Understanding Solar Battery Specifications

Capacity - How much energy the battery can store, usually measured in kilowatt-hours (kWh).

Depth of discharge (DoD) - The amount of energy that can be safely used without accelerating battery degradation. 

Power - How much power (in kilowatts) the battery can deliver. 

Efficiency - How much electricity the battery will actually store and put out again. 

The total number of charge/discharge cycles - How many cycles of charge and discharge the battery can perform before it's considered to reach the end of its life.

Lifespan (years or cycles) - The expected life of the battery (and its warranty)

Ambient temperature range - Operational temperature of the battery.

Tesla Powerwall Capacity

The Tesla Powerwall is a 14kWh battery with 13.5kWh of usable energy storage.

The Powerwall uses lithium NMC (Nickel-Manganese-Cobalt) battery cells developed in collaboration with Panasonic which is similar to the Lithium NCA cells used in the Tesla electric vehicles.

The Powerwall has an integrated AC-DC inverter-charger, which boasts a continuous output of 5kW and a peak output of 7kW.

The power output is generally well suited to meet the requirements of an average home, which often has several high powered appliances running simultaneously.

Tesla Powerwall Lifecycle and Warranty

The Powerwall warranty is 10 years with 70% minimum retained capacity.

However, if charged using solar plus low tariff (off-peak) energy, then the number of 'daily' cycles could be greater than one and this can increase cell degradation.

The total amount of energy measured at the battery AC output is 37.80 MWh. This equates to roughly 80% of the battery capacity, or 10.5kWh, being discharged every day of the year.

This guarantees the battery will retain at least 70% of its original capacity either after a 10-year period or after a certain amount of energy throughput which is 37.8MWh for the Powerwall.

Tesla Powerwall Blackout Protection and Monitoring

The Tesla Powerwall uses an additional Backup Gateway to enable blackout protection.

In the event of a blackout, it isolates the backup circuits from the electricity grid and enables the system to function in off-grid mode.

The gateway also provides advanced monitoring options and time-based controls.

About Tesla

Tesla, Inc. was founded in 2003, originally as Tesla Motors. Tesla is headquartered in the USA's San Francisco Bay Area, with office locations around the world (including Australia).

After cutting its teeth on electric vehicle development, Tesla then expanded into commercial and home battery storage.

The company arrived on the home energy storage scene accompanied by great fanfare with the Tesla Powerwall battery back in 2015, which was followed by the Powerwall 2 in 2016.

The Powerwall is produced in the Tesla Gigafactory in Nevada USA.

Understanding your Solar Energy System

There are three core elements to a complete residential solar energy system:

  • Solar Panels capture sunlight and convert it to electricity.
  • Solar Inverters manage the converted electricity to your home or the grid.
  • Solar Batteries store excess solar electricity generated by your panels.

You can learn more about each of these components in the guides to help you decide on what type of solar setup is most suitable for your home.
