PRE RELEASE. Unlike many opinionated reviews, the Solar Review Battery Assessment Criteria compares the Soltaro All-In-One ESS Battery against the industries best known specifications.  The result, a solar battery review with no room for discretionary bias and the transparency you desire.  


Make and model:  Soltaro All-In-One ESS Battery.

Variants:  4.5 / 9.0 / 13.5 / 18.0 / 22.5 kWh.

  Warranty Cycle, Round-Trip Efficiency.


GREATER THAN 3.3 IS A VERY GOOD SCORE. The following content for the Soltaro All-In-One ESS Battery should be used as a guide only. Individual circumstances and compatibilities should always be taken into account when selecting the right solar battery for any given installation. This content has been built using the Solar Review Battery Assessment Criteria 1.0 based on available product specifications at the time of writing. 


Design is what defines a particular solar batteries versatility, base chemical makeup, and verification of defined parameters to assist greater value through innovation and advancement.

All-In-One Battery - Efficiency
  • 97% round-trip efficiency.


Performance in more ways than efficiency alone. How does a solar battery perform within its intended environment and in adverse conditions? The key specifications not often at first thought.

As guarantee obligations can often be shielded by installer incompetence, should a solar panel manufacturer define an adequately trained installer network with a complimentary warranty extension (added end-user benefit), such guarantee has been considered as a base warranty more likely of adhering manufacturer installation specifications.

Important: A manufacturers obligations under guarantee will be obsolete if the solar battery is not installed to manufacturer specifications. Use an authorised installer.

All-In-One Battery - Guarantee
  • 10-year warranty.
  • Parts & service warranty.

All well and good having the greatest technology, but what if that technology is simply out of reach for most? Adversely, the cheapest product may lack essential capabilities expected by many end-users. Put price into perspective. Affordability is where price and technology come together to help determine value.

How was the score for the Soltaro All-In-One Battery calculated? By utilising the Solar Review Battery Assessment Criteria V1.0 >


  1. Impressed with battery was going to have one of these installed but with the problem with the guarantee (having to be installed by a Soltaro engineer) I’ll give it a miss
