Why Sydney Fox ESS installs need a site-specific quote
Sydney homes can sit across Ausgrid, Endeavour Energy or Essential Energy networks, with different export limits and approval requirements. Your installed price also changes with the existing inverter, phase supply, switchboard, cable route and whether blackout circuits are included.
Fox ESS retrofit sizing
For an existing solar system, we size the battery around your post-solar evening consumption rather than your roof size. We check whether your current inverter can remain, whether AC- or DC-coupled storage is suitable, and whether your DNSP export limit needs approval.
