Battery Glossary

Battery Storage
A system that stores electricity for use at a later time, such as in the evening or during a power cut.

State of Charge (SoC)
The current level of energy stored in the battery, shown as a percentage.

Charge Cycle
One full charge and discharge of a battery. Batteries are designed to handle many cycles over their lifetime.

Degradation
The gradual reduction in how much energy a battery can store over time.

Backup Power
A system configuration that allows a battery to supply electricity during a power cut.

Inverter
A device that manages the flow of electricity between the battery, solar panels, the home, and the grid.

Self-Consumption
Using electricity generated on-site rather than exporting it to the grid.

kW (Kilowatt)
A measure of power that shows how quickly electricity can be supplied or used.

kWh (Kilowatt-hour)
A measure of energy that shows how much electricity is stored or used over time.

Load
The amount of electricity being used by the home at any given time.

Depth of Discharge
How much of the battery’s capacity has been used during a cycle. Systems manage this automatically to protect battery health.

Thermal Management
Systems that control battery temperature to ensure safe and efficient operation.

Grid
The national electricity network that supplies power when battery or solar energy is not available.
