Franklin aPower 2 in Canada (2026)
Franklin aPower 2 lands at $14,000–$16,000 fully installed in Canada in 2026 for 15 kWh of usable LFP capacity. That's $935–$1,065 per usable kWh — the cheapest $/kWh of any mainstream Canadian residential battery, plus the longest warranty in market at 15 years. LFP chemistry at 95% depth of discharge, rated -20°C to +50°C operating temperature.

The clean sweep for Franklin on cost + warranty is why installers increasingly quote it as the default when a customer isn't locked into the Enphase ecosystem and doesn't need the integrated-inverter simplicity of Powerwall 3. The trade is you'll pay $2,000–$3,500 for a separate hybrid inverter if you're installing solar at the same time — that still nets below Powerwall 3 total cost on most install sizes.
Canadian installation notes
- Franklin requires Franklin Certified Installer credentials — ask for the installer's FCI number before signing. Fewer certified installers in Canada than for Tesla or Enphase, which can mean a 2-4 week wait outside major metros.
- Mounts indoors in a conditioned garage, basement, or utility room. Floor-stand or wall-mount both supported.
- Franklin SmartCircuits option (add $1,500–$2,500) adds per-circuit load shedding — useful for homes targeting whole-home backup instead of essential-loads-only.
- Backfeed on aPower 2 is 42A — exceeds the 32A headroom on a standard 200A panel under Canadian Electrical Code Rule 84-024 without workaround. Line-side tap or 400A upgrade typically required. See our 20% rule article.
- Monitoring via Franklin's FHP app. Less polished than Tesla or Enphase but covers the essentials — SoC, flow directions, 15-second resolution.
Franklin aPower 2 FAQs
How much does a Franklin aPower 2 cost in Canada in 2026?
expand_more
Franklin aPower 2 runs $14,000–$16,000 fully installed in Canada in 2026 for the single 15 kWh usable unit on a standard 200A residential service. That lands at $935–$1,065 per usable kWh — the cheapest per-kWh of the major mainstream residential batteries. The price includes transfer switch, permits, electrician labour, and commissioning. If pairing with new solar, add roughly $2,000-$3,000 for a separate hybrid inverter (Franklin doesn't have the integrated inverter Tesla Powerwall 3 does).
Franklin aPower 2 vs Tesla Powerwall 3 — which should I buy?
expand_more
Franklin wins on three dimensions: (1) cheapest $/usable kWh ($935 vs Tesla's $1,075); (2) 15-year warranty vs Tesla's 10 years; (3) LFP chemistry (safer in attached garage, longer calendar life, 95% DoD vs Tesla's 90%). Tesla wins when you're installing solar + battery for the first time — Powerwall 3's integrated hybrid solar inverter saves $3,000–$5,000 vs the external hybrid inverter Franklin needs. If you're adding a battery to existing solar, Franklin typically wins the total-cost math.
Does Franklin aPower 2 work in cold Canadian winters?
expand_more
Yes — rated -20°C to +50°C operating temperature. Most Canadian residential installs put the battery in a conditioned garage or basement where temperatures stay well above -20°C regardless. In unheated outbuildings (common on rural farm sites), the battery includes a self-heating function below -10°C that draws from stored capacity to maintain safe operating temperature. LFP chemistry is more cold-tolerant than NMC (Tesla Powerwall 3) in general.
What's the Franklin 15-year warranty actually cover?
expand_more
Franklin warranties the aPower 2 for 15 years OR 60 MWh throughput, whichever comes first. Capacity is guaranteed at ≥70% at the warranty endpoint. The 60 MWh throughput works out to ~4 full cycles per week for 15 years without triggering the warranty cap — well above typical residential cycling. Compare to Tesla Powerwall 3's 10 years unlimited cycles / 70% retention. Franklin's extra 5 years of coverage is a meaningful risk-adjusted value if you plan to stay in the home 15+ years.
Do I need a separate inverter with Franklin aPower 2?
expand_more
Yes — Franklin is AC-coupled and relies on an external hybrid inverter when paired with new solar. Add $2,000–$3,500 for a compatible string inverter (Sol-Ark, EG4, Deye are common Canadian pairings) if you're installing solar at the same time. If you already have solar with its own string inverter, Franklin AC-couples through an auto-transfer switch — simpler and cheaper. Powerwall 3's integrated inverter avoids this question entirely at the cost of less inverter choice.
Does the Clean Tech ITC apply to a Franklin aPower 2 install?
expand_more
No for residential — the 30% refundable Clean Technology ITC excludes residential owner-occupied homes. Yes for incorporated farm or commercial buyers using Franklin in business operations. On a $16,000 commercial install the ITC refund is $4,800. Franklin's commercial / off-grid / RV versions (aPower H, SmartCircuits) qualify when installed in business operations.
