AS / NZS Installation and safety requirements for photovoltaic (PV) arrays; AS / NZS Structural Design Actions Part 2: Wind Actions; AS / NZS. The draft of amendments to AS/NZS Installation and safety requirements for photovoltaic (PV) arrays was released for public. The new AS/NZS has been released as of the 6th November and is applicable as of 6th February. (3 months from the date of its.

The latest update includes several positive changes and clarifications but, compared with the release, the changes are nnzs. It will be difficult for barriers installed within enclosures to follow these requirements, unless purpose-made, compliant enclosures are used. This requirement was introduced with ns aim to reduce the risk of short circuit by providing additional mechanical protection.
Furthermore, as microinverters have a simple shutdown procedure, the method of isolating the system has also been incorporated into the fire emergency information sign and therefore a separate sign for the system shutdown procedure is not necessary.

This means that, nxs conduit is fixed to a wall, the solar labelling needs to be facing out. The IP4X rating requires the barrier to prevent penetration of objects with a 1 mm diameter or greater. Topics covered in recent GSES professional development days include commissioning, maintenance and fault finding; responding to solar tenders: These changes to the standard may assist in the uptake of this requirement, including the new colouring.
However, it will be difficult to demonstrate adequate protection – so, a safer alternative would be to adhere to the same requirements as domestic installations. 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.
This led to installers running 4 mm 2 earthing cables, independently, all the way from the array to the main switchboard. Bzs installed by Solar Powered Homes to achieve restricted access. A solar photovoltaic system is a unit that converts energy from sunlight into electrical energy. As previously stated, one of the key drivers of updates to the standard is the introduction of new products to the industry.
Although this may seem minor, not adhering to this can result in circulating currents between strings, even when the system is isolated. Season’s greetings Beamwidth testing for millimetre waves Telstra, Lexus to run connected vehicle field trial Trends in next-gen control room solutions Control room experts share their insights. Safety and Installation AS GSES has observed many PV systems installed since this update that have not included this warning, sometimes owing to the installer not being aware of the requirement or using up old-stock labelling kits.
Cages like this may no longer be necessary. An example shutdown procedure has also been displayed in the standard. In other areas of a building, cabling is more visible and therefore there is a lower risk of damage. UV-resistant HD conduit – a good option for achieving compliant conduit throughout the PV installation. A wholistic approach to long-term project success Partnering with an end-to-end provider enables experienced and highly trained specialists to 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.
The revised HD conduit requirements will have a significant impact when PV systems are installed on sheds and commercial buildings, where cavities are not used to run DC cabling. In these installations, it is now possible for the installation to be completed without HD conduit.
These clarifications will help to provide consistency in the industry and more reliable information for emergency workers. 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 barriers.
Solar installation standard – how the recent changes affect you. This article describes the key changes to the standard. This is the most effective way to achieve compliant insulation barriers between AC and DC circuits.

Compliance and Standards Opens in new window. Please consult the Contact Officer for more information and to ascertain the level of compliance that may be required. As Inspections Manager, Dan is responsible for the oversight of PV nzx audits around Australia, including technical review of inspection outcomes and the management and training of PV inspectors. After a challenging past five years, the electrical services industry is expected to nzx A wholistic approach to long-term project success.
For example, the labelling of conduit has been simplified from being required at each end and each change in direction, to being required at every 2 metres, consistent with the cabling labels.
This means that measurements taken during commissioning are not to be displayed on these signs. This will save installers a lot of work, especially if they are already using HD conduit and installing isolators within enclosures with lockable flaps. Within 50 mm, an insulation barrier will be required. A renewable energy certificate will only ae given where a written statement is provided by the installer of the unit that the installation complies with the following standards.
In addition, non-domestic buildings are permitted to be exempt from using HD conduit where the installation method otherwise achieves the objective of minimising short-circuit risk. He has invaluable experience in assessing Australian PV standards and has provided technical consultancy services to regulatory authorities. 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.

Code of Practice A code of practice is a set of rules which details how people in a az industry should behave. This is particularly useful for installing on roofs with small areas facing different directions.
Contact Email, Phone and Address Details for this service in simple two column table format, header then data. Another requirement introduced in bzs the warning zns DC isolators not de-energising the PV array and array cabling.
In many instances, this has resulted in installation of large cages around the inverter, isolators and cable runs Figure 3. The latest version of the standard has reduced the scope of this requirement, providing a more practical method of achieving the desired protection. SolarEdge power optimiser a DC-conditioning unit. Modules deteriorating over time can then compound the difference.
As DC-conditioning units and microinverters have unique electrical characteristics, it has been unclear how they should affect the labelling and nss displayed. Even for standard PV systems, the conditions used for calculating the displayed system ratings have varied.
Powering the future for Australian sustainable transport. However, please note that power limits and installation methods have been set for these product-specific requirements, so it is important that they are read carefully before 0533 these products.
