As DC-conditioning units and microinverters have unique electrical characteristics, it has been unclear how they should affect the labelling and signage displayed. Although installing the correct labelling and signage is important, where they are displayed is also vital.

Master Installer AS / NZS Update – Smart Energy Council

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.

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

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. 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. It is not only clear that AC and DC need to be segregated, but insulation barriers have also been clearly specified as the means of segregation.

It further ss that the earthing cable from the array frame can be connected to the AC earth conductor at the inverter. However, in doing so, installers need to ensure that the bzs system will not be interrupted if the inverter is removed and that the cable is of sufficient size according ad the system rating and type.

Installing AC and DC in the same enclosure, with a compliant insulation barrier, is difficult to achieve. This is particularly useful for installing on roofs with small areas az different directions. Within 50 mm, an insulation barrier will be required. You will be required to comply with the following standards if you intend to design or install a solar photovoltaic system.

Standards Catalogue

The previous standard only considered the scenario of a string of modules connected to a single MPPT and therefore did not allow for the flexibility of these new products. 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.

Cage 55033 by Solar Powered Homes to achieve restricted access. Code of Practice A code of practice is a set of rules which details how people in a certain industry should behave. As previously stated, one of the key drivers of updates to the standard is the introduction of new products to the industry.

Top energy conference in Melbourne next week Australia’s most comprehensive clean and renewable energy event, All-Energy Australia, SolarEdge power optimiser a DC-conditioning unit.

Signage Uncertainty around fire emergency information signs has not been limited to DC-conditioning units and microinverter systems. 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.

Topics covered in recent GSES professional development days include commissioning, maintenance and fault finding; responding to solar tenders: This article details the key updates and explains how they affect installers. DC-conditioning units and 5033 As previously stated, one of the key drivers of updates to the standard is the introduction of nza products to the industry. Please note that not all changes are included here, so GSES recommends that installers read the standard for themselves to ensure 50333 are aware of all current requirements.

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 ns requirements is to install AC and DC in separate enclosures and separate conduit Figure 2. However, the version of the standard provides clarification that reduces the need for installing these cages. Cages like this may no longer be necessary. Furthermore, the labelling needs to be visible. The areas requiring HD conduit are now limited to those that are not clearly visible, specifically, ceiling spaces, wall cavities and under floors.

Uncertainty around fire emergency information signs has not been limited to DC-conditioning units and microinverter systems. This led to installers running 4 mm 2 earthing cables, independently, all the way from the array to the main switchboard.

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.

He has invaluable experience in assessing Australian PV standards and has provided technical consultancy services to regulatory authorities.

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. This requirement was introduced with an aim to reduce the risk of short circuit by providing additional mechanical protection.

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. Australian Energy Storage Conference and Exhibition 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.

These clarifications will help to provide consistency in the industry and more reliable information for emergency workers. Please consult the Contact Officer for more information and to ascertain the level of compliance that may be required.

In many instances, this has resulted in installation of large cages around the inverter, isolators and cable runs Figure 3. Another requirement introduced in was the warning regarding DC isolators not de-energising the PV 5033 and array cabling. 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 using these products.
