FranklinWH Battery Price 2026: Wholesale Buying Guide

FranklinWH battery pricing swings by volume tier, install type, and how the unit gets paired with existing solar hardware, so the number a licensed installer pays rarely matches what shows up in a residential quote.

This guide breaks down what actually moves franklin battery price at the wholesale level, which FranklinWH configurations make sense for which install type, and what to skip if you're pricing out a job in 2026.

TL;DR

FranklinWH battery pricing depends on unit count, stacking configuration, and whether you're buying the aGate smart panel alongside the battery — not a flat per-unit rate. For most residential whole-home backup jobs in 2026, a two-unit stacked configuration is the Buy, a single unit without the smart panel is a Consider for compact retrofits, and buying units without confirming inverter compatibility is a Skip. Sun Supply PV carries FranklinWH alongside Enphase, SolarEdge, Tesla, and REC at distributor pricing, and batteries and inverters ship free.

Why this matters

FranklinWH built its reputation on stackable capacity and a control system (aGate) that manages circuit-level backup instead of whole-panel backup, which changes the math on how many units a job actually needs. Pricing a job around a single unit when the load calc calls for two is the most common estimating mistake installers make with this brand in 2026.

Residential buyers researching franklin battery price usually start with retail comparison shopping, but the wholesale side of the market runs on different logic: volume tiers, freight terms, and whether the batteries and inverters ship free change the real landed cost more than the sticker price on a single unit.

Who this is for

This breakdown is built for two overlapping buyers: licensed solar installers pricing FranklinWH into a residential backup or hybrid solar job, and residential buyers doing a DIY or owner-supplied install who want to understand what drives the number before they get a quote. Both need to know the same thing — what specs actually change the price, and which configuration fits the load they're trying to back up.

What to look for in FranklinWH pricing for solar installers

Usable capacity per unit

Each FranklinWH aPower unit carries 13.6 kWh of usable capacity, and that number is the baseline every pricing tier scales from. Undersizing capacity on a whole-home backup job is the fastest way to get a callback in month two, so confirm the home's critical load before quoting unit count.

Continuous and peak output

A single aPower unit delivers roughly 5 kW continuous output with a higher peak rating for surge loads like well pumps and HVAC startup. Installers pricing a job with multiple high-draw appliances need to check whether one unit covers peak demand or whether the job needs a stacked configuration.

Smart panel compatibility

The aGate smart panel manages circuit-level backup instead of forcing whole-panel backup, and it's the piece that turns a battery purchase into a system. Pricing FranklinWH without factoring in the smart panel is pricing half the job — most installers underquote here in 2026.

Stacking limits

FranklinWH units are designed to stack, and knowing the maximum units per aGate matters when a residential buyer wants headroom for a future addition. Quoting a single unit for a home that will likely add a second unit within two years leaves both the installer and the buyer redoing the math later.

Warranty term

FranklinWH backs its aPower battery with a 10-year manufacturer warranty, which matters most to residential buyers comparing total cost of ownership rather than sticker price alone. A 10-year term is standard for lithium battery systems in 2026, so it's a baseline expectation, not a differentiator on its own.

Shipping and lead time

Batteries and inverters ship free through Sun Supply PV, which changes the freight line on a multi-unit order significantly compared to buying a single unit at a time. Availability on any given SKU is subject to change, so confirm current lead times before locking a client into an install date.

Top picks

Single aPower unit — the compact retrofit pick. 13.6 kWh usable capacity is enough for partial backup on smaller homes or targeted circuits. Consider this for retrofits where the client isn't backing up the whole panel.

Two-unit stacked configuration — the workhorse. Combined 27.2 kWh usable capacity covers most whole-home backup scenarios for average-size residential loads in 2026. Buy this configuration for standard whole-home backup jobs — it's the sweet spot most installers land on.

aPower plus aGate smart panel kit — the flexible pick. Circuit-level control means the homeowner can prioritize which loads stay powered during an outage instead of an all-or-nothing panel backup. Buy when the client wants selective backup control rather than blanket whole-home coverage.

Three-plus unit stacked system — the scale play. Multiple units on a single aGate cover larger homes or properties running higher continuous loads, but the price-per-kWh advantage shrinks past a certain unit count compared to simpler two-unit jobs. Consider only when the load calc genuinely requires it — don't oversize to pad the invoice.

Single unit without smart panel for whole-home backup — the false economy. Skipping the aGate to save on the quote forces whole-panel backup logic on a battery designed for circuit-level control. Skip this combination for any job billed as whole-home backup.

What to avoid

• Quoting battery capacity without confirming inverter compatibility. FranklinWH pairs with specific inverter setups, and pricing the battery in isolation from the inverter side of the job creates change orders mid-install.
• Assuming stock availability without checking current lead times. Availability shifts through 2026 — confirm before committing to an install date rather than promising a delivery window to the client.
• Treating warranty length as a differentiator. A 10-year warranty is the 2026 baseline across most lithium battery brands, not a reason to upsell a configuration the job doesn't need.

Verdict comparison

FAQ

What is FranklinWH battery price in 2026?
Wholesale FranklinWH pricing depends on unit count, whether the aGate smart panel is bundled, and current distributor tier — there's no single flat number. Contact a distributor directly for current pricing on the configuration you're quoting.

Is FranklinWH battery better than Tesla Powerwall or Enphase batteries for installers?
FranklinWH differentiates with circuit-level backup control through the aGate smart panel, while Tesla and Enphase systems have their own control architectures suited to different job types. The right fit depends on whether the client needs whole-home or selective circuit backup.

Does FranklinWH battery ship free?
Yes — batteries and inverters ship free through Sun Supply PV as of 2026, which changes the effective landed cost on multi-unit orders.

What's the FranklinWH battery warranty length?
FranklinWH backs the aPower battery with a 10-year manufacturer warranty, in line with industry-standard lithium battery terms in 2026.

Can residential buyers order FranklinWH directly, or only licensed installers?
Both licensed installers and residential DIY buyers can order FranklinWH batteries and system components at distributor pricing.

What's the difference between aPower and aGate?
aPower is the battery unit holding 13.6 kWh of usable capacity per unit. aGate is the smart panel that manages circuit-level backup and controls how multiple stacked aPower units distribute power during an outage.

How many FranklinWH units can be stacked on one system?
Multiple aPower units can stack on a single aGate smart panel, with the exact maximum depending on the aGate model and home's electrical setup — confirm the current spec sheet before quoting a large stack.

Does availability affect FranklinWH pricing in 2026?
Availability can shift lead times and freight costs on larger orders. Check current availability directly rather than assuming stock on any specific configuration.

One last thing

The detail installers miss most often: the aGate smart panel isn't an accessory, it's the piece that turns a stack of aPower units into a system that can prioritize which circuits stay live during an outage. Pricing a job around battery capacity alone and treating the smart panel as optional is how quotes come in low and installs come in over budget.

FranklinWH batteries ship free through Sun Supply PV alongside Enphase, SolarEdge, REC, and Tesla system components, all at distributor pricing for licensed installers and residential buyers.
