Everything Your Generac Install Needs, in One Place
From load sizing to compliance documentation — we handle the whole job end-to-end.
Built to meet SDA backup power requirements
The SDA Design Standard calls for backup power provision in High Physical Support dwellings. We design and install standby systems that meet it — and keep residents safe across every SDA category.
High Physical Support ready
Backup power provisioned for dwellings where residents rely on powered, life-critical equipment.
Automatic & hands-free
An automatic transfer switch restores power within seconds — no staff intervention required.
Whole-home or essential circuits
Cover the whole dwelling or a managed essential-loads panel to suit the build and budget.
Designed with your builder
We work alongside SDA builders and developers from design through to certification and handover.
Automatic backup you can rely on
A standby generator restores power without anyone needing to be home to act. We recommend it as one layer of a wider outage plan that also includes battery/UPS backup and registering as a life-support customer with your energy provider.
Restores power in seconds
An automatic transfer switch detects the outage and starts the generator within 45–75 seconds — hands-free, day or night.
Clean, stable power
Generac True Power technology delivers under 5% harmonic distortion, safe for sensitive medical electronics.
Runs for days, not minutes
Natural gas or LPG fuel gives long run times that battery-only backup can't match in an extended outage.
Monitored remotely
Built-in Mobile Link lets you and our team check generator status and battery health from a phone.
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.

Home Standby
Whole-home air-cooled backup that starts automatically within seconds of an outage.
Commercial & Three-Phase
Liquid-cooled standby power for offices, retail, medical and essential services.
Portable + Changeover

Seamless cutover so power restores without you lifting a finger.

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.

FAQs
By ensuring your property is inspected by High Demand Electrical, you are taking a significant step towards securing its safety and enhancing its efficiency. Reach out today to learn more about how we can assist you in maintaining a safe and compliant electrical environment.
Yes. A whole-house Generac standby generator connects into your switchboard and the electricity network through an automatic transfer switch, so it must be installed by a licensed Level 2 ASP. High Demand Electrical is an accredited Generac dealer and Level 2 ASP, so we handle supply, installation, grid connection and commissioning end to end.
An automatic transfer switch (ATS) detects the outage, safely isolates your home from the grid and starts your Generac within seconds. When mains power returns it switches back and shuts the generator down automatically — no manual switching and no risk of backfeed to the network.
It depends on whether you want to run essential circuits or the whole home, including ducted air-conditioning. We carry out a free on-site load assessment and recommend the right Generac Guardian model — from 10kW up to 26kW air-cooled — so your system is never over- or under-sized.
