Turn Key Generator Solutions for Complex Sites

Engineered power systems for strata, high rise, hotels and industrial facilities

Protect your site from costly outages with fully engineered generator solutions.

We deliver turn key projects from start to finish.

At Reactive Generators we design, supply, install and commission complete standby power systems that keep lifts, pumps, air conditioning, servers and business critical operations running with full reliability. Every system is designed for your building and your electrical load, then installed, tested and commissioned by specialist technicians. The result is a modern, compliant and dependable backup power system that is built to perform when the mains supply fails.

We manage the entire installation including:

  • Load assessments and site engineering

  • Generator selection and sizing

  • Delivery, cranage and placement

  • Structural and civil works

  • Fuel tank supply and fuel system installation

  • Switchboard works and transfer system integration

  • Full testing, commissioning and certification

  • Ongoing service schedules and performance checks

Every project is delivered with clear reporting, compliance documentation and a reliable handover process.

Complex buildings need more than a basic generator. They need a system designed for:

  • Multiple lift cars

  • Stormwater and sewage pumps

  • Fire systems

  • Server rooms and communications

  • Building management systems

  • Commercial kitchens

  • Guest or tenant amenities

  • Lighting, security and access

Our team designs generator solutions that support these critical services without overload or interruption. We specialise in solving constraints often found in large buildings including tight plant areas, rooftop locations, noise limits and restricted access.

A generator is only part of the solution. The supporting systems determine how well it performs during an outage.

We integrate and upgrade:

  • Automatic Transfer Systems

  • Switchboards and protection

  • Fuel control systems

  • Monitoring and alarms

  • Remote supervision and SCADA

  • Emergency shutdown controls

All work is delivered to Australian Standards with full testing and sign off.

A loss of mains power stops essential services instantly. Lifts stall, pumps shut down, basements flood, air conditioning fails and server rooms overheat. These events create safety risks, disruption to residents or guests and significant commercial loss.

Our engineered generator solutions remove this risk with reliable standby systems that activate automatically. We manage everything from planning and approvals to final commissioning, giving your site continuous protection during any outage.

When power reliability is essential, you need a project delivered without delay. Our team handles engineering and installation quickly and safely, with clear communication from start to finish.

Once your system is operational, our service technicians provide ongoing maintenance and performance testing to ensure your generator is ready for the next outage.

A generator is only one part of a complete power solution. The supporting systems determine how reliably it performs during an outage.

We integrate and upgrade the critical systems that keep essential services running, including:

  • Automatic Transfer Systems
  • Switchboards and protection
  • Fuel control systems
  • Monitoring and alarms
  • Remote supervision and SCADA
  • Emergency shutdown controls

All work is completed to Australian Standards with full testing and sign off.

Excellent service the Pramac Generator we purchased has not missed a beat over last two year and with remote monitoring suits our requirements. If you need a generator I would contact Hal and team to source it for you.
Harry Symes
Reactive Generators were very helpful and knowledgeable. Their service is second to none and I can't not recommended anyone better.
Nick Vermeulen
Exceptional service regarding marine generator repair, or conversion. Hal and his team offered me a turn key solution to utilise my Kubota marine engine and convert to a newer more reliable power source or fix the outdated alternator. I chose to convert and have the latest technology running from my ever reliable Kubota. Hal designed a system that is so efficient and fully automated on budget, on time, could not be happier. Reactive generators business ethics is unsurpassed, a truly trustworthy company to deal with and not to forget outstanding customer service. Nick V. Brisbane
Rowan McPhee
Hal and the team at Reactive Generators are awesome guys to work with, and would recommend them 100% to anyone who requires their services. Honest, reliable, hard working and great communication with the can do attitude. Which makes them your first choice in anything to do with Electrical and Mechanical services.

We found Hal and Josh outstanding. No other contractors would even look at the replacement control system because of the age of our generator except for Reactive Generators. Can't recommend them enough!
Matthew Vandenbrink
As a Poultry farmer, power is critical on my farm.. Reactive generators have just installed a brand new Pramac generator as well as refurbishing an existing generator. All control systems have been upgraded to digital/electronic. I can’t say enough about Hal and his team, not only were they price competitive, service with a smile and delivered on time and on budget. I would recommend Reactive Generators to any business requiring critical power needs.
Tanya Jeffrey
Great customer service Hal, thankyou so much for your efforts in supplying our generator and the customer support for the electrician on install. Our community will be very grateful when we are out of power and our pub can still supply cold beer and meals. Can’t wait to catch up for a beer when you are up this way. Cannot recommend this company enough, great work. From all us at Carmila hotel🍺🍺
Brooke Renwick
After being quoted on a replacement alternator from another supplier Reactive Generator we're able to correctly diagnose the issue which ended up being as simple as an adjustment to the automated voltage regulator. Fast and effective service and will be using these guys for all our generator needs moving forward. The mobile service is a huge benefit as well - greatly appreciated guys!
Nami Scanlon
First class service and best technically trained staff i have come across for years. I will only be using reactive generators for all future services and advise from now on. many thanks again Hal. darrell Kru Catering
