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.

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.

Salt batteries – the only chemistry UL9540A certified for safety

More and more people are recognising that one of the major issues with energy storage batteries are the dangers with fires and explosions particularly associated with thermal runaway (self-sustaining fires). This has become particularly relevant as people are considering installing the many lithium ion battery technologies in their houses or businesses and are becoming aware of the possibility of the dangers associated with this.

Standards Australia has been working on new installation standards “AS-NZ 5139_2019” which will try and address this issue but there is still a lot of discussion around whether the new installation restrictions are too strict or are really looking at individual battery characteristics correctly and fairly.

International Standard “UL9540A” has been developed to independently examine Fire Risk with Battery Cells and Evaluate Thermal Runaway Fire Propagation in Battery Energy Storage Systems.
