The facts that change the ownership choice

Each line carries its own check date because price, software, specifications, and product cycle do not age at the same speed.

QuestionCurrent answerFreshnessBasis

Current price

$17,655 current typical installed reference

Treat this as a national installed quote benchmark, not FranklinWH MSRP; preserve aGate version, service work, backed-up loads, generator controls, permits, utility, installer labor, tax and any solar scope

Checked 5 days agoOur synthesis2 evidence items

Nameplate and usable capacity

One aPower 2 provides 15 kWh usable AC energy at beginning of life; up to fifteen units can provide 225 kWh per aGate under the documented design, but nameplate sums do not remove reserve, temperature, conversion or aging losses
Checked 5 days agoDirect source2 evidence items

Continuous and timed peak power

One unit is rated 10 kW continuous discharge, 15 kW for ten seconds and 25 kW for one second, with 8 kW continuous charge. Service, breaker and aGate configuration can impose a lower system limit
Checked 5 days agoDirect source2 evidence items

Coupling, inverter and controls

The battery is AC-coupled and contains its inverter. aGate supplies service isolation, metering, source control and energy management for existing or new solar, grid and supported generator paths
Checked 5 days agoDirect source2 evidence items

Transfer, islanding and loads

aGate can back the service and manage loads, but whole-home marketing is not permission to run every load simultaneously. Confirm 120/240 or 120/208 service, phase imbalance, LRA, load shedding and generator start or transfer sequence
Checked 5 days agoOur synthesis4 evidence items

Expansion boundary

Up to fifteen aPower 2 units per compatible aGate are documented, including supported pairing with named Franklin expansion products. Structural space, conductors, fault current, controls, listing, permit and utility limits must be redesigned for each expansion
Checked 5 days agoDirect source3 evidence items

Ambient and installation

The IP67 battery operates within documented charge and discharge ranges, with automatic heating in cold conditions and natural cooling. Preserve mounting, flood-depth, clearance, noise, service access, Wi-Fi and aGate environmental limits
Checked 5 days agoOur synthesis2 evidence items

Thermal, fire and stored-energy safety

LFP cells, sealed enclosure, BMS and natural cooling are safety features, not a no-fire or no-fault guarantee. The system remains high-energy electrical equipment; verify fire-code siting, emergency shutdown, flood and impact exposure and any nearby fuel or generator requirements
Checked 5 days agoOur synthesis3 evidence items

Listings, code, permit and utility

Use the listed aPower 2 plus aGate combination, applicable UL 9540 and UL 9540A records, UL 1741 and IEEE 1547 settings, local NEC, permit, utility interconnection and fire review. Generator approval is configuration-specific
Checked 5 days agoOur synthesis3 evidence items

Installer, software, cloud and privacy

The FranklinWH app and cloud receive interval energy, device, site and account data; installer and remote support roles can change settings. Confirm local operation during internet loss, access transfer, VPP or utility sharing, retention and deletion
Checked 5 days agoDirect source3 evidence items

Warranty, throughput and service

The published warranty is fifteen years or 60 MWh aggregate throughput per unit, with capacity, use, commissioning, connectivity and transfer conditions. Confirm labor, freight, aGate coverage, installer continuity and regional response
Checked 5 days agoDirect source3 evidence items

Incentives and outcome boundary

Federal section 25D does not apply to privately purchased residential equipment placed in service after December 31, 2025 under current IRS guidance. Verify state, utility, VPP, lease or business routes independently. No surge test or weather mode guarantees runtime, savings, generator autonomy or safe whole-home operation

Current verdict

The high-surge retrofit reference

aPower 2 is the defended AC-coupled route for large motor starts and generator integration when the installer can support aGate, but its higher installed benchmark must earn its place in a measured load and outage plan.

What changed

The product has a history

Older observations stay in the ledger when the current view changes. That lets a buyer tell the difference between an old complaint, an active issue, and a problem that was corrected.

    Current complete-system evidence retained

    aPower 2 was checked against current manufacturer identity, specification or manual, support and privacy, current U.S. price or documented package boundary, independent review and bounded owner or installer evidence.

Owner experience

What repeats after the purchase

Owner and installer evidence is retained as a quote, commissioning, outage-test, software and service checklist for aPower 2, not an accuracy, safety, runtime, savings or reliability rate.

Reports are self-selected and span different capacities, loads, solar, generators, services, panels, utilities, codes, climates, installers, firmware, tariffs and system ages. They cannot prove code compliance, fire safety, savings, runtime, resilience, warranty performance or whole-home outcomes for another site.
SignalWhat owners reportOur readEvidence

aGate commissioning, high-start loads, generator behavior, cloud history, firmware and installer handoff

Self-selected exact-system owners and installers discuss quotations, commissioning, outage tests, standby loss, firmware, app access, service and repair. Reports are anecdotal, configuration-specific and do not establish runtime, savings, safety, reliability or a population failure rate.

Require the installer to document the intended motor-start case, generator sequence, aGate firmware and manual local recovery, then witness both grid-loss and grid-return tests

Manufacturer identity, specification or manual, support, current U.S. price or a documented complete-system boundary, independent editorial and bounded owner or installer evidence were checked on August 19, 2026. This market covers current U.S.-supported stationary residential battery and energy-storage systems or materially different complete configurations. It excludes portable power stations, EV-only vehicle-to-home systems, bare cells and rack batteries without a supported residential system path, unsupported marketplace equipment, discontinued or orphaned systems, cosmetic bundles and capacity-module padding. Preserve exact nameplate and usable energy, continuous power, timed peak or its disclosed absence, AC or DC coupling, inverter, controller, gateway, transfer and islanding, backed-up circuits versus service, generator and solar compatibility, expansion, ambient derating, mounting, thermal management, fire and stored-energy hazards, and any coolant, refrigerant or suppression-service requirement. LFP or another chemistry, BMS protections, UL 9540 system listing, UL 9540A test evidence and UL 1973 battery listing reduce or characterize specific risks but do not make a system fire-free or guarantee AHJ approval. Retain the exact listed combination, NEC edition, permit, fire review, utility interconnection and permission to operate. Preserve installer access, app, local control, cloud, privacy, firmware, warranty, throughput, parts and service. Current IRS guidance says section 25D is unavailable for residential property placed in service after December 31, 2025; state, utility, lease, business and VPP programs are separate. No capacity, power, transfer speed, solar, generator, weather mode, tariff schedule, app forecast, quote or incentive guarantees runtime, savings, outage survival, resilience or operation of every home load.
