Solar Battery Comparison Chart
The following comparison charts list the latest lithium-ion battery systems available in Australia, North America, the UK, Europe and Asia from the world’s leading battery manufacturers. The tables include the most popular high-voltage and low-voltage (48V) DC-coupled batteries of the managed variety, plus self-managed lithium batteries for hybrid energy storage or stand-alone (off-grid) power systems. See our comprehensive home solar battery review for more details about lithium battery types and costs.

Solar Battery Systems (DC-coupled)
DC-coupled batteries are the most common type of battery used for home solar energy storage and must be connected with a compatible grid-connected hybrid inverter to create a solar energy storage system with backup power. Several modular battery systems, including low-voltage Pylontech and BYD batteries, can also be used for off-grid solar systems.
Off-grid Solar Battery Systems
The off-grid battery comparison table lists the well-known modular lithium battery systems generally used for large-scale off-grid and grid-connected energy storage systems. These are often referred to as self-managed batteries as they contain a BMS that monitors and manages the battery charging, temperature and cell balancing but do not require a communication connection (CANBus) to the inverter to operate. Learn more about off-grid battery systems in our detailed off-grid solar systems review.
Battery features and pricing explained
Features:
Weather ratings - batteries rated at IP20 to IP22 are suitable for indoor use only. Batteries rated at IP55 and above are suitable for protected outdoor areas. Note: Batteries should not be installed in direct sunlight.
Self-managed lithium batteries can be used as a drop-in replacement for deep-cycle lead-acid batteries and are compatible with most modern inverter-chargers used in off-grid and hybrid energy storage systems.
Battery cost estimates:
** The battery upfront cost estimate is based on various distributors and wholesalers. The cost does not include installation or any electrical alterations which may be required.
DC-coupled and off-grid battery prices do not include the cost of the inverter/s, isolators, fuses and other equipment required for safe operation.
Our detailed battery cost comparison article describes the estimated cost per kWh (per day) for some battery models.
NOTES:
* DOD and cycle life values estimated based on manufacturers specifications and rate of charge/discharge.
EOL = End of life: Typical EOF is when the battery capacity has reduced to 60 to 80% of the original capacity; learn more about the expected battery life and degradation rates in our detailed battery review.
