Understand how BESS stores electricity, supports solar generation and provides flexibility for Australian businesses and homes.
What is a BESS?
A Battery Energy Storage System stores electrical energy in rechargeable batteries. Depending on its configuration, it may charge from solar PV or from the grid and discharge when required.
How solar and batteries work together
Solar panels generate DC electricity, which an inverter converts into usable AC electricity. Available energy can supply building loads and, where suitable, charge a battery for later use.
Commercial battery applications
Battery storage may support increased solar self-consumption, selected peak demand management strategies and time-based energy optimisation. Savings are not guaranteed and depend on the site’s load and tariff structure.
Residential batteries and backup
Home batteries can shift solar energy into evening periods. Backup power during outages is only available where compatible equipment and the appropriate backup configuration have been installed.
Choosing the right system
Usable capacity, charging and discharging power, inverter compatibility, site conditions, safety requirements and energy consumption all influence system selection.
