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.

An installer recently contacted us to talk about the performance of a SoNick battery he had bought 8 years ago.
Originally it was purchased as part of a portable trailer system. The battery was utilised in this capacity for a number of years. It was used to supply power in power outages and at events, as well as being used as a showcase of the SoNick battery and what could be achieved in a portable power system.
*** Note: not all batteries are suitable for use in portable power systems due to the risk of damaging their cells due to trailer movements and due to the risk of fire in case of accident or cell damage.
Due to the intermittent use of this trailer, the battery was often left to go cold between uses then heated up again when needed.

GridEdge is currently involved in a project to create a Renewable Energy Park at the Radial Timbers Sawmill in Yarram.
The project will establish a “Bioenergy Cell” that incorporates the GridEdge SoNick Battery Energy Storage System (BESS) and The Earth Systems Charmaker Pyrolysis Unit and solar installations.
Stage 1 of the Renewable Energy will be the installation of 2 installations of 100kW solar & 90 kWh battery storage on each of the 2 mills at Radial timber.
The battery installations are using 4 x 620V SoNick batteries in a SoNick Zebra container. Each battery installation is supported by an ELPower 100 KW PCS (power conditioning system).

This domestic installation was designed to run as a grid minimisation installation. Although the grid remains connected it is rarely used.
This is an area with frequent power outages, often for many days so the ability to have power in an off-grid installation when the grid wasn’t available was a major requirement.
Sodium Nickel Chloride (SoNick) batteries were selected as they have the highest energy density of any batteries and are completely safe with no off-gassing or fire risk, meaning there are no safety issues with installing the batteries. As the SoNick batteries operate with no temperature effects and no degradation from -20°C to +60°C there are no issues with either heat or freezing temperatures that are often experienced and the batteries don’t require air conditioning to keep them cool or heaters to heat them enough for them to work.
Lithium-ion batteries weren’t considered due to the difficulty in recycling lithium batteries at end of life and to their inherent fire risk.

Portable commercial office running in off grid situation.
Situated at a crushing plant used to crush concrete blocks for road fill. The portable office is placed near the weighbridge which didn’t have a grid connection to that particular part of site. Connecting to the grid was going to be very expensive and the portable off-grid hut was a perfect solution.
Battery usually discharges to around 50 – 60% capacity each day and is generally fully charged by 12 to 2pm each day.
Installation was easy as batteries could be installed anywhere in the office. As the SoNick battery doesn’t have any gasses given off no special enclosures were needed, unlike lead acid batteries which are what would have been used in this situation previously and would have needed a special room to contain gassing.

This domestic installation in rural South Australia was designed to run as a grid minimisation installation. Although the grid remains connected it is rarely used to power the house, although excess power is exported to take advantage of the feed in tariff available.
Before the battery installation this household had a 5 kW solar PV system installed with a Fronius solar inverter.
The battery installation was done in stages as requirements changed.
The original battery installation had one 9.6 kWh SoNick battery with 2 Victron 3 KVa Multigrid inverters and a Victron colour controller for communication.

This domestic installation was on a farm. Initially a portable trailer was purchased. This trailer was used to take out on the farm to provide lighting where needed. This trailer had 1 x 7.7 kWh SoNick battery, a 5 kVa Victron Multiplus inverter and 3 x 250W solar panels. 3 panels are not enough to keep the batteries fully charged depending on how much power is drawn from the batteries. The trailer was then plugged in to the household power supply to recharge the batteries.

It’s great to see the newest installation of the #SoNick batteries in Switzerland by Innovenergy.
This installation is a 540 kWh salt battery storage system and now stands in the basement of MIGROS Schlieren/ZH. The molten salt batteries are 620V SoNick batteries supplied by FZSoNick and inverters by Indrivetec.
The SoNick batteries are charged with a large 806 KW solar PV system.
The purpose of the large-scale project is to save energy costs by optimising self-consumption. The other benefit is to maximise peak shaving which ensures the supermarket doesn’t have a lot of intermittent high energy draws which would increase energy bills substantially.

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.
A space was identified under the stairwell as the only realistic place to house the batteries and inverters. This limited the type of battery storage due to both space and safety requirements. Continue reading “Medical Centre – Commercial Case Study using SoNick batteries”
