The top batteries in Australia according to independent testing

Battery testing

At DC Power Co, we’ve developed two excellent value solar battery packages. One is for people adding solar panels and a battery to their home for the first time (Redback) and the other is for people adding a battery to their existing solar system (Sungrow). 

Both packages use battery technology that is being put through the paces in Australia’s first and only independent solar battery testing program: the Australian Lithium Ion Battery Test Centre.

In April 2020, the results of this program were released, and we’re proud to announce the technology at the core of both of our battery packages were top performers.


What did the testing involve?

Conducted over three years, the Australian Lithium Ion Battery Test Centre compared a number of lithium-ion battery chemistries and products available in the Australian market. It tested them under Australian conditions with the goal to provide consumers with independent and unbiased information on battery performance.

Throughout the test, each battery was cycled (that is, charged and discharged) three times each day. This meant that over the three year test period the performance of each battery would be expected to “degrade” like a 9 year old battery would at an average home.

The testing commenced in June 2016, with a second phase in June 2017 adding more batteries to the trial.

The test looked at:

  • Battery performance in a range of high and low temperatures
  • Reliability
  • Changes to battery storage capacity over time
  • Energy efficiency
  • Cost-effectiveness
  • Comparison of battery performance against manufacturers’ claims


The results

In the latest test report, the Australian Lithium Ion Battery Test Centre found only the Sony and Samsung battery packs were able to retain over 80% of their initial capacity after 2000 cycles with no replacements. Added later in the test, the Pylontech is also on track to achieve this result.

The test also identified five battery packages that have proven reliable and fault free:

  • Sony
  • Samsung
  • Tesla 
  • Pylontech
  • GNB Lithium

Our solar battery packages use this leading technology

Our Sungrow battery has Samsung SDI battery cells at its core, while our Redback Smart Hybrid System uses the Pylontech battery.

The testing found the Samsung battery pack (along with Sony) held over 80% of initial capacity after over 2000 cycles, which is the equivalent of six years. The Pylontech battery pack (which was introduced later during phase 2 of the test) is also on track to achieve a similar result.


Pylontech battery technology in our solar and battery package

Designed specifically for households adding solar panels and a battery at the same time, the DC Power Co solar and battery package brings Pylontech battery storage together with world-leading, tier 1 solar panels in one streamlined, cost-effective package. With financing options available, you can start saving with your solar and battery system now, and pay it off over time.

Samsung battery technology in our battery package

The DC Power Co Solar Battery Package is our powerful yet simple and affordable battery package that’s compatible with any existing solar system. Built using Samsung battery cells* and starting at just $6750 plus installation, it’s a modular battery package that comes with great warranties and blackout protection included at no extra cost.
