Home battery installation: costs and options
Decide what the battery needs to do first. Shifting daytime solar into the evening is a different job from keeping a fridge, modem and selected lights running in a blackout.
What to include in the scope
Compare usable energy in kWh, power output in kW, inverter compatibility and backup wiring. Request a cost for the complete commissioned installation and a breakdown of any inverter replacement, meter work and incentives.
Fixed electrical installations require a properly licensed electrician. Do not undertake DIY work on power points, switches, wiring or hardwired equipment.

Build your budget
Adjust the quantities and unit rates. This is a planning tool, not an installer quote.
Use local itemised quotes as the starting rates. Freight, labour availability and minimum call-out charges can change the total by location. Enter GST-inclusive rates where available and list removal, disposal and access separately when excluded.
Ask before you accept a quote.
- Which circuits will run during an outage, what reserve will remain, and what throughput or capacity limits apply to the warranty?
- Is GST included, and is the price fixed or estimated?
- Are removal, disposal, access and making-good included?
- What changes would trigger extra costs, and who approves them?
- What is the warranty on products and workmanship?
