GSES Delivers Solar Masterclass in Manila for New Energy Academy
We’re excited to share that GSES recently travelled to Manila, Philippines, to deliver a two-day advanced solar masterclass for New Energy Academy (NEA), one of the Philippines’ leading solar training providers. The event, part of NEA’s Training Partner Development Programme (TPDP), brought together solar training partners from across the country for an intensive programme of […]
TS 5398: Key Updates For Modular Battery Compliance in Australia
For a full overview of the standard update, read our dedicated article here. The SA TS 5398:2025 key updates for modular battery compliance build on concepts introduced under the Battery Best Practice Guide (BPG), but it introduces more structured requirements that directly affect how battery equipment compliance is assessed, particularly for modular and stackable battery […]
TS 5398 Overview: Australia’s New Battery Safety Framework
SA TS 5398:2025 overview establishes a new technical framework for battery equipment safety in Australia. As part of this shift, TS 5398 battery equipment safety Australia now plays a central role in shaping compliance pathways for battery OEMs. Why TS 5398 Matters Battery energy storage systems are rapidly becoming a more common feature of Australian […]
Consumer Energy Resources and Harmonic Distortion on the Grid
As the power grid evolves to accommodate more electronic, decentralised, and energy-efficient technologies, it gains flexibility and resilience—but also faces new technical challenges. A key concern emerging from this shift is harmonic distortion, particularly as it relates to the widespread use of Consumer Energy Resources (CERs). In this article, we explore what harmonics are, how […]
Solar PV System & Battery Energy Storage System (BESS) Thermal Imaging
Thermal imaging, also known as infrared imaging, is a powerful diagnostic tool in the inspection of Solar PV systems and Battery Energy Storage Systems (BESS). It captures and visualises temperature variations on a surface, allowing inspectors to identify hot spots, hot joints and irregular heat signatures that could signify electrical faults, failing components, or degraded […]
PV overcurrent protection changes from AS/NZS 5033:2014 to 5033:2021
The requirements for DC overcurrent protection seem to have changed a lot in the AS/NZS 5033:2021 update upon first glance. But most of these changes are just rearrangement and new notation. This article will explain the old and new requirements. Skip to: AS/NZS 5033:2014 requirements AS/NZS 5033:2021 requirements Comparison of AS/NZS 5033:2014 and AS/NZS 5033:2021 […]
Deep dive on the new AS/NZS 5033:2021 Updates
AS/NZS 5033:2021 Update – What You Need to Know As part of the solar industry, you’re probably accustomed to the 2014 version of the standard, which had two amendments published in 2018. In November 2021, this standard was updated to reflect the rapid growth of this industry and provide updated safety practices. Knowledge is power, […]
Moulded Case Circuit Breakers Explained
As installed system capacity continues to increase in the Australian PV market, it is valuable for system designers and installers to understand the mechanisms behind moulded case circuit breakers, and the meaning behind their ratings. A moulded case circuit breaker (MCCB) is a type of electrical protection device that is used to protect the electrical […]
Hacking the Battery Management System
First and foremost, it must be stated that GSES is very optimistic about the capability of new energy storage technology. GSES is confident that those that are involved in transition of the electricity grid are moving quickly to make new technology better, cheaper, safer and more secure. That said, a topic which has not been […]
