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.

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.
Solar installation standard – how the recent changes affect you
As previously stated, one of the key drivers of updates to the standard is the introduction of new products to the industry. This led to installers running 4 mm 2 earthing cables, independently, all the way from the array to the main switchboard. AC and DC installed in separate conduit and enclosures.
Surge protection design philosophy.
Furthermore, the labelling needs to be visible. 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 nzz these products.
Signage Uncertainty around fire emergency information signs has not been limited to DC-conditioning units and microinverter systems. Nonetheless, DC PV cables within a building, but 50033 within these cavities, need to be protected with medium-duty MD conduit.
However, if a lockable room is used for providing restricted access then these precautions are not necessary. A code of practice is a set of rules which details how people in a nzw industry should behave. Please consult the Contact Officer for more information and to ascertain the level of compliance that ns be required. Another requirement introduced in was the warning regarding DC isolators not de-energising the PV array and array cabling.
This means that, if conduit is fixed to a wall, the solar labelling needs to be facing out. Furthermore, as microinverters have a simple shutdown procedure, the method 503 isolating the system has also been incorporated into the fire ass information sign and therefore a separate sign for the system shutdown procedure is not necessary. It is nzzs only clear that AC and DC need to be segregated, but insulation barriers have also been clearly specified as the means of segregation.
Although installing the correct labelling and signage is important, where they are displayed is also vital. 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.
Top energy conference in Melbourne next week Australia’s most comprehensive clean and renewable energy event, All-Energy Australia, Although this may seem minor, not adhering to this can result in circulating currents between strings, even when the system is isolated.
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.
A code of practice can be defined as a result of legislation or by industry regulators and bodies. Even for standard PV systems, the conditions used for calculating the displayed system ratings have varied.
He has invaluable experience in assessing Australian PV standards and has provided technical consultancy services 50333 regulatory authorities. An example of this may be the use of cable trays. The latest update includes several positive changes and clarifications but, compared with the release, the changes are minimal.
For DC-conditioning units, the voltage and current displayed on 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. An example shutdown procedure has also been displayed in the standard. SolarEdge power optimiser a DC-conditioning unit.

Therefore, installers upgrading old systems with new parallel strings need to pay particular attention to this requirement. After a challenging past five years, the electrical services industry is expected to experience Although using only UV-resistant HD conduit increases the cost 50333 materials, it increases the durability of the system and may reduce the installation time.
However, it will be difficult to demonstrate adequate protection – so, a safer alternative would be to adhere to the same requirements as domestic installations. The latest version of the standard has reduced nzzs scope of this requirement, providing a more practical method of achieving the desired protection.

Topics covered in recent Nzzs professional development days include commissioning, maintenance and fault finding; responding to solar tenders: 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.
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.
zns However, the version of the standard provides clarification that reduces the need for installing these cages. These clarifications will help to provide consistency in the industry and more reliable information for emergency workers. 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. Description You will be required to comply 5303 the following standards if you intend to design or install a solar photovoltaic system.

In addition to this, AC and DC switchgear cannot share the same mounting rail, unless it is constructed from a non-conductive material. 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.

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.
A simple way to abide by these requirements is to install AC and DC in separate enclosures and separate conduit Figure 2.
