GENERATOR SUPPLY & CONNECTION SYDNEY

Connecting a generator to a property's electrical infrastructure isn't as simple as plugging it in. A proper generator connection requires a changeover switch (also called an automatic or manual transfer switch) that safely isolates the generator from the network — preventing dangerous back-feed that can injure network workers and damage your equipment. Sydney Power Group installs generator connections and backup power infrastructure for residential, commercial, and strata properties across Sydney.

Manual and Automatic Changeover Switches

A changeover switch is the key component in any generator installation. It prevents the generator from feeding back into the network, protects your generator from damage when mains power is restored, and gives you a safe, controlled switchover between sources. We install both manual changeover switches — where you physically select between mains and generator — and automatic transfer switches that detect a mains failure and switch to generator power within seconds, without manual intervention.

Permanent Generator Connections

Permanently installed generators for critical loads — medical equipment, refrigeration, cold rooms, or essential services — require a dedicated connection at the switchboard with appropriate protection and metering. We design and install permanent generator connections to Ausgrid and Endeavour Energy standards, coordinate any required network notification, and commission the system with load testing to confirm it operates correctly under fault conditions.

Strata Building Backup Power

Strata buildings — particularly those with lifts, common area lighting, security systems, and basement car parks — are increasingly installing backup power to maintain essential services during network outages. We work with strata managers and body corporate committees to design and install generator infrastructure that meets essential load requirements without overloading the generator, and ensure the installation satisfies building code requirements and the network distributor's technical standards.

Emergency Generator Hire and Connection

When a property suffers a major infrastructure failure and the repair will take more than a day, a temporary generator provides an interim power supply while the permanent repair is completed. We coordinate emergency generator hire and connect hired generators to the property's switchboard safely, with the correct changeover switching so the site is energised without safety risks. This is particularly valuable for commercial tenants and strata buildings where extended outages are not acceptable.

Solar and Battery Integration

Combining a generator with rooftop solar and battery storage creates a more resilient microgrid that reduces generator run time and fuel costs. We configure changeover and protection arrangements for combined solar, battery, and generator systems — ensuring the control logic correctly manages the priority between sources and the system remains fully compliant with network export requirements and AS/NZS 3000.
