines used in smaller generators utilize advanced technology, and with economies of scale provide the lowest cost per KW in the industry. Operational efficiencies also kick in when only one unit is needed to cover power needs. This systems also retains the flexibility to expand the system as power needs increase. No need to over-spend on a large system that may not be fully utilized.
Service: With multiple generators, the individual units can be serviced without losing standby power. Maintenance items and replacement parts are relatively inexpensive and readily available.
Multiple Fuel Options: Generac offers integrated paralleling solutions in diesel, natural gas, and bi-fuel configurations.
All Generac standby generators are UL 2200 listed and our transfer switches are UL 1008 listed. UL listing verifies the kilowatt ratings of our generators and is your assurance that Generac standby systems meet the highest safety standards. Generac designs and manufactures all of the major components including the alternators, controls and enclosures. This unprecedented degree of control ensures that Generac products are built to the highest standards for quality, reliability and durability.

GTS Transfer Switches
Generac has been manufacturing their GTS model transfer switches for over a quarter of a century. “It is a great switch. Contractors like it because it is easy to install and work with. Owners and engineers like it because it is reliable and affordable, and our technicians love it because it is easy to trouble shoot and service. It’s been the staple of Generac’s transfer switch line for as long I can remember”, says Brian Wansor with Pro Power Solutions service department.
Generac is the only manufacturer of open transition switches to incorporate the two most common switching methods (inphase and delayed-transition) into the same ATS. Our inphase monitor provides safe, fast (160 msec) transfers between two live voltage sources when the source voltages are aligned (within 20°). If voltages are not inphase within an appropriate time, the system will automatically revert to the time delayed-transition transfer. If the inphase function is disabled, our GTS switches utilize delayed-transition transfer that allows load voltage to decay to a safe level before switching sources.
Generac’s GTS transfer switches feature:
- Status lights that indicate switch position and source status
- A programmable weekly exerciser that can be user-configured to transfer on exercise
- Independent voltage pickup and dropout adjustments
- Utility monitoring to protect against utility phase loss conditions
- Our front access test mode switch allows the entire standby system to be tested in either a normal or fast test mode.
Six Steps to Ensure Your Generator Will Operate Smoothly This Winter
The winter season typically causes major interruptions to the power supply. By performing regular generator maintenance you can ensure your generator will operate when called upon this winter! Here are our top six maintenance steps:
1. Replace worn out parts on a timely basis
2. Check fluid levels
3. Inspect batteries and clean connections
4. Do load bank testing
5. Verify control panel readings and indicators
6. Change fuel and air filters
Don't wait until a power emergency to think about maintenance. Call one of our certified service technicians if you have any questions about maintaining your generator this winter: 770-381-2424 or toll free 877-776-7693.
Featured Project: Korean Television Network
Equipment: Generac SD350 350 kW Diesel Generator, four automatic transfer switches
Location: Forsyth, GA
Founded in 1849 as the Forsyth Female Collegiate Institute, Tift College, as it was later named had a 40 acre campus located 20 miles south of Macon. It remained a private liberal arts women's college, and is especially known for it's College of Education. Many buildings on the campus are historic, and a portion of the property is listed on the National Historic Register.
In 1986 the college was acquired by Mercer University, which then closed it only a year later. After sitting vacant for nearly ten years, the property was acquired by the State to serve as the headquarters and training academy for the Georgia Department of Corrections. The move consolidated the Department's locations from five separate locations in the Atlanta area. "Moving our headquarters to Forsyth will position the Department to better protect the citizens of Georgia by effectively managing offenders," said Commissioner Brian Owens. "Because the majority of facilities are located south of the Metro Atlanta area, the Department will also gain efficiencies through consolidation and reduced travel time and costs."
The architecture firm of Lord, Aeck & Sargent, led the restoration and redevelopment of the campus and buildings. In addition to the thoughtful restoration of the buildings, a new central energy plant was constructed which serves the new energy-efficient mechanical systems installed in all of the substantial buildings.
Backup power was also needed throughout the campus. For one section they decided on a Generac SD350, a 350 kW Diesel Generator with a sound attenuated enclosure to provide quiet backup power. David Pull Associates, the electrical engineering on the project, designed the electrical end of the project including the generator. Working with HD Supply's facility maintenance side, Pro Power Solutions provided the generator system, which also included four automatic transfer switches. The backup power system was delivered and commissioned in a timely manner and all parties were pleased with the equipment and service."
