INDUSTRIAL POWER FROM GENERAC’S  
MODULAR POWER SYSTEMS
For applications requiring greater amounts of standby 
power, the MQT100 and MQT150 models are ideal. 
Available through your local Generac Industrial 
Dealer, the output of these gensets can be combined 
to form a Generac Modular Power System (MPS). 
MQT Series Modular Power Systems are building 
blocks that link together to combine the power output 
equal to one large single generator. With the ability to 
parallel up to ten 100 kW units or up to ten 150 kW 
units, these generators can satisfy higher end 
requirements ranging from 100 to 1500 kW.
Redundancy
Because each MQT generator within the system backs up the others, critical loads receive 
extra protection and building managers enjoy greater peace of mind.
Serviceability
MQT generators use modified high volume truck or industrial engines that can be serviced 
using readily available, cost-effective parts. Since each generator backs up the others, 
servicing can be accomplished without losing backup power to critical loads.
Scalability
A Generac Modular Power System can be expanded as facilities grow. There is no need       
to replace the system if future power requirements exceed projections and no need to    
over-spend on a larger system that might never be fully utilized. 
Flexibility
MPS modules provide unmatched flexibility because they can be placed in any configuration 
side by side, end to end, together or apart. They are light enough for most rooftop 
applications and the lower weight eliminates the need for heavy-duty cranes and material 
handlers during installation.
THE GENERAC 
INDUSTRIAL DEALER 
NETWORK
Installation, start-up and servicing of 
Modular Power Systems require 
specialized knowledge and expertise. 
Generac Industrial Dealers have 
factory-trained personnel to ensure 
that your customers get the best 
possible solution, fast delivery, 
professional installation and start-up.
If a customer needs a diesel-powered 
generator or a generator size that is 
beyond the scope of the QT Series 
line, a Generac Industrial Dealer can 
meet requirements up to 9,000 kW.
Generac Industrial Dealer certified 
service technicians are fully trained 
on all QT Series generators and  
can provide your customers with 
hassle-free maintenance and 
service agreements.

 TWIN PACK 
FOR HIGHEST POWER 
DENSITY
When space is at a premium and 
reliability is critical, no other 
manufacturer comes close to 
Generac’s Gemini Twin Pack. 
Part of the MPS family, these units 
feature two 500 kW generators inside 
a single, weather resistant and sound 
attenuated enclosure. The exclusive 
PowerManager™ control system 
allows for combining the output of 
large, single engine gensets with a 
significant improvement in reliability.

BI-FUEL ™
   Longest Run Times in the Industry
Generac Bi-Fuel generators start on diesel fuel and add natural gas as load is applied. 
During an outage, they typically operate on a mixture of up to 70% natural gas and 
30% diesel fuel (contact factory for product specifications). If the natural gas supply is 
interrupted, the generator automatically switches to 100% diesel without any power drop 
during the transition.
