How much do solar batteries cost in NZ?
Installed home battery prices in New Zealand mostly run between $7,500 and $20,000, depending on capacity and brand. Price per usable kWh usually improves as capacity grows: here the FranklinWH aPower 2 is the sharpest value at about $967 per usable kWh, the Enphase IQ Battery 5P the dearest near $1,600. Prices are indicative and exclude extras like a switchboard or backup wiring. For payback and how batteries compare with exporting to the grid, read our solar battery costs and payback in NZ guide.
LFP vs NMC: which battery chemistry lasts longer?
20 of the 24 batteries here use LFP (lithium iron phosphate). LFP handles more charge cycles than the older NMC chemistry, runs cooler, and copes with sitting at a full charge, which is why most warranties now reach 10 years or more. NMC packs more energy into a smaller, lighter box, so it still suits tight spaces. For a battery that cycles daily, LFP is usually the safer long term pick.
What size solar battery do you need?
A typical New Zealand home uses about 15 to 20 kWh a day. A 5 kWh battery covers the evening peak when power is dearest, and around 10 kWh starts carrying you through a full night on stored solar. Usable capacity here runs from 4.05 kWh (SolaX Triple Power T45) to 16 kWh (BYD Battery-Box LVS), and most solar homes land in the middle.
Which batteries keep the power on in a blackout?
Not every battery offers whole home backup: some only run essential circuits like the fridge and lights, and a few need a manual changeover. Continuous power here ranges from 2 kW to 12.8 kW, which sets how much you can run at once in an outage. If backup matters, check the backup capability and transfer type before assuming whole home cover.
How we verify these specs
Every figure here comes straight from the manufacturer's published datasheet, checked by hand. Where a brand does not publish a number, we mark it Not published rather than guess. Prices are indicative New Zealand estimates on one consistent installed basis, so the value per usable kWh stays fair between brands. Last verified 30 June 2026: spot something out of date?

Home battery FAQs
Of the 20 batteries on this page with a published NZ price, indicative installed pricing runs from $7,500 to $20,000. Value per usable kWh ranges from about $967 to $1,600. Your exact installed cost depends on your switchboard, inverter and installer.
No. A home battery can be added without solar, charging from cheaper off peak grid power and discharging at peak times. You get the most value pairing it with solar, but panels are not a requirement.
Both are LFP batteries with whole home backup options. The Powerwall 3 bundles its inverter into one unit, while BYD's Battery-Box range is modular, so you size it in steps to suit your home. Put them side by side above to see exact usable capacity, power and price.
Most batteries here carry a 10 year warranty, and a few (FranklinWH aPower 2, Enphase IQ Battery 5P, Qcells Q.HOME Core H5) go to 15 years. Warranties usually guarantee the battery keeps a set share of its capacity over that time. LFP batteries often outlast their warranty in normal daily use.
There is no single number: payback depends on your power price, how much you use and whether you have solar. Our solar battery storage guide works through the payback maths for New Zealand conditions.
Some can, some cannot. Whole home backup needs enough continuous power (here that goes up to 12.8 kW) plus the right backup wiring. Others only run essential circuits like the fridge and lights. Check the backup capability row before assuming full coverage.
