RCD Requirements for Backup Power from Solar PV Inverters
Some solar PV inverters offer a backup circuit that can be used even without the presence of batteries. This backup circuit offers the ability to power a small load, when the PV system is generating energy and when the grid is unavailable. Examples of these inverters include the following: 1. Fronius GEN24 Plus (with “PV […]
Using Solar and Battery Hybrid Inverters for Emergency Circuits: Managing the Neutral Connection
Solar and Battery Hybrid Inverters (also called Multiple Mode Power Conversion Equipment see AS/NZS 5139:2019 Introduction) are being used to power essential services (also called emergency sub-circuits, dedicated loads or selected loads) during grid outages. These systems allow a household or business to continue running critical services such as refrigeration, essential lighting, medical equipment, or […]
NSW Peak Demand Reduction Scheme: Essential Guide for Battery Installers
The New South Wales (NSW) Department of Climate Change, Energy Efficiency and Water (DCCEEW) [pronounced D’Queue by department personnel] introduced the Peak Demand Reduction Scheme (PDRS) in 2022. This scheme, which is administered by the NSW Independent Pricing and Regulatory Tribunal (IPART), uses a market-based mechanism to incentivise the installation and usage of energy efficiency […]
Understanding BESS Earthing Requirements in Electrical Installations According to Australian Standards
Earthing is a critical aspect of electrical safety in installations, ensuring that any exposed conductive parts are properly grounded to prevent electrical shocks or fire hazards. However, there is often confusion regarding the correct application of earthing requirements, especially when earth terminals are found unused in some installations. This document aims to clarify the circumstances […]
Understanding the 1000V Rule in AS/NZS 4777.1:2024
The latest update to the AS/NZS 4777.1:2024 standard introduces significant changes for residential solar installations, with one of the most notable being the new 1000V rule. This change allows installers to implement higher voltage solar systems in residential settings, but only if they strictly adhere to the updated compliance requirements. What is the 1000V Rule? […]
Habitable Rooms and Restricted Locations for Battery Installation
With the introduction of new battery rebate programs in Queensland and the ACT this year, and a proposed rebate in NSW expected in November, the safe installation of batteries has become an increasingly important topic. A common concern among installers is determining suitable battery installation locations, particularly regarding what constitutes a habitable room and a […]
Battery Location Restrictions from AS/NZS 3000:2018
The installation of Battery Energy Storage Systems (BESS) is governed by stringent safety standards as outlined in AS/NZS 5139:2019, specifically in sections 4, 5, and 6. These sections impose explicit restrictions on permissible installation locations to mitigate safety risks. In addition to the provisions specified within AS/NZS 5139:2019, compliance with AS/NZS 3000:2018 is also mandatory […]
New Accreditation Administrator Announced – Everything we know about Solar Accreditation Australia
The Clean Energy Regulator has just announced Solar Accreditation Australia (SAA) as the new installer and designer accreditation administrator! This means that the CEC is no longer the accreditation scheme operator, and the SAA accreditation scheme is now in effect. SAA is an independent, not-for-profit organisation founded by the Smart Energy Council and Masters Electricians […]
Solar Installation: Common Mistakes and Best Practices
In 2023 the Clean Energy Council suspended 166 accreditations and cancelled 51. Most of the cases opened came from the Clean Energy Regulator’s inspections program [1] which focuses on quality and compliance of installations across the country. GSES has been part of the Clean Energy Regulator’s inspection program for many years and has seen all […]
