Powering the future for Australian sustainable transport. Australian Energy Storage Conference and Exhibition However, in doing so, installers need to ensure that the earthing system will not be interrupted if the inverter is removed and that the cable is of sufficient size according to the system rating and type. This could lead to a potential hazard if the circuit is disconnected without adequate protection such as a load-breaking DC isolator.

Standards Catalogue

It is not only clear nxs AC and DC need to be segregated, but insulation barriers a also been clearly specified as the means of segregation. Topics covered in recent GSES professional development days include commissioning, maintenance and fault finding; responding to solar tenders: To assist PV installers in keeping on top of changes in the industry, like these necessary standards updates, the Clean Energy Council has put in place a continuous professional development CPD program.

UV-resistant HD conduit – a good option for achieving compliant conduit throughout the PV installation. Therefore, installers upgrading old systems with new parallel strings need to pay particular attention to this requirement.

In addition, non-domestic buildings are permitted to be exempt from using HD conduit where the installation method otherwise achieves the objective of minimising 533 risk.

Modules deteriorating over time can then compound the difference.

He has invaluable experience in assessing Australian PV standards and has provided technical consultancy services to regulatory authorities. GSES also provides professional development days at locations around Australia, which give installers the opportunity to achieve the annual requirement of CPD points in a single day. While fewer areas will now require HD conduit, the change may not have a significant impact on PV installations in the domestic market.

A solar photovoltaic system is a unit that converts energy from sunlight into electrical energy.


The IP4X rating requires the barrier to prevent penetration 503 objects with a 1 mm diameter or greater. The only exception to this is when cabling is outside enclosures, where 50 mm separation can be used.

One of the main benefits of these new products is that individual modules can be orientated in different directions, owing to the ability of these products to track the maximum power point MPP of each module independently.

Within 50 mm, an insulation barrier will be required. SolarEdge power optimiser a DC-conditioning unit. The latest update includes several positive changes and clarifications but, compared with the release, the changes are minimal. Uncertainty around fire emergency information signs has not been limited to DC-conditioning units and microinverter systems.

It now states that, if HD conduit is used on all accessible cabling, up to and including the inverter terminals, and the DC isolators and protection devices are in enclosures – only accessible with a tool – then there is no need for additional bzs.

For DC-conditioning units, the voltage and current displayed aas the fire emergency information signs are to be equal to the maximum input ratings of the inverter, consistent with sizing the load-breaking DC isolator.

After a challenging past five years, the electrical services industry is expected to experience Although using only UV-resistant HD conduit increases the cost of materials, it increases the durability of the system and may reduce the installation time. A wholistic approach to long-term project success. Keeping on top of changes To assist PV installers in keeping on top of changes in the industry, like these necessary standards updates, the Clean Energy Council has put in place a continuous professional development CPD program.

Cages like this may no longer be necessary. Surge protection design philosophy.

Signage Uncertainty around fire emergency information signs has not been limited to DC-conditioning units and microinverter 533. Nonetheless, DC PV cables within a building, but not within these cavities, need to be protected with medium-duty MD conduit. A renewable energy certificate will only be given where a written statement is provided by the installer of the unit that the installation complies with the following standards.

Global Sustainable Energy Solutions GSESwith its extensive experience in PV training, design and inspections, is regularly involved in discussions over practical methods that installers can use to implement the latest standards and guidelines. It also further specifies that, where multiple arrays are installed, the voltage shall be the highest value present and the current shall be the sum of all array currents. Compliance and Standards Opens in new window.


Standard updates like these are a necessary hurdle for an industry that is constantly growing in size and experience, and encounters an ever-broadening range of products.

As DC-conditioning units and microinverters have unique electrical characteristics, it has been unclear how they should affect the labelling and signage displayed.

As Inspections Manager, Dan is responsible for the oversight of PV installation audits around Australia, including technical review of inspection outcomes and the management and training of PV inspectors. DC-conditioning units and microinverters As previously stated, one of the key drivers of updates to the standard is the introduction of new products to the industry.

An example shutdown procedure has also been displayed in the standard. For microinverter systems, displaying these ratings is generally not necessary as the voltage is usually the same as for other AC electrical systems VAC. A code of practice is a set of rules which details how people in a certain industry should behave. Top energy conference in Melbourne next week Australia’s most comprehensive clean and renewable energy event, All-Energy Australia, Please note that not all changes are included here, so GSES recommends that installers read the standard for themselves to ensure they are aware of all current requirements.

Although installing the correct labelling and signage is important, where they are displayed is also vital. Although this may seem minor, not adhering to this can result in circulating currents between strings, even when the system is isolated.
