Air-cooled, Liquid-cooled or Portable — We Do It All
Whether you need a compact air-cooled home standby unit with automatic cutover, a liquid-cooled three-phase system for a commercial site, or a portable generator connected via a manual changeover, our Level 2 ASP team will specify and install the right Generac correctly the first time.
Why your Generac install needs a Level 2 ASP
A standby generator connects to your switchboard and the electricity network — work only an Accredited Service Provider can legally and safely carry out. As a Level 2 ASP and accredited Generac dealer, we cover every step.
Authorised grid connection
Only a Level 2 ASP can legally disconnect, reconnect and recommission your mains supply to integrate a standby generator.
Compliant changeover & ATS
We install changeover switches and ATS to AS/NZS 3000 so your generator can never backfeed the grid — protecting your home and network crews.
Switchboard & metering ready
If your switchboard needs upgrading or re-metering to support backup power, our Level 2 team handles it in the same visit.
Accredited dealer & installer
We supply, commission and back the warranty on your Generac — one accountable team from sizing to handover.

Yes. We're an accredited Generac dealer and a licensed Level 2 ASP, so we supply, install, commission and support the warranty on your Generac system. You deal with one accountable team from sizing and quote through to grid connection and handover.
A standby generator connects into your switchboard and, via a changeover or ATS, interfaces with the electricity network. Only a Level 2 Accredited Service Provider is authorised to disconnect, reconnect and recommission your mains and to install compliant changeover equipment that prevents dangerous backfeed to the grid.
It depends on the circuits you want to keep running during an outage. We carry out an on-site load assessment and recommend the right Generac model — from an air-cooled home standby unit to a liquid-cooled three-phase system — so you're never over- or under-sized. Every install is completed to AS/NZS 3000 and network rules.
Testimonials
"Chris was the professional, punctual and his services are exceptional. Chris re-wired the entire property, chased the electrical work in the bathroom and kitchen areas, left a clean and tidy environment and his open communication and dialogue was a welcomed experience.
When he quoted an arrival time, he was there. He talked me through what he was doing, and provided feedback/suggestions on how to tackle any issues. I felt part of the process, as opposed to being another Customer.
