Battery storage services across Sydney’s metropolitan area

Battery storage works by storing the excess solar energy from the PV system for usage when  your solar system isn’t at its highest output ( night time, early mornings and late afternoons).

With the increasing low rates solar owners receive for exporting their solar power to the grid, a battery can create more savings and sound investment by allowing us to store and use our generated energy, rather than export to the grid for a low rate, and buying it back for 3 to 4x times the amount in peak periods.

Another salient feature of storage systems is that it protects your house from power outages and helps reduce dependence on grid supply.

Battery Storage

Brief description of how solar battery storage works:

  • Solar Panels convert sun light to DC electricity
  • The inverter converts this to AC, which gets used by home appliances during the day time
  • The surplus power generated by the panels, which otherwise gets fed to the grid, is used to charge the batteries
  • Once the batteries are full charged, the remaining solar energy is exported to the grid as usual
  • The stored energy in the battery gets utilised during the night time and thus ensuring minimal dependence on the grid
