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+

15-20+ kWh

Large homes, high usage, EV charging, or extended backup during outages.

*Prices include installation. Federal rebate is approximately $302/kWh (2026 rate) before May 1, 2026. State incentives (WA, SA, NSW VPP) may provide additional savings.

10kW Solar Battery Price

A 10kWh battery is the most popular residential size, covering overnight usage for a typical 3-4 person home. After the federal rebate of approximately $3,300, expect to pay $4,700-$8,700 installed depending on brand.

infoPopular choices: BYD ($8,500-$14,000), Sungrow ($7,500-$10,500), Tesla ($15,000-$17,000)

6.6kW Solar System with Battery Price

A complete 6.6kW solar + 10kWh battery package typically costs $15,000-$22,000 before rebates. After federal solar STCs ($1,600-$2,800) and battery rebate (~$3,300), your out-of-pocket cost is approximately $9,000-$16,000 depending on location and equipment.

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.
