Solar Battery Storage Comparison Table
Last updated: August 2017
Discover battery prices and specifications with our regularly updated solar batteries comparison table. See which energy storage system may be best for your home or business.
 |
Hit 'Expand' for fullscreen. Scroll within the table to see all the rows and columns. See notes below the table. Any corrections, additions or feedback? Email us. |
We plan to update this table frequently as more products become available, and specs and prices of existing solar batteries change.
Please note that pricing is our best estimate of retail pricing incl GST, unless specifically noted otherwise. But it is only an estimate.
Please read this if you are not 100% certain what a kWh is, or the difference between a kW and a kWh: What does kWh stand for?
Usable Storage Capacity (kWh)
The energy stored in a solar battery system that can actually be used. In most cases this is less than the nominal storage capacity.
For example, the Enphase AC battery has a total capacity of 1.2kWh. But as only 95% of that stored energy can be discharged (aka a 95% Depth Of Discharge) its usable capacity is really 1.1kWh.
Power (kW)
A solar battery's power is how fast it can be charged or discharged.
For example, an Enphase AC battery is a low power battery (also known as an 'energy' battery) because it takes 4 hours and 23 minutes to discharge all its usable energy, while the BMZ ESS is a high power battery because it can discharge all its usable energy in under 40 minutes.
A high power battery system isn't necessarily more desirable than a low power battery - your household's unique energy usage needs will determine how much power you will require from a battery and the best energy storage solution for you.
All In One unit
This means the system includes batteries, a battery management system, and an inverter. The Sunverge SIS is one example.
If a battery management system and/or inverter have to be purchased separately this will add to the total cost of the system.
Warranty Document Supplied?
Links to a warranty document if it is available. Don't buy a solar battery until you have read the latest release of the warranty document direct from the supplier. They change often and we can't guarantee the linked version is the latest.
Total warranted kWh (1 cycle per day)
If you only discharge the battery once per day (most likely for larger batteries in residential situations) then the warranty period may expire well before the warranted kWh are all used up.
The number of kWh the battery system can discharge per day is multiplied by the number of days in the warranty period to get the figures for this row.
Cost per warranted kWh (1 cycle per day)
This is the price of the solar battery divided by 'Warranted kWh (1 cycle per day)'. If you discharge the battery approximately once per day this number indicates which system may be the most cost effective.
A note on warranties
Some products in the table have different warranties for parts within the unit. For example, some "All in one" units warrant the batteries for 10 years but the internal inverter for only 5 years.
We use the 'weakest link' warranted figure (so in the above example, 5 years instead of 10 years) when calculating the cost per warranted kWh.
Disclaimer: We are only human. Although we try really hard to keep this table up to date and accurate, mistakes could have been made and prices and other figures can go out of date quickly. Check with the manufacturers before making any purchase decisions based on information provided this table.
