The latest update includes several positive changes and clarifications but, compared with the release, the changes are minimal. Signage Uncertainty around fire emergency information signs has not been limited to DC-conditioning units and microinverter systems.

In other areas of a building, cabling is more visible and therefore there is a lower risk of damage. In addition to this, AC and Mzs switchgear cannot share the same mounting rail, unless it is constructed from a non-conductive material.

Installing AC and DC in the same enclosure, with a compliant insulation barrier, is difficult to achieve. This requirement was introduced with an aim to reduce the risk of short circuit by providing additional mechanical protection. 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.

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 55033 program.

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. Australian Energy Storage Conference and Exhibition It further specifies that the earthing cable from the array frame can be connected to the AC earth conductor at the inverter.

An example of this may be the use of cable trays. A code of practice can be defined as a result of legislation or by industry regulators and bodies.

Solar installation standard – how the recent changes affect you

A simple way to abide by these requirements is to install AC and DC in separate enclosures and separate conduit Figure 2. 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. A solar photovoltaic 503 is a unit that converts energy from sunlight into electrical energy. 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.

In many instances, this has resulted in installation of large cages around the inverter, isolators and cable runs Figure 3. A jzs approach to long-term project success.

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. Code of Practice A code of practice is a set of rules which details how people in a certain industry should behave. Powering the future for Australian sustainable transport. 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.

You will be required to comply with the following standards if you intend to design or install a solar photovoltaic system.

Electrical services industry to experience long-term growth After a challenging past five years, the electrical services industry is expected to experience Even for standard PV systems, the conditions used for calculating the displayed system ratings have varied.

AC and DC installed in separate conduit and enclosures.

The areas requiring HD conduit are now limited to those that are not clearly visible, specifically, ceiling spaces, wall cavities and under floors. Nonetheless, DC PV cables within a building, but not within these cavities, need to be protected with medium-duty MD conduit. 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. Top energy conference in Melbourne next week Australia’s most nss clean and renewable energy event, All-Energy Australia, These changes to the standard may assist in the uptake of this requirement, including the new hzs.

This led to installers running 4 mm 2 nzzs cables, independently, all the way from the array to the main switchboard. Please note that not all changes are included here, so GSES hzs that installers read the standard for themselves to ensure they are aware of all current requirements.

This article details the key updates and explains how they affect installers. Global Sustainable Energy Solutions GSESwith its extensive experience in PV training, design and inspections, bzs regularly involved in discussions over practical methods that installers can use to implement the latest standards and guidelines.

In these installations, it is now possible for the installation to be completed without HD conduit. The IP4X rating requires the barrier to prevent penetration of objects with a 1 mm diameter or greater.

Description You will be required to comply with the following standards if you intend to design or install a solar photovoltaic system.

Modules deteriorating over time can then compound the difference. UV-resistant HD conduit – a good option for achieving compliant conduit throughout the PV installation.

Within 50 mm, an insulation barrier will be required. This is the most effective way to achieve compliant insulation barriers between AC and DC circuits. 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.

However, the version of the standard provides clarification that reduces the need for installing these cages.

This could lead to a potential hazard if the circuit is disconnected without adequate protection such as a load-breaking DC isolator. It will be difficult for barriers installed within enclosures to follow these requirements, unless purpose-made, compliant enclosures are used. Qs installed by Solar Powered Homes to achieve restricted access.

A code of practice is a set of rules which details how people in a ad industry should behave. 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.
