What extended power outage teaches us about backup battery power

Recently, after the severe weather event that hit Victoria on 9th June the ABC wrote an article comparing how a few different battery installations performed.

https://www.abc.net.au/news/2021-07-03/battery-power-dandenong-ranges-tesla-agm-grid/100264988

This article pointed out the importance of when purchasing an energy storage battery that it is fit for the purpose that you want it to provide.

Just like many people don’t initially realise that solar arrays don’t operate if the power is disconnected, battery storage systems don’t always work either.

This is fine if you just want a battery energy storage system to provide some load sharing but if you want power when the grid is disconnected the battery has to be capable of being used in an off-grid situation and it has to be wired to allow for this. This usually means the battery inverter is wired in before your solar inverter so that the complete battery and solar PV energy system can operate independently from the grid.

The type and size of your battery system is also important and how much of a battery systems capacity is actually useable. With lead acid and AGM batteries, generally only 30 – 50% of the batteries capacity is useable which means you will need a larger system capacity overall. Also as lead acid and AGM batteries tend to degrade over time and with use this needs to be taken into account when sizing your energy storage system.

Protect Yourself from power outages from wind and storm damage

Windy winter weather tends to bring trees down on power lines, cutting off your power supply as many people in Victoria have discovered recently. Many people in Gippsland and the Dandenongs are still without power a week after the storm that raged across Victoria on 9th June.

For many people the need to protect themselves from power outages is becoming a more and more common occurrence and it is not unusual for it to take days for the power to be reconnected, particularly if you are not on a main line and other lines take priority.

Yarram Circular Economy event – GridEdge report

Recently GridEdge was part of the Yarram Circular Economy event on 23rd May 2021, hosted by Yarram Community Energy. GridEdge in conjunction with Regenerative Resources are working to set up a Renewable Energy Park at the Radial Timbers Sawmill in Yarram with the first stage involving a pyrolysis unit supported by a SoNick battery storage system.

Renewable Energy Park at Yarram Sawmill

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 Pyrotech Energy Mobile Pyroflash Plant Pyrolysis Unit.

Stage 1 of the Renewable Energy Park is to establish a small 2-tonne pyrolysis unit plus SoNick battery storage

Stage 2 will be the installation of 100kW solar & 67.5 kWh battery installation that will be shared with a Yarram community group via a benefit sharing model.

Stage 3 will be the installation a 10-tonne pyrolysis unit plus additional SoNick battery storage

Stage 4 will be the installation of a neighbourhood battery to provide energy for the wider Yarram community.

Recyclable batteries that do not require maintenance – FZSonick

A chat with Giovanni Zola, General Manager of FZSonick SA of Stabio: the only company in the world that manufactures and markets accumulators (batteries) with the innovative sodium-chloride technology. The same have various fields of application. Let’s find out which ones.

FZSONICK was born from the historical passion of the Dolcetta family for the world of energy which, since the early 2000s, began to take an interest in green batteries. In 2010, following the agreement signed with the Swiss company Mes-Dea, manufacturer of the same type of batteries known as “Zebra”, the current company was born that markets accumulators with the innovative Nickel Sodium Chloride technology commonly also called “Salt Batteries”. For the moment FZSONICK is the only company in the world to produce batteries with this technology. The company is present in Stabio, Switzerland, with a production plant and a research center; in Italy (in the province of Vicenza), it has a sales office as well as in North America (in Elgin, Illinois) for worldwide distribution. With its product lines, FZSONICK currently serves 3 reference markets:

Battery safety and fire risk

When installing energy storage batteries more people are becoming aware or the risks associated with batteries that have a possibility of going into thermal runaway.

Over the last few years there have been a number of reports of fires and explosions being caused by lithium ion batteries.

‘Zombie batteries’ causing hundreds of waste fires, experts warn

Emergency energy storage to Protect Yourself from bushfire power outages

During bushfires power is often lost to many areas and sometimes is not returned for days or weeks at a time. At these times communities often have to rely on generators, especially if, as in the devastating 2019-2020 Australian bushfires roads are cut off to complete communities for extended periods of time.

     Emergency Problems

  • Bushfires and other emergencies cause loss of grid electricity
  • No power for communications
  • No power for medical and other health supplies
  • No power for food storage fresh or frozen
  • No power for pumps for clean water
  • Inability to power petrol pumps for fuel for emergency evacuations

     Solution – Earthworker Emergency container

  • Can supply emergency power
  • Uses safe non-flammable SoNick battery technology
  • Can be setup in short period once on site
  • Can be powered by solar, wind or diesel backup
  • Can be configurable to suit application
  • Can be delivered by plane, helicopter, truck or boat.

Not all battery inverters are equal

With the installation of energy storage systems most people look at the battery and concentrate on that but in reality the battery inverter is an integral part of any energy storage system and will dictate much of the energy storage systems operations.

Often when an energy storage system isn’t working properly the fault lies with the inverter and not the battery.

Inverter power is measured in kVA or volt amps.

The battery inverter takes power from the solar PV array (solar inverter or MPPT) and battery which can be of different voltages and converts it to 240V for household of business use.

Solar inverters are designed to work with solar PV arrays and battery inverters are designed to work with energy storage batteries. Hybrid inverters are also coming onto the market that combine both solar PV and battery conversions.
