Battery storage is transforming how Hunter Valley homes use their solar energy. Instead of exporting excess power to the grid for a meagre 5-10c/kWh feed-in tariff, batteries let you store that energy and use it when electricity prices are highest — in the evening peak period when rates can exceed 40c/kWh.
Top Battery Systems for 2025
Enphase IQ Battery 5P
The Enphase system uses a modular approach — each battery unit provides 5kWh of usable capacity, and you can stack up to 4 units (20kWh total). Key advantages include:

NSW Feed-in Tariffs Make Batteries Essential
With NSW feed-in tariffs sitting between 5-10c/kWh while peak electricity rates exceed 40c/kWh, the economics of battery storage have never been stronger. Every kilowatt-hour you store instead of export saves you 30-35c — meaning a 10kWh battery can save $3-4 per day or over $1,200 per year.
