Franklinwh Apower 2 Cost: What You Will Pay in 2026
Written by HyreSolar Research Desk Price compilation from published, dated sources
The short answer
Franklinwh Apower 2 Cost depends mainly on system size, equipment and roof, and this page gives the installed range from dated, sourced quotes. Across 15 published, dated sources retrieved October 22, 2026, one aPower 2 installed with its aGate controller runs $15,000–$17,700 before incentives.
The aGate is required and is part of that figure; a second aPower 2 on the same aGate costs less than the first. No 30% federal credit applies to a system a homeowner buys: Section 25D ended for expenditures after December 31, 2025 (what changed).

What moves the price of a FranklinWH system
The aGate is the fixed cost. Every FranklinWH system needs one aGate, the controller that switches the home between grid, solar and battery and isolates it in an outage.
It is priced once, so the first aPower 2 carries it and each added battery does not. Ask for the aGate on its own line; a quote that buries it makes a second-battery price impossible to check.
Capacity comes in large steps. One aPower 2 holds 15 kWh usable and is rated for 10 kW continuous output, with a 15-year warranty, according to EnergySage's May 2026 review.
That output is enough to start a central air conditioner or heat pump, which is why it is often quoted for whole-home backup where a smaller battery would need load shedding.
Because capacity is added 15 kWh at a time, the next step up is a large one.
Electrical work moves it next. Whole-home backup usually means the aGate sits between the meter and the main panel, and an older 100 A service can force a panel or service upgrade.
The aPower 2 is AC-coupled, so it works beside most existing inverters, but the installer still has to fit it into the service.
Confirm the model on the contract as well: the earlier 13.6 kWh aPower and the aPower 2 can appear in quotes at similar prices.
Price by size and setup
| If your project is | Read | Why it differs |
|---|---|---|
| One aPower 2 with aGate | The range above | Includes the aGate, wiring, permit and labor. |
| Two or more batteries | Whole home battery backup | Added batteries skip the aGate; panel work may grow. |
| A retrofit to existing panels | Add a battery to existing solar | AC coupling keeps the existing inverter. |
| Comparing with Tesla | Powerwall 3 price | 13.5 kWh with a built-in solar inverter. |
| Smaller steps of storage | Enphase battery cost | 5 kWh modules instead of 15 kWh cabinets. |
How to check a quote
- 1Get the aGate on its own line
It is a one-time cost. Without it itemized you cannot price a second battery or compare against another brand.
- 2Confirm the exact model
The contract should say aPower 2 and state 15 kWh usable. The older aPower is a different product.
- 3Ask whether the service needs an upgrade
Whole-home backup on an older service is where quotes grow. The panel upgrade check shows what to ask.
- 4Register the warranty at install
Ask the installer to confirm registration in writing; the warranty terms depend on it.
