People install battery systems for many reasons and likewise people choose battery technologies for various reasons.
For many years people have used lead acid batteries as a known battery technology, particularly in off grid installations. A battery of choice has often been used Telecom batteries which are replaced regularly from telecom installations that need guaranteed UPS (uninterrupted power supply) capabilities. As these batteries are often sold at a vastly reduced cost it is economical for off-grid households to add a large number of batteries to an off-grid system to allow for reduced capacity of the batteries.
Unfortunately, for lead acid battery systems the battery system operates at the capacity of the weakest battery so you are unable to use new lead acid batteries in older systems and would need to replace the whole bank of batteries when more capacity is needed.
Lead acid batteries are well known for having a “falling off the cliff reputation” and degrading very suddenly and quickly, often with no warning. This happens particularly often in cold or hot weather. Coincidentally this is often when batteries are needed the most for heating and cooling. At the same time, most people who live off grid have learnt to manage their electricity usage to only use what is available and to use a generator when batteries are unavailable.
If you’re serious about battery safety, one battery stands head and shoulders above all other battery technologies.
It’s the Sodium Nickel (SoNick) salt battery, manufactured by FZSoNick and distributed in Australia by GridEdge.
With increasing demands for battery safety standards, SoNick is a unique product that helps our partners stand out.
The SoNick battery technology was the first and still is one of very few that have UL9540A certification for safety, stating it will not go into thermal runaway, both on a cell and complete module basis. This means no risk of fire or explosion, even in the presence of external fire.
As we move towards a future that heavily relies on renewable energy sources and sustainable technologies, energy storage solutions play a crucial role. Molten salt batteries, also known as liquid metal batteries, have emerged as a promising option due to their unique characteristics and advantages. They are a type of rechargeable battery that uses molten salts as the electrolyte. Here are some of their benefits:
Enhanced Safety: Molten salt batteries generally have good safety characteristics. Safety needs to be a paramount concern when it comes to energy storage systems. Molten salt batteries excel in this aspect due to their inherent design. These batteries use metal electrodes and a molten salt electrolyte, which eliminates the risk of thermal runaway or explosions associated with some other battery chemistries. The materials used in molten salt batteries are non-flammable and non-toxic, making them inherently safe and reliable. The fact that molten salt batteries use non-flammable and non-toxic salts, further enhances their safety profile.
#SMC batteries perform outstandingly even in one of the hottest regions of the Earth! As part of a joint activity with the end user, 32 modules of SMC batteries (272kWh) installed outdoor in Saudi Arabia have been constantly monitored during the summer period. Background: 👉July 2020-December 2021: batteries remained at stock for 17 months before the installation (no refresh charge necessary). 👉December 2021: installed in an outdoor shelter without Air Conditioning and ventilation. 👉January 2022–today: monthly capacity tests were performed to check for any energy variation. FZSoNick Group are glad to share the excellent results achieved so far.
Reef HQ aquarium was looking to add energy storage batteries to their recently upgraded PV system. One requirement of the battery storage was for it to be as environmentally friendly as possible.
Reef HQ, near the Great Barrier Reef is a large saltwater aquarium with a strong sustainability ethos. The Aquarium is the world’s largest living coral reef aquarium and has many impressive exhibits, showcasing rare and extraordinary features of the Great Barrier Reef .
The medical centre was to be refurbished and part of the upgrade was to install a PV system with battery storage. The difficulty was allocating the space for battery storage that was safe for patients as well as staff. As is usual in a medical centre space is a premium and is used for medical related purposes as a priority.
For many businesses it is important to look at using battery storage to reduce peak demand charges. Often, even one large energy spike can greatly increase total energy bills with this drawdown increasing the energy charge for all power usage. If the peak demand needed can be reduced then the overall electricity charges can be reduced.
Peak demand usually occurs when several high energy using pieces of machinery come into use at the same time, particularly if this machinery has large initial starting energy draws.
Peak demand is usually calculated based on the highest 15 minute average usage over a given month, even if it only occurs once a month (some energy retailers actually use the maximum usage over a yearly period, again even if this maximum only occurs once a year). These demand charges are also often charged on a tiered scale with higher charges the higher the peak is.
GridEdge is a company that delivers both off grid and on grid energy supply to all levels of consumer demand.
GridEdge has the Australian and New Zealand distributor rights to the FZSoNick sodium nickel chloride battery which has superior operating capabilities, compared to any other battery technology, currently available. The SoNick battery operates at a wider range of temperatures compared to other batteries and has the advantage of being a non-toxic, environmentally friendly battery that is much more compact, compared to many other batteries set up currently on the market or proposed in the near future.

On June 14, 2016, four researchers at the NASA Jet Propulsion Laboratory were preparing to ship a waist-high, ape-like robot named RoboSimian off-site. The robot had been built to rescue people from dangerous situations that were to difficult for human rescuers. The scientists swapped one lithium-ion battery for a fresh one, then left for lunch to let the new power supply charge.
Unfortunately, the new lithium ion battery malfunctioned and went into thermal runaway. Luckily the researchers were no longer in close proximity to the robot so no-one was hurt, although NASA have said there have been a number of these close calls.
Just like GridEdge’s sodium nickel chloride battery technology Redflow’s flow battery is well suited to Australia’s varying weather conditions and doesn’t have the fire risks that lithium ion batteries do.
