FranklinWH battery cost in Australia (2026)

FranklinWH sells a system rather than a standalone battery cabinet. Franklin Home Power combines aPower lithium iron phosphate (LFP) battery units with an aGate intelligent controller that manages grid, solar, battery, generator and EV charging paths and handles backup transfer during outages.

The most quoted Australian size in 2026 is the CEC-listed aPower X-01-AU at 13.6 kWh usable per unit, usually sold with an aGate X controller as one Home Power package. On our planning table, an indicative installed midpoint is about $15,500 gross for a single 13.6 kWh unit with aGate before rebates.

Real quotes often land between about $14,000 and $17,000 gross depending on backup scope, switchboard work, cable runs and whether multiple aPower units are stacked. Independent installer surveys in 2025-2026 often place FranklinWH near $1,100 to $1,150 per usable kWh before rebates - premium to modular DC stacks but in the same conversation as Tesla Powerwall 3 and sonnen on whole-home backup jobs.

The Cheaper Home Batteries Program discount is calculated from usable kWh at commissioning. On May to December 2026 modelling (~$252 per usable kWh on the first 14 kWh), a single 13.6 kWh aPower unit sits fully inside the best federal tier with no taper.

For 13.6 kWh usable, the modelled federal discount is about $3,427 (13.6 x $252). On our $15,500 gross midpoint, net cost before state incentives is about $12,073. The STC factor steps down from 1 January 2027. The same install later receives about $560 less federal support on our model unless hardware prices fall enough to offset it.

See our federal program guide for tier rules if you are deciding between late 2026 and early 2027 install dates. Commissioning date - not quote signature date - sets which STC factor applies.

State support changes the last few thousand dollars more than the Franklin badge on the cabinet. Starting from a typical $15,500 gross 13.6 kWh install with about $3,427 federal discount (2026 STC factor), modelled net before site extras:

FranklinWH marketing emphasises whole-home energy management through aGate rather than treating backup as an optional extra bolted on later. On many quotes, aGate is part of the Home Power package that coordinates sources and switches the home during outages.

Tesla Powerwall 3 quotes often show backup gateway hardware as a separate scope item - commonly about $1,500 to $3,500 gross depending on essential-circuits vs whole-home coverage. Franklin quotes may bundle more backup coordination into the base Home Power price, which is one reason gross midpoints can read higher than Powerwall before you compare backup scope apples to apples.

Neither brand delivers backup automatically without correct transfer hardware and circuit design. Ask each installer which circuits stay live in an outage, whether solar recharges the battery during a blackout, and whether generator or EV load paths are included in the aGate scope.

FranklinWH supports multiple aPower units on one aGate system for larger storage and heavier backup goals. Marketing materials describe scaling to many units on a single controller; most suburban quotes still start with one 13.6 kWh aPower X before adding a second unit.

Two 13.6 kWh units deliver about 27.2 kWh usable gross. Federal rebate taper applies above 14 kWh: only the first 14 kWh receives the full per-kWh discount; capacity from 14 to 28 kWh is discounted at 60% of that rate on our model. Two-unit gross quotes might land $28,000 to $32,000 before rebates with federal support well below double the single-unit discount.

Before upsizing to two Franklin units, run payback on a single 13.6 kWh stack and read our 13.5 kWh battery cost guide. Oversizing premium hardware when evening load fits one unit often lengthens payback even after rebates.

FranklinWH searches often overlap Powerwall-class size intent and modular 10 kWh value picks. Use the same gross-to-net logic on each quote rather than comparing one installer's headline net to another's pre-rebate price.

Tesla Powerwall 3 at 13.5 kWh and about $14,500 gross (~$11,100 net after 2026 federal) is the benchmark premium AC all-in-one on Australian searches. Franklin aPower at 13.6 kWh and about $15,500 gross (~$12,073 net) is often a few hundred to about $1,000 higher net on our midpoints while offering similar usable kWh.

Franklin can win when your priority is whole-home backup coordination through aGate and you prefer Franklin's system architecture over adding Tesla gateway hardware separately. Powerwall often wins on brand familiarity, installer network depth and slightly lower net on our table when backup scope is comparable.

Compare written quotes at the same usable kWh, backup circuits and retrofit path. Read our Tesla Powerwall 3 cost guide for gateway pricing and wait-time notes before you treat a bare Powerwall gross price as complete backup scope.

sonnenBatterie 10 at about $15,500 gross (~$12,980 net) and Enphase IQ Battery 10T at about $16,500 gross (~$13,955 net) sit in the premium AC tier with less usable kWh than a single Franklin or Powerwall on our midpoints.

Franklin 13.6 kWh at about $12,073 net often lands between Powerwall and sonnen on upfront net while offering more usable kWh than sonnen 10 or Enphase 10T. sonnen or Enphase can still win when your installer prices VPP integration cleanly or Enphase ecosystem lock-in reduces site friction on microinverter homes.

For bill-focused payback rather than backup narrative, compare Franklin against modular 10 kWh stacks in our best home batteries guide before you pay premium hardware prices.

Franklin aPower is AC-coupled through installer design with aGate managing grid and solar interaction. Many quotes target existing solar homes that want whole-home backup without a full DC hybrid inverter replacement, similar to Powerwall or sonnen retrofit conversations.

Existing inverter health, export limits and switchboard capacity still drive scope. A healthy string inverter may suit AC-coupled storage; failing or undersized inverters may push you toward hybrid replacement quotes from modular brands instead.

Western Australia state rebate eligibility for battery installs depends on approved inverter pairing in current scheme rules - confirm Franklin plus your inverter combination qualifies before you count stacked net cost on a WA quote.

Quotes should spell out aPower model and usable kWh, aGate controller model, monitoring app access, backup scope, and any switchboard or meter work. Franklin systems are sold through accredited installer networks rather than as a retail SKU you configure alone.

Federal STC discount should appear as a line item or be clearly deducted from gross price. State rebates (especially WA stacking) should not be assumed in net cost without eligibility confirmation.

Commissioning date determines which STC factor applies. If your quote assumes a 2026 install window, confirm that in writing before you compare against a 2027 scenario in the calculator.

The federal STC factor steps down from 1 January 2027. On 13.6 kWh the modelled discount falls by roughly $560. A $15,500 gross quote that nets $12,073 in 2026 might net $12,633 in 2027 unless the installer drops hardware price to compensate.

That does not mean every household should rush to install. Poor sizing, weak tariffs or unnecessary multi-unit stacks can wipe out the benefit of capturing the 2026 rebate. Model both years in the calculator if timing is open.

If 13.6 kWh is the right size for your evening load and backup goals, installing in 2026 captures better federal support on the right capacity.

Use this checklist when two or three Franklin Home Power quotes arrive. Mismatched backup scope is a common reason premium systems look cheaper or dearer than they really are.

Most accredited installers quote transparently, but these patterns suggest you should slow down and compare another quote or read our federal program guide before signing.

Run the homepage calculator with your state, bill and solar details at about 13.5 kWh planning size, then compare net cost and payback against our Tesla Powerwall 3 and 13.5 kWh battery cost guides at similar usable kWh. Toggle install year between 2026 and 2027 if timing is open.

When you request installer quotes, ask each to confirm usable kWh, aGate scope, backup circuits, and whether federal (and any state) rebates are already deducted. Match quotes to your state page for local rebate context.
