Generac Industrial Standby Generators (SD and SDMD)
Generac Industrial standby generators cover a wide range, from the single-engine SD series (about 35 to 600 kW) to the large SDMD modular series (up to about 3250 kW) with onboard Deep Sea paralleling. They use aluminum or steel enclosures and are EPA-certified for standby duty. Comp-Utility specs, installs, and services Generac industrial generators across Central Texas.

From Commercial Standby to Modular Multi-Megawatt
Generac Industrial covers commercial and institutional standby with the SD series and reaches into large, scalable power with the SDMD modular platform and onboard paralleling.
Comp-Utility sizes, installs, commissions, and maintains Generac systems, from a single SD unit for a clinic or 911 center to paralleled SDMD power for larger critical facilities.

Frequently Asked Questions
What is the Generac SD series?
The Generac SD series is a line of custom-configured industrial standby diesel generators from about 35 to 600 kW, in aluminum or steel enclosures with PowerManager or Deep Sea controls and EPA certification for standby duty. It serves hospitals, 911 centers, commercial buildings, and industrial sites needing reliable backup power.
What is the Generac SDMD series?
The SDMD is Generac's largest diesel platform, reaching up to about 3250 kW in a single unit, built on a Baudouin engine with onboard Deep Sea paralleling (Modular Power System). It is designed for scalable, redundant power for large data centers and mission-critical facilities, allowing units to parallel into larger arrays.
What is Generac's Modular Power System (MPS)?
MPS is Generac's approach to paralleling, integrating multiple generators via Deep Sea onboard paralleling so they combine into a redundant, expandable power block without separate central paralleling switchgear in some configurations. This simplifies scalable, redundant backup. Comp-Utility designs MPS systems to meet your capacity and redundancy goals.
Are Generac industrial generators suitable for data centers?
Yes. The SDMD modular platform with onboard paralleling targets large and data center applications, while SD units serve smaller critical loads. For the largest hyperscale N+1 arrays, the 2 MW-class Caterpillar 3516 and Cummins QSK60 are also common. Comp-Utility compares options against your load, redundancy, and standardization preferences.
Does Generac offer natural gas options?
Yes. Generac offers gaseous (natural gas) industrial generators in the SG and MG series in addition to diesel SD and SDMD units, plus bi-fuel options. The right fuel depends on runtime, storage constraints, and emissions. Comp-Utility evaluates fuel choice as part of sizing and design. See our diesel vs natural gas guide for the trade-offs.
How do I size a Generac industrial generator?
Sizing accounts for running and starting loads, including motor inrush and UPS interaction, plus redundancy and runtime. The SD series covers smaller loads and the SDMD scales much higher with paralleling. Comp-Utility's engineers model your loads and recommend the model, configuration, and any paralleling to fit.
What maintenance do Generac industrial generators require?
They require regular oil, filter, and coolant service, fuel system maintenance, starting battery testing, controls verification, exercising, and periodic load bank testing, with NFPA 110 expectations for life-safety systems. Comp-Utility builds and executes a maintenance and testing program tailored to the unit and load criticality.
