Battery Storage
Store your solar energy for use at night or during blackouts. Act before May 1, 2026: The federal battery rebate structure changes, reducing benefits for larger batteries. Currently ~$300/kWh on all sizes. Lock in maximum savings now.
Why Add Battery Storage?
Self-Consumption
Store excess solar during the day to use at night. Maximise the value of your solar investment.
Blackout Protection
Keep essential circuits running during power outages. Critical for areas with unreliable grid.
Time-of-Use Arbitrage
Charge from solar or off-peak rates, use during expensive peak periods. Save on high tariffs.
Virtual Power Plant (VPP)
Earn credits by sharing stored energy with the grid during demand peaks.
Battery Chemistry Types
Modern home batteries use lithium-ion technology, but different chemistries have different characteristics.
Lithium Iron Phosphate (LFP)
LiFePO4- checkLongest lifespan (6,000+ cycles)
- checkSafest chemistry
- checkBetter temperature tolerance
- checkNo thermal runaway risk
- closeLower energy density
- closeSlightly larger size
Nickel Manganese Cobalt (NMC)
Li-NMC- checkHigher energy density
- checkCompact size
- checkProven technology
- closeShorter lifespan (3,000-5,000 cycles)
- closeMore temperature sensitive

What Size Battery Do You Need?
Battery sizing depends on your evening/night energy usage and what you want to achieve. Here's a quick guide:
5-8 kWh
Cover evening usage for a small household. Lights, TV, fridge, basic appliances.
10-13 kWh
Most popular size. Covers overnight usage for average 3-4 person household.
15-20+ kWh
Large homes, high usage, EV charging, or extended backup during outages.

Federal Battery Rebate Ends May 2026
The Cheaper Home Batteries Program offers approximately 30% off eligible battery systems — but funding is limited and the deadline is approaching fast.
Why Act Before March 2026?
Installers are booking out months in advance. Early action ensures your spot.
The program may close early if funds are exhausted before May 2026.
Allow 4-8 weeks from quote to completion. Don't leave it until the last minute.
Frequently Asked Questions
helpHow long do home batteries last?
Most quality batteries last 10-15 years with proper use. LFP chemistry batteries can exceed 6,000 cycles, equating to 15+ years of daily cycling. Warranties typically guarantee 70-80% capacity retention.
helpCan I go completely off-grid with a battery?
Technically possible but expensive. You'd need a very large battery (30-50kWh+) and oversized solar to cover winter and cloudy periods. Most people achieve 80-95% self-sufficiency while staying grid-connected for backup.
helpWill a battery power my whole house in a blackout?
It depends on setup and battery size. Most installations back up essential circuits (lights, fridge, internet). Whole-home backup is possible with larger batteries and compatible inverters like Tesla Powerwall 3.
helpCan I add a battery to existing solar?
Yes! Batteries can be retrofitted to most existing solar systems. We'll assess your current setup and recommend the best approach - either AC-coupled or a hybrid inverter upgrade.
helpWhat is a Virtual Power Plant (VPP)?
A VPP aggregates home batteries to act as one large power plant. You can earn $300-$1,500+ per year by allowing the VPP operator to use a portion of your stored energy during grid peak demand.
