The JCB Generator Range: A Complete Guide


Generators Blog Banner.jpg

JCB Power Generation Products offers four distinct generator solutions to cover every type of site requirement:

  • QS Diesel Series: Reliable continuous and standby power for fixed or semi-permanent sites.

  • Stage V Rental Series: Rugged, towable generators engineered for high-demand hire conditions.

  • Electric Powerpacks: Zero-emission battery storage for noise-sensitive and low-load environments.

  • G60RS H Hydrogen Generator: Cutting-edge, net-zero power for strict urban emissions zones.

Whether you need backup power for a facility, off-grid continuous supply, or ultra-quiet zero-emission running, selecting the right machine comes down to your site constraints. This guide covers the pros, cons, and ideal applications of all four ranges, all of which are available to purchase through Scot JCB.

JCB QS Diesel Generator Range

The QS range is JCB's core diesel generator line, built for permanent and semi-permanent power on construction and industrial sites.

  • Power range: 20 - 330kVA at 50Hz, 22 - 375kVA at 60Hz, from the G20S up to the G330QS

  • Engine: JCB Diesel by Kohler on smaller models, moving to JCB 4 and 6 cylinder and Cummins engines on larger units, engines proven across more than 500,000 JCB machines worldwide

  • Control: Standard-fit Deep Sea Electronics 4520 control panel, with an optional 7310 panel and DSE 8610 models that can be synchronised together for larger site power

  • Noise and durability: As low as 62dBA, and tested to operate in temperatures over 50°C

  • Best for: Standby and backup power, permanent site installations, and harsh or remote environments

JCB Rental Series of Power Generators

The Rental Series is JCB's dedicated hire generator range, built to EU Stage V emissions standards.

  • Power range: 18 - 330kVA, from the G18RS V up to the G300RS V

  • Emissions: EU Stage V, with particulate matter reductions of over 95% compared to previous models

  • Control: Intelligent Load Management to protect against light load failures, automatic DEF fill systems, and JCB LiveLink telematics giving remote visibility of exhaust aftertreatment health

  • Noise: 63 - 68dBA at 7 metres, engineered for round the clock operation

  • Best for: Hire fleets, temporary site power, and projects that need Stage V compliance

JCB Electric Powerpacks

The Electric Powerpacks are JCB's battery powered alternative to a diesel generator, using lithium-ion technology for zero emissions at the point of use.

  • Storage capacity: 23 - 104kWh across the 1.25QE to 3.100QE range

  • Continuous output: 8kW on the smaller units, up to 36kW on the 3.50QE, 3.75QE and 3.100QE

  • Running costs: No fluids, filters or routine servicing, hybrid power generation with intelligent control, and LiveLink-enabled monitoring as standard

  • Best for: Indoor and underground work, noise-sensitive or out-of-hours sites, and applications where zero emissions are required

JCB Hydrogen Generator (Net-Zero Hybrid Power Solution)

The G60RS H is JCB's hydrogen-powered generator, paired with a JCB Powerpack to create a net-zero hybrid power solution built for the rental market.

  • Power output: 100kVA / 80kW combined, made up of 58kVA / 46kW from the generator and 45kVA / 36kW from the Powerpack, which holds 69kWh of battery storage

  • Emissions: Zero CO2 at the point of use, meeting Stage V emission limits without a DPF or DEF, so it suits stringent urban environments

  • Hybrid technology: Li-ion battery technology turns the engine off during off-peak periods, cutting fuel consumption by up to 60%

  • Noise: 60dB(A) at 7 metres

  • Best for: Rental fleets needing net zero, Stage V compliant power in urban or otherwise stringent environments

Key Benefits of Choosing the JCB Generator Range

While each range is built for a different job, several features run across all four

  • Remote monitoring: JCB LiveLink is available across the range, from fleet monitoring on the QS diesel range to standard-fit LiveLink on the Rental Series, Electric Powerpacks and the G60RS H hydrogen generator, giving real-time visibility of performance, location and machine health via PC or smartphone.

  • Built for site handling: Fork pockets and lifting points are fitted across every range, from the QS range's choice of lifting lugs to the Rental Series' and G60RS H's fixed lifting points and the Powerpacks' fork pockets, making every unit straightforward to transport and position on site

  • Durable construction: Robust protection across the range, from the QS range's zinc phosphate and seven-stage paint process to the Rental Series' and G60RS H's powder coat finish and heavy-duty baseframe, and the Powerpacks' all-steel enclosure.

  • Genuine parts and support: Backed by JCB's global network of parts centres, which can deliver around 95% of parts worldwide within 24 hours, plus the support of your local Scot JCB depot.

JCB Generator FAQs

What size generator do I need?

The right size depends on what you're powering and whether you need standby or continuous prime power. The JCB range spans from 8kW Electric Powerpacks up to 330kVA diesel units, so it's worth talking to your local Scot JCB depot to work out the right kVA or kW for your site.

What's the difference between a diesel generator and an electric powerpack?

A diesel generator burns fuel to generate power and suits permanent or semi-permanent installations needing continuous output. An Electric Powerpack stores power in a lithium-ion battery and releases it with zero emissions at the point of use, making it suited to indoor, underground or noise-sensitive sites.

Does JCB make a hydrogen generator?

Yes. The JCB G60RS H is a hydrogen powered generator, paired with a JCB Powerpack to deliver 100kVA / 80kW of combined power with zero CO2 emissions at the point of use. It meets Stage V emission limits without a DPF or DEF and is built for the rental market.

Are JCB generators available for hire?

Scot JCB sells and leases new JCB generators, but we do not offer short-term direct hire.

  • For Buying: We supply the complete JCB generator range - including the Stage V emissions-compliant Rental Series (G18RS V to G300RS V) and the G60RS H hydrogen model. Flexible financing is available through JCB Finance Flexilease (an Operating Lease designed specifically for JCB equipment).

  • For Direct Hire: If you require short-term hire, we can connect you with one of our trusted rental partners who run JCB fleets.

Do JCB generators meet Stage V emissions standards?

The Rental Series and the G60RS H hydrogen generator both meet EU Stage V standards as standard, with the Rental Series delivering particulate matter reductions of over 95%. Please check the specification for the model you need, as requirements vary by territory and application.

Can I monitor my generator remotely?

Yes. JCB LiveLink gives real-time visibility of your generator's performance, location and machine health via a PC or smartphone, and is available across the range.
