Prime power is the maximum continuous power rating at 0.8 power factor; standby ratings are higher. All models are multi-voltage (single- and three-phase) — small/medium units select voltage on a 3-position switch, while PG240 and up use a Link Board Panel. Sound is measured at 23 ft (7 m) at 100% load. Operating weight is for the enclosed unit with running gear, ready to run. The PG70, PG100, PG325, PG400 and PG570 are paralleling-capable. Specifications subject to change — contact Carleton Equipment to confirm.
Understanding the Lineup
Five Tiers, One Lineup
Bobcat portable generators sort into five classes by prime power (kVA / kW) and the kind of job they're built for. Here's how to read the lineup before you compare specs.
Small
25–50 kVA
20–40 kW
Compact, Doosan-powered towables. Light, maneuverable power for jobsite trailers, lighting, hand tools and small backup.
PG25 · PG40 · PG50
Medium
70–100 kVA
56–80 kW
Cummins-powered, paralleling-capable mid-range units — the quietest in their class. Multi-tool sites, small commercial backup and events.
PG70 · PG100
Large
125–154 kVA
100–123 kW
Higher-output towables for roadwork, utilities and mid-size commercial standby — a wide range of selectable output voltages.
PG125 · PG150
Extra-Large
181–334 kVA
145–267 kW
Big-industrial power on a Link Board Panel — tower cranes, large jobsites, utilities and infrastructure. PG325 is paralleling-capable.
PG190 · PG240 · PG325
400 kVA+ · No Min Load
402–570 kVA
322–456 kW
The industry's only 400-kVA-or-larger generators with no minimum load requirement. Major construction, large events and standby; both parallel.
PG400 · PG570
Prime vs Standby Power Prime power is continuous output for the full duration of the job; standby is emergency-only backup at a higher rating but limited hours. Size to the prime rating for working power.
Single- vs Three-Phase Single-phase (120/240 V) runs lighting, hand tools and small loads; three-phase (208/480 V) is required for motors, HVAC, pumps and most industrial equipment. Bobcat units are multi-voltage.
kVA vs kW kVA is apparent power, kW is real (working) power — related by power factor (0.8 typical, so 100 kVA ≈ 80 kW). Size to both your kW load and the kVA rating.
How to Choose
Sizing It Right — Running & Starting Watts
Generators size by power, not airflow. Add up the running watts of everything you'll run at once, then account for starting (surge) watts — motors briefly draw 2–3× their running load to start. Match a generator whose prime kW covers the running total and whose surge capacity handles your largest motor start.
| Equipment / Load | Typical Running | Starting Surge |
|---|---|---|
| LED light tower | 1–2 kW | Minimal |
| Electric hand tools (per circuit) | 1.5–3 kW | 1–2× |
| Concrete mixer / small 3Ø motor | 2–7 kW | 2–3× |
| Submersible / trash pump | 3–15 kW | 2–3× |
| Stick welder (~200 A) | 7–12 kW | Moderate |
| Site office / trailer (HVAC + lights) | 5–15 kW | Moderate |
| Temporary HVAC / electric heat | 20–100 kW | Moderate |
| Tower crane | 30–75 kW | High (hoist start) |
| Event stage, sound & lighting rig | 50–300 kW | Moderate |
| Industrial / facility standby | 100–456 kW | Varies |
Lighting, jobsite trailers, small tools, light backup — single small loads
→ Small · PG25 / PG40 / PG50
Multiple tools, small commercial backup, small events
→ Medium · PG70 / PG100
Roadwork, utilities, mid-size commercial standby
→ Large · PG125 / PG150
Tower cranes, large industrial sites, infrastructure
→ Extra-Large · PG190–PG325
Major construction, large events, industrial standby — no minimum load, parallel-ready
→ 400 kVA+ · PG400 / PG570
Rule of thumb: total the running watts of everything running at once, confirm the unit can handle your largest motor's starting surge (often 2–3× its running watts), then add about 20–25% headroom for growth and voltage stability. Choose three-phase for motor, HVAC and industrial loads. Not sure? Tell us your equipment and we'll calculate the load for you.

Power You Can Count On
Clean, Reliable Power
Three Bobcat technologies work together to deliver steady, protected, scalable power — so your generator runs clean under any load and grows with the job.
1
Automatic Voltage Regulation
AVR holds output voltage steady as loads come and go — clean, stable power that protects sensitive tools, electronics and motors.
2
Intelligent Load Management (ILMS)
Bobcat's exclusive ILMS option protects the engine and aftertreatment during low-load operation — minimizing wet stacking, sludge buildup and costly repairs.
3
Paralleling
Synchronize multiple units for more power or redundancy — the PG70, PG100, PG325, PG400 and PG570 parallel (up to 32 machines on the PG570).
Every current model is a Tier 4 Final clean-diesel unit with a heavy-duty, sound-attenuated enclosure and easy-access service panels — dependable, efficient power that's ready to tow to the next job.
Good to Know
Emissions & Towing
Every current model is a Tier 4 Final (T4F) clean-diesel unit. The larger units (PG125 and up) use SCR aftertreatment with Diesel Exhaust Fluid (DEF) — keep the DEF tank topped off (roughly 24 gal on the PG190–PG325, 46 gal on the PG400 and PG570). The PG400 adds a diesel particulate filter (DOC/DPF/SCR), while the PG570 runs SCR with no EGR. It's modern, efficient diesel power with minimal emissions upkeep.
Operating weights run from about 3,060 lbs (PG25) up to roughly 23,574 lbs (PG570), so match the unit to the right tow vehicle and hitch class. Larger units ride on heavy-duty, NHTSA-compliant tandem/dual-axle running gear with lights, fenders and brakes for road-ready towing. Ask us about the right towing setup for your fleet.

Frequently Asked Questions
Have a question about buying, renting, or servicing a Bobcat portable generator? Find answers below or reach out to your nearest Carleton Equipment location.
What is a portable generator?
A portable generator is a mobile power unit that converts diesel fuel into reliable electrical power for tools, lighting, and equipment on jobsites without grid access. Bobcat portable generators deliver dependable performance wherever you need electricity — construction sites, events, disaster recovery, or remote operations. Towable, diesel-powered generators range from 25–1140 kVA, providing single- and three-phase power to run everything from hand tools to jobsite trailers and tower cranes. Each model is built with heavy-duty enclosures and sound attenuation for quiet operation, automatic voltage regulation (AVR) for steady clean output, Tier 4 diesel engines for efficiency and emissions compliance, and easy-access service panels for minimal downtime.
How do I choose a portable generator?
Selecting the right generator depends on your power demand and operating conditions. Consider: Power output — match the generator's kW, kVA, or amperage rating to the total running load of your equipment. Voltage needs — choose single-phase for smaller tools and lighting, or three-phase for industrial applications. Runtime requirements — larger fuel tanks support long shifts without refueling. Mobility — compact, trailer-mounted units are ideal for moving between jobsites. Environment — sound-attenuated, weather-protected enclosures are essential for urban or harsh environments. Our team at Carleton Equipment can help calculate your total load and recommend the best model — submit a quote request or contact your nearest location.
What's the difference between a portable generator and other power sources?
Portable generators stand apart for their flexibility and reliability. Compared to standby generators: portable units are mobile and designed for temporary use, while standby generators are fixed installations for permanent backup power. Compared to inverter generators: industrial portable generators offer far greater capacity (25–570 kVA) and three-phase capability for heavy-duty equipment — small inverter generators typically only offer single-phase and less than 15 kW output. Compared to light towers: light towers are primarily for integrated lighting with limited power output, while dedicated portable generators provide scalable, multi-connection power for any jobsite condition.
What sizes are available for Bobcat portable generators?
PG25–PG150: Compact towable models producing 25–150 kVA, ideal for residential construction, small jobsite power, and jobsite trailers. PG240–PG325: Mid-size units delivering 200–325 kVA for roadwork, utilities, and tower cranes. PG400–PG1140: Large diesel models producing 400–1140 kVA with load management technology and paralleling capability for major construction projects or emergency power applications. Every Bobcat portable generator is built for easy towing, quiet operation, and superior efficiency in the field.
What is the Bobcat ILMS and why does it matter?
ILMS stands for Intelligent Load Management System — an option exclusive to Bobcat generators. It protects the engine and exhaust aftertreatment system during low-load operation by minimizing wet stacking, harmful sludge buildup, and the need for costly repairs. If your generator will frequently run at partial load, ILMS is a worthwhile investment in long-term reliability and reduced maintenance costs.
Can Bobcat generators be paralleled together?
Yes. Select Bobcat generator models — PG70, PG100, PG325, PG400, and PG570 — are available with an advanced paralleling control system that allows multiple units to be synchronized and run together. This is ideal for applications requiring more power than a single unit can provide, or for redundancy and backup power configurations.
