How much does the Enphase cost in 2026?
No Australian retailer we've checked publishes a fixed installed price for the Enphase, so treat any figure you're quoted as installer-specific and get it in writing. At 5 kWh usable, the federal Cheaper Home Batteries rebate is currently worth $1,357 off whatever price you're quoted (dropping to $1,117 once the factor steps down on 1 January 2027). Compare published prices for other brands at this capacity in our battery price guide.
