What a FranklinWH system actually is
FranklinWH is two products that only make sense together: the aPower 2 battery and the aGate controller that sits between your solar, the grid, the battery and, if you have one, a generator. Because the system is AC-coupled it does not care whose inverter is on your solar, which makes it the cleanest whole-home retrofit in this comparison. Each aPower 2 is a large single block with a high continuous output, and the aGate can manage a stack of them. The trade-off is that the controller is the product — a quote that treats it as an optional extra has misunderstood what you are buying.
- aPower 2 — Large single block, stackable behind one controller. AC-coupled LFP battery with its own inverter — the storage half of the system.
- aGate — One per home. The energy management center that integrates solar, grid, battery and generator, meters the home and sheds loads in an outage.
- Smart Circuits and generator input — Optional. Per-circuit control of critical loads, and a generator input so a portable or standby unit recharges the battery.
FranklinWH at a glance — sourced
- Current FranklinWH line-up in the US: aPower 2 (15 kWh usable). source
- FranklinWH is AC-coupled: it sits beside the existing solar inverter, which stays in place on a retrofit. source
- Usable capacity runs from 15 kWh to 225 kWh. source
- Capacity can be added later without replacing the inverter. source
- The manufacturer warranty is 15 years. source
- It works with inverters from other brands, not only FranklinWH's. source
- Listed models are certified to UL 9540, the safety standard permit offices and utilities check for home storage. source
A good fit in Houston if…
- Homes with existing solar that want whole-home backup without replacing a working inverter
- Households in outage-prone areas that want a generator folded into the same system
- Buyers who want load management and per-circuit control, not just storage
- Larger homes where one big block covers the evening peak and a second covers the outage plan
Look at something else if…
- You are buying solar and storage together and want the simplest single-box install
- You want capacity in small increments rather than large blocks
- You do not need whole-home backup and would rather not pay for the controller
- Wall space is tight — the block and the controller both need room
A FranklinWH in Houston performs exactly as well as its configuration — and the configuration is decided by whoever installs it.
Why the installer matters more than the battery
The hardware is rarely the problem on a bad battery install — the design, the panel work and the commissioning are. Installers are vetted before they join — typically 2+ years in business with a track record of decent reviews. Your Houston inquiry goes to 2-3 of them, and nobody else.
What specifically goes wrong on a FranklinWH install
- The aGate placement relative to the main service panel is the design decision that decides how much electrical work the job needs
- AC coupling means existing solar has to be metered through the controller correctly, or self-consumption never performs as modeled
- Load-shedding priorities configured wrong at commissioning leave owners surprised by what dropped during the first outage
- Generator inputs need a compatible generator and a transfer arrangement the installer actually designs, not a socket on the wall
- Large units need a solid mounting surface and a location that stays inside the operating temperature range
This is exactly what we vet for — get my FranklinWH quotes in Houston.
That's why FranklinWH quotes in Houston are only comparable when the scope matches. Here's what to hold constant.
Comparing FranklinWH quotes in Houston
We don't publish price bands, because installed prices move constantly and depend on your roof, service panel and utility. What we can tell you is what to hold constant so three quotes are actually comparable — match these first, then compare dollars per usable kWh.
- Whether the aGate is quoted as the core of the system or as an add-on — it is the core
- How many aPower 2 units, and whether the stack is sized to your outage plan or to your evening peak
- Whether generator integration is included, and what kind of generator the design assumes
- How your existing solar inverter is being metered through the aGate, which decides how well self-consumption works
- Panel work: whether the aGate replaces or sits beside your main service panel
A cheaper quote that skips backup hardware, assumes an inverter you don't have, or quietly changes the configuration isn't cheaper — it's a different job.

Battery incentives in Texas
- Residential Clean Energy Credit (IRC §25D) (federal) — The 30% federal tax credit for home solar and battery storage no longer applies to systems placed in service from January 1, 2026. What ended and what still applies
- Texas — no state battery program has been verified on this site yet. Ask each installer what Entergy Texas Inc. offers and to show the program page.
Still weighing a FranklinWH up? The Houston numbers and the deeper reading are below.
The Houston numbers
Most of Houston's 140 ZIP codes are on Entergy Texas Inc., an investor-owned utility regulated by the Texas utility commission, so its interconnection rules and rate plans are published and the same for every installer who quotes you. What differs is the crew: ask each FranklinWH installer how many Entergy Texas Inc. interconnection applications they have filed for FranklinWH systems, and to name the rate plan the battery is being sized against.
Entergy Texas Inc.'s residential rate averages about 13.7¢ per kWh on the 2024 OpenEI utility rate file — among the lower rates in the country. That shifts the case for a FranklinWH in Houston toward backup and toward whatever time-of-use or export terms Entergy Texas Inc. offers, rather than toward shaving a flat bill; an installer whose savings figure ignores that is not quoting Houston.
With 2,390,125 residents across Harris County, Houston is one of the largest battery markets in the country, and the FranklinWH installer pool is deep enough to be selective: prefer the crew that can show FranklinWH jobs on your utility and your kind of home over the one with the fastest quote.
NASA POWER's climatology puts Houston at 4.6 peak sun hours a day — solid solar territory, with a real gap between the best and worst months. Size a FranklinWH against the winter figure below, not the annual average.
Houston swings from about 6.3 peak sun hours in Jun to 2.6 in Dec — roughly 2.4× more generation in the best month than the worst. On a 10 kW array that is around 53.6 kWh a day in Jun against 22.1 kWh in Dec. Size a FranklinWH on the winter figure: FranklinWH is large blocks, stackable, so the honest question at quote stage is what it can actually refill on a 22.1 kWh day, not what it holds on paper.
Show month-by-month generation
| Month | Peak sun hours | 10 kW array, kWh/day |
|---|---|---|
| Jan | 2.9 | 24.7 kWh |
| Feb | 3.3 | 28.1 kWh |
| Mar | 4.5 | 38.3 kWh |
| Apr | 5.3 | 45.1 kWh |

FranklinWH vs Tesla Powerwall 3
- Where FranklinWH wins — A cleaner retrofit onto any existing solar, generator integration and load shedding in the base design, a larger single block with more continuous output, and a longer warranty framing.
- Where FranklinWH loses — No integrated solar inverter for a new install, more hardware on the wall, a thinner installer base than Tesla, and a system that is harder to justify if you only want a small battery.
We don't sell batteries, so we have no reason to talk one up.
What owning a FranklinWH is actually like
Spec sheets stop being interesting about a week after install. These are the things owners notice in year one.
- The app shows the whole home’s energy flow, not just the battery, because the aGate is metering everything — owners tend to use it more than a battery-only app.
- Generator integration is the feature owners in hurricane and wildfire country talk about most: the battery covers the short outages and the generator recharges it through the long ones.
- Load shedding means the system decides what to drop when the battery runs low, which is a comfort in an outage and something to configure deliberately on day one.
- The warranty is framed around energy throughput as well as years, so a household that cycles the battery hard should understand how that is counted.
Four questions to ask any FranklinWH quote
- Is the aGate in this quote, and where does it sit relative to my main panel?
- How is my existing solar being metered through the system?
- Which loads shed first when the battery runs low, and can I change that?
- If I add a generator later, what has to be true about it for the system to accept it?
Grid connection in Houston
- Entergy Texas Inc. interconnection — a battery in Houston needs an interconnection application with Entergy Texas Inc.. A good installer files it, confirms the UL 9540 listing on the exact FranklinWH model quoted, and flags any constraint in the quote — not after.
- Electrical permit and inspection — the install needs an electrical permit from the local permitting authority and an inspection before it is switched on. Ask whether permit fees and the inspection are inside the FranklinWH quote.
- Backup scope is a design decision — whole-home versus a backup sub-panel depends on your main service panel and the transfer hardware, not on the battery alone. Have the circuits that stay live listed by name on the quote.

FranklinWH questions, Houston answers
Does FranklinWH work with solar from another brand in Houston?
Yes — this is the main reason to choose it. The system is AC-coupled and FranklinWH states the aGate is compatible with micro- and string inverters from the major brands, so your existing solar keeps its inverter and the aGate meters it. Ask the installer to confirm your specific inverter model against FranklinWH’s compatibility list before you sign.
Is the aGate really necessary for a Houston home?
It is the product. The aPower 2 is a strong battery on its own, but everything that distinguishes FranklinWH — whole-home management, load shedding, generator integration, metering of your existing solar — lives in the aGate. A quote without one is quoting a different, lesser system.
Can FranklinWH work with a generator in Houston, TX?
Yes, and it is one of the strongest reasons to pick it in hurricane, wildfire and ice-storm country. The aGate has a generator input so a standby or portable generator can recharge the battery during a long outage, with the battery covering the short ones on its own. The generator has to be compatible and the transfer arrangement designed properly — ask for both in writing.
How many aPower 2 units do I need if I live in Houston?
One large block covers the evening peak and a short outage for most homes; a second is what turns it into a multi-day backup plan for a house with central air. The aGate can manage a stack of units, so you can start with one and add later. Ask the installer to size to your outage plan, not just your bill.
Is the FranklinWH aPower 2 UL 9540 listed for Houston households?
FranklinWH lists the aPower 2 as certified to UL 9540 and UL 9540A among its safety standards, which is what most permitting authorities and utilities require on a residential storage application. Your installer files the listing with the permit and interconnection paperwork.
Will FranklinWH run my whole house in an outage across Houston?
That is what it is designed to do, within the limits of your battery capacity. The aPower 2 has a high continuous output and the aGate sheds lower-priority loads as the battery runs down, so the house stays live on what matters. Whether it lasts through the night depends on how many units you have and what is running — ask for a load model, not a promise.
Do I need a FranklinWH certified installer in Houston?
FranklinWH runs its own certified-installer program, and because the aGate is doing electrical work at the service panel, you want someone who has commissioned several of them. Ask the crew how many FranklinWH systems they have installed and whether the aGate placement they are proposing is the one they have done before.
Who installs FranklinWH batteries in Houston?
We match your inquiry with 2-3 vetted installers serving Houston — typically 2+ years in business, with a track record of decent reviews, checked on state licensing and trading history, and carrying FranklinWH certification where they have it. You get 2-3 of them and nobody else does. Free for homeowners.
How do I compare FranklinWH quotes in Houston?
Installed prices move constantly and vary by site, so compare on dollars per usable kWh rather than headline totals — and only once the scope matches. For this brand the variables that matter are: whether the aGate is quoted as the core of the system or as an add-on — it is the core; how many aPower 2 units, and whether the stack is sized to your outage plan or to your evening peak; whether generator integration is included, and what kind of generator the design assumes. Get all three quotes on the same scope, then compare the installers harder than the numbers.
What battery incentives apply in Houston?
The federal Residential Clean Energy Credit ended for systems placed in service after December 31, 2025, so a 2026 FranklinWH install in Houston does not get the old 30% credit — a quote that still shows it needs re-pricing. No Texas battery program has been verified on this site yet; ask each installer what your utility offers and to show the program page, not a brochure line.
What does Entergy Texas Inc. need to approve for a FranklinWH in Houston?
A battery in Houston needs an interconnection application with Entergy Texas Inc. and an electrical permit from the local authority, and a good installer files both and flags any constraint in the quote — not after. What gets scrutinized depends on the configuration: the aGate placement relative to the main service panel is the design decision that decides how much electrical work the job needs. Ask the installer to confirm the UL 9540 listing on the exact model quoted, which is what the utility and the permit office check.
Are your Houston installers FranklinWH-certified?
Certification is one of the things we look at, and where a FranklinWH-certified installer covers Houston you'll see that in the match. It is deliberately not the only filter — a current certification says the installer has done the brand's training, not that they wire a good panel or come back in year three. Every installer serving Houston is vetted on the same bar set out above before they join. Ask the ones you're matched with what FranklinWH work they've actually done, and how much of it, before you sign.
Is a FranklinWH battery worth it in Houston?
Houston averages 4.6 peak sun hours, so a 10 kW rooftop array generates roughly 39.1 kWh on an average day — enough to cycle a FranklinWH on most days of the year. Texas runs its own grid, and the winter storm and summer peak events that have stressed it are the outages homeowners here plan around. Whether the bill side stacks up depends on what Entergy Texas Inc. credits for exported solar against what it charges you — Entergy Texas Inc. averaged about 13.66¢/kWh for residential customers in 2024 — so ask each installer to show that gap on your own rate plan.
