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.

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.

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.
