Buying electrical spare parts and tools online is a very easy way to acquire all the supplies you need for your daily requirements. However, now and more than ever, it's very important to make sure that the goods you're buying conform to the latest Australian Electrical Standards. These regulations constantly change, especially in the solar energy area.
The newest legislation brings variations to solar circuit protection installation, connection systems, solar enclosures and more. Here below we have outlined some of the most important changes you need to be aware of.
Whether you are an electrical contractor or an electrical online wholesaler, this information may be very useful:
- The solar array to inverter solar cables inside the buildings has to be in heavy duty conduit.
- The residential voltage rating of installation should not be above 600 Volts DC.
- Change of class 11 to class 1 for PV module insulating rating.
- PV array cabling must be double shielded, flexible and reach PV1-F.
- All PV wiring and components should be routed, supported and protected in accordance with AS/NZS 3000.
- Plastic cable ties are shall not be used as a principal means of support.
- Connectors are mated with connectors of the same type from the same manufacturer (12 month transition).
- An isolating-disconnection device has to be installed at the array if the inverter is more than 3 metres from the array.
- An isolating-disconnection device shall be installed adjacent to the inverter.
- Disconnection devices mustn't be polarity sensitive.
- Disconnection devices have to be AS/NZ 60898 or IEC 60947 certified, new weather-proof DC isolators and miniature DC circuit breakers comply with all disconnection standards.
- Earthing of all exposed metal module frames and mounting rails is obligatory.
- LV PV arrays with functional earthing, when there is an earth fault the EFI interrupts the earth fault and shuts the PV system down (1 year transition).
