Although this may seem minor, not adhering to this can result in circulating currents between strings, even when the system is isolated. The latest version of the standard has reduced the scope of this requirement, providing a more practical method of achieving the desired protection. An example of this may be the use of cable trays.

Surge protection design philosophy. 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. 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 will save installers a lot of work, especially if they are already using HD conduit and installing isolators within enclosures with lockable flaps.

He has invaluable experience in assessing Australian PV standards and has provided technical consultancy services to regulatory authorities. Electrical services industry to experience long-term growth After a challenging past five years, the electrical services industry is expected to experience For DC-conditioning units, the voltage and current 503 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.


Installing AC and DC in the same enclosure, with a compliant insulation barrier, is difficult to achieve.

Australian Energy Storage Conference and Exhibition Uncertainty around fire emergency information signs has not been limited to DC-conditioning units and microinverter systems. SolarEdge power optimiser a DC-conditioning unit.

This could lead to a potential hazard if the circuit is disconnected without adequate protection such as a load-breaking DC isolator. UV-resistant HD conduit – a good option for achieving compliant conduit throughout the PV installation.

The IP4X rating requires the barrier to prevent penetration of objects with a 1 mm diameter or greater. 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. 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.

In many instances, this has resulted in installation of large cages around the inverter, isolators and cable runs Figure 3.

Code of Practice A code of practice is a set of rules which details how people in a certain industry should behave. In these installations, it is now possible for the installation to be completed without HD conduit.

The latest update includes several positive changes and clarifications but, xs with the release, the changes are minimal. 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.

Solar installation standard – how the recent changes affect you.

Nonetheless, DC PV cables within a building, but not within these cavities, need to be protected with medium-duty MD conduit. 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. The areas requiring HD conduit are now 0533 to those that are not clearly visible, specifically, ceiling spaces, wall cavities and under floors.

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.

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.

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.
