What Does a Home Battery Actually Do?
Use your own power at night
Most solar is generated between 10am and 3pm — when most households aren't home. A battery stores that energy for when you actually need it: evenings, mornings, and overnight.
Stay on during blackouts
When the grid goes down, a battery-equipped home can keep running automatically — lights, fridge, Wi-Fi, and medical equipment — for hours or through the night, depending on capacity.
Cut your bills further
With time-of-use tariffs, charging a battery overnight at off-peak rates (and discharging at peak) can shave your grid costs even on days with little sun. Every kWh you make and store is one less you buy.

Battery Rebates We Apply for You
Two incentives reduce the cost of home battery storage — and Supply Solar confirms your eligibility and handles all the paperwork.
Cheaper Home Batteries Program (Federal)
The Australian Government's battery rebate, launched 1 July 2025, provides a subsidy on eligible home battery installations — significantly reducing the installed cost for qualifying households. Supply Solar assesses your eligibility and applies the rebate directly to your installation.

What Melbourne Homeowners Say
"Had a GoodWe ESA retrofitted to our existing 10kW system. Supply Solar checked inverter compatibility first — the AC-coupled design meant we kept our current inverter. Install was clean and the battery went live the same day."
"Went with the Sungrow SBH as we already had a Sungrow inverter. The team explained everything — including the federal rebate — and the quote matched the final bill exactly. No nasty surprises."
"We did 13kW solar plus a Sigenergy SigenStor battery as a package — and we're planning to add their EV charger next. Supply Solar handled both rebates and sorted the grid approval. Our evening usage is now almost entirely from the battery. Very happy."
