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 […]
The Pacific Perspective – The Energy Tri-lemma, Battery Storage in American Samoa and New Zealand Case Studies.
Last week Samoa held the Pacific Power Associations (PPA) 26th Annual conference in Samoa. As an allied member of the PPA and a Pacific training organisation, GSES attended the week-long conference. The Island Nations in the Pacific rely predominantly on diesel generators in large or micro-grid configurations for power supply. These Nations have turned to […]
Industry wide Improvement in Ingress Protection Safety Thanks to CEC Guidelines
Under the Renewable Energy Target (RET) requirements, solar photovoltaic (PV) power systems must be installed to relevant Australian standards and Clean Energy Council (CEC) guidelines in order to receive Small-scale Technology Certificates (STCs). To monitor this, the Clean Energy Regulator’s RET inspection program has been running since 2010 and the CEC review the outcomes of […]
The Blockchain Buzz
Over the past several months, there has been an increase in the amount of reference to Blockchain technology and what it can do for the renewable energy sector. Much has been written about this technology such as this article and this article. A number of global companies have even started to trial blockchain based energy […]
GSES Training: PV Gains a Further Foothold on Nauru
GSES has conducted PV system installation training on Nauru twice. The most recent training session was conducted by Dr. Rick Potter in November 2016.Nauru is a tiny island located just half a degree south of the equator and east of Papua New Guinea and the Solomon islands. The island is only 21 km² and one […]
Transition period ending for compliance to AS/NZS 4777.2:2015
The transition period for AS/NZS 4777.2: 2015 Grid connection of energy systems via inverters Part 2: Inverter requirements will end on the 10th October 2016, only 3 months away. The majority of inverters currently on the CEC approved product list currently expires on 9th October 2016. They will be removed from the list if manufacturers […]
A Practical Guide to PV Efficiency
At the end of June 2016, the world record for efficiency of rooftop solar modules was broken again: the US-based PV manufacturing company SunPower achieved an efficiency of 24.1% for a monocrystalline silicon-based PV panel, over 2% higher than the previous record. This news came shortly after the announcement earlier in the month of Hanwha […]
PV System Design: How to compete effectively in the wider market place
Commercial-scale PV systems present enormous opportunities for our industry. However, the requirements to source and verify a range of site-specific data over a large site is challenging. To then ensure this data correctly forms part of all aspects of the system’s performance and installation requirements can be complicated and unfamiliar to some system designers and […]
East West Arrays: Are they worth it?
The current cost of rooftop PV means that it can be cheaper to source your electricity from a rooftop solar system than buy it from the grid. A significant problem with this, however, is that people consume 50%+ of their electricity during the morning and evening when solar systems are not producing, is it possible […]
