Solar Battery Storage Comparison Table

Last Updated: 18th Nov 2019

Discover solar battery prices and system specifications with our regularly updated solar batteries comparison table. See which energy storage system may be best for your home or business.

info-icon 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.
 

New Feature: If a solar battery storage product comes in multiple capacities, click/tap the down arrow in the blue header to see and select available energy storage capacities and specifications for that system.

Note: Battery systems have been first sorted into three groups, based on whether an inverter is separately required, a system is “kind of” all-in-one or is all-in-one – and then alphabetically listed.

We plan to update this table frequently as more business and home energy storage systems become available, and specs and prices of existing solar batteries change.

Please note that system pricing is our best estimate of retail prices incl GST, unless specifically noted otherwise. But it is only an estimated cost.

Please read this if you are not 100% certain what a kWh is, or the difference between a kW (kilowatt) and a kWh (kilowatt-hour): What does kWh stand for?. It’s important to be clear on this.

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 figure provided.

For example, the Enphase AC battery has a total storage capacity of 1.2kWh. But as only 95% of that stored energy can be discharged (aka a 95% Depth Of Discharge) they battery’s usable capacity is really 1.1kWh.

Battery 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 system (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 home 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 solar battery and the best energy storage solution for you.

All In One Unit

This means the system includes batteries, a battery management system (BMS) and an inverter. The Sunverge SIS is one example of an all-in-one home energy storage system.

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 system until you have read the latest version of its warranty document sourced direct from the supplier. They change often and we can’t guarantee the linked version we provide above is the latest.

Total Warranted kWh (1 Cycle Per Day)

If you only discharge the battery once per day (most likely for larger solar batteries in residential situations) then the warranty period may expire well before the warranted kWh are all used up.

The number of kilowatt-hours (kWh) a home battery system can discharge per day is multiplied by the number of days in the warranty period in order to generate the figures for this row.

Cost Per Warranted kWh (1 Cycle Per Day)

This is the solar battery price (excluding installation) divided by ‘Warranted kWh (1 cycle per day)’. If you discharge the battery approximately once per day, this number indicates what energy storage system may be the most cost effective in your circumstances.

A Note On Battery Warranties

Some solar batteries in the table have different warranties for components within the unit. For example, some “all in one” battery storage systems warrant the batteries for 10 years but the internal inverter only has a warranty of 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:Although we try really hard to review the information in this comparison table up to date and accurate (and we update it regularly), mistakes could have been made and prices and other figures/specifications can go out of date quickly. Check with battery manufacturers before making any solar storage purchase decisions based on information provided in this table.
