Solar & batteries in Mortdale 2223.
A battery only earns its place when the numbers work for the household using it. In Mortdale and across the inner south west, our engineers model solar generation against your real consumption data before recommending a system size, so 2223 designs are built around evidence rather than assumption.
Also covering Oatley.
01Local context
Solar & storage in Mortdale & the inner south west.
Inner south west
The inner south west combines post-war brick residences, expanding granny-flat and dual-occupancy stock, and a substantial light-industrial base. Roofs are generally simple and well-oriented, good fundamentals for solar, while multi-dwelling sites raise metering questions that need to be settled before any equipment is specified.
Adding a battery to existing solar in Mortdale is often the highest-value upgrade available, but it depends on the age and type of the existing inverter. We assess whether AC coupling, a hybrid replacement or a staged upgrade makes more sense, and say so plainly when the honest answer is to wait.
Climate
Away from the coast, summer afternoons run hot and still with strong air-conditioning demand, and winter mornings are cool enough to matter for heating loads.
02Network
Your local distributor.
Ausgrid (indicative)
Sydney's north, east and inner suburbs, the Central Coast and the Hunter are generally served by Ausgrid. Connection approvals, inverter capacity limits and export arrangements are set by the distributor at your connection point, and they differ between single-phase and three-phase supply. We confirm the current rules for your address before finalising a design, never assume the limits that applied to a neighbour's system still apply.
03What we deliver

04Common projects
What we typically design in the inner south west.
Rooftop solar on post-war and project residential properties
Batteries paired with existing solar systems
Metering design for dual occupancies and granny flats
Commercial solar on light-industrial roofs
Esena works across the inner south west with one consistent method: assess the site, engineer the design, then install and support it for the long term. For Mortdale properties that means a recommendation grounded in your actual usage and local network conditions, with program eligibility confirmed, not assumed.
05Incentives
Programs that may apply in New South Wales.
Peak Demand Reduction Scheme (PDRS)
A NSW Government scheme that may provide incentives for eligible battery energy storage system (BESS) installations across residential, apartment and commercial pathways. Subject to eligibility and current program rules.
Federal Cheaper Home Batteries Program
From July 2025, an STC-style upfront discount applied by your installer, scaled to battery capacity and subject to eligibility criteria. Indicative only, confirm current settings with an accredited installer.
