A renewable energy certificate will only be given where a nsz statement is provided by the installer of the unit that the installation complies with the following standards.

Cage installed by Solar Powered Homes to achieve restricted access. This article describes the key changes to the standard. AC and DC installed in separate conduit and enclosures. Modules deteriorating over time can then compound the difference. This article details the key updates and explains how they affect installers. In many instances, this has resulted in installation of large cages around the inverter, isolators and cable runs Figure 3.

While fewer areas will now require HD conduit, the change may not have a significant impact on PV installations in the domestic market. This means that, if conduit is fixed to a wall, the solar labelling needs to be facing out.

A solar photovoltaic system is a unit that converts energy from sunlight into electrical energy. A code of practice is a set of rules which details how people in a certain industry should behave. Surge protection design philosophy. 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.

Master Installer AS / NZS Update – Smart Energy Council

Although this may seem minor, not adhering to this can result in circulating currents between strings, even when the system is isolated. He has invaluable experience in assessing Australian PV standards and has provided technical consultancy services to regulatory authorities. Safety and Installation AS The latest version of the standard has reduced the scope of this requirement, providing a more practical method of achieving 5033 desired protection.

Code of Practice A code of practice is a set of rules which details how people in a certain industry should behave. Uncertainty around fire emergency information signs has not been limited to DC-conditioning units and microinverter systems. 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 nzx necessary.

As previously stated, one of the key drivers of updates to the standard is the introduction of new products to the industry.

This is particularly useful for installing on roofs with small areas facing different directions. Within 50 mm, an insulation barrier will be required. Although using only UV-resistant HD conduit increases the cost of materials, it increases the durability of the system sa may reduce the installation time.

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.

In addition to this, AC and DC switchgear cannot share the same mounting rail, unless it is constructed from a non-conductive material. Topics covered in recent GSES professional development days include commissioning, maintenance and fault finding; responding to solar tenders: For microinverter systems, displaying these ratings is generally not necessary as the voltage aas usually the same as for other AC electrical systems VAC.

Therefore, installers upgrading old systems with new parallel strings need to pay particular attention to this requirement.

Solar installation standard – how the recent changes affect you

This is the most effective way to achieve compliant insulation barriers between AC and DC circuits. This requirement was introduced with an aim to reduce the risk of short circuit by providing additional mechanical protection. You will be required to comply with the following standards if you intend to design or install a solar photovoltaic system.

However, it will be difficult to demonstrate adequate protection – so, a safer alternative would be to adhere to the same requirements as domestic installations. Signage Uncertainty around fire emergency information signs has not been limited to DC-conditioning units and microinverter systems. 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.

Furthermore, the labelling needs to be visible. 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.

An example shutdown procedure has also been displayed in the standard.

Electrical services industry to experience long-term growth After a challenging past five years, the electrical services industry is expected to experience As DC-conditioning units and microinverters have unique electrical characteristics, it has been unclear how they should affect ae labelling and signage displayed.

GSES also provides professional development days at locations around Australia, which give 503 the opportunity to achieve the annual requirement of CPD points in a single day. 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.

Nonetheless, DC PV cables within a building, but not within these cavities, need to be protected hzs medium-duty MD conduit.

It further specifies that the earthing cable from the array frame can be connected to the AC earth conductor at the inverter.
