Overview
FranklinWH (Franklin Wireless Home) is a US-based energy storage company that has expanded into Australia with the aPower as their primary residential product. The aPower bundles serious technical capability — AC+DC coupling, V2H readiness, 5kW continuous output (10kW peak), and modular expansion — into a $7,500 package that sits in direct competition with the Sigenergy SP and Tesla Powerwall 3.
The brand is genuinely newer to the Australian market than competitors like BYD, Sungrow, or Tesla, which means installer familiarity and service infrastructure are still building. For early adopters willing to accept that trade-off, the aPower offers strong specifications.
Pricing & Installation
Indicative installed cost: $11,000–$15,000
The $7,500 aPower battery pairs with the FranklinWH aPower Hub (a separate unit managing inverter functions and coupling), adding to system cost. V2H functionality requires the aPower EV Charger module — an additional purchase.
Complete FranklinWH system pricing including hub and EV charger is competitive with Sigenergy’s equivalent V2H-ready configuration.
Performance & Output
5kW continuous / 10kW peak output from the base battery. With V2H enabled and a compatible EV, discharge capability increases significantly depending on EV battery size.
Round-trip efficiency at 95% is solid for the price point. AC+DC coupling means DC-coupled installations achieve slightly better efficiency in new builds.
Storage Capacity
13.6kWh base is generous — more than the Tesla Powerwall 3 (13.5kWh) and on par with the mid-range SBR batteries. Expandable to 54.4kWh (4 units) for large-scale installations.
Backup & Blackout Protection
Grid-forming, sub-20ms switchover, whole-home backup capability. IP55 rated for outdoor installation under an eave or in a weatherproof location.
Operating range: -20°C to 50°C — adequate for most Australian climates.
Compatibility
AC+DC coupled. The FranklinWH aPower Hub manages compatibility with multiple inverter brands. AC coupling allows retrofit to existing solar systems. DC coupling is available for new installations.
V2H compatible vehicles vary by region — check the FranklinWH website for the current Australian EV compatibility list.
Warranty & Support
10-year product warranty. FranklinWH’s Australian distributor manages warranty and service. Geographic coverage is stronger in VIC, NSW, and QLD with regional support developing.
Verdict
The FranklinWH aPower is technically sound and competitively priced for its specification level. The brand trust and installer-network gaps that come with being newer to the Australian market are the main risks. For homeowners in areas with established FranklinWH installers, it is a serious contender — particularly for V2H-focused buyers who find Sigenergy’s offering less accessible.
Best for: V2H-interested homeowners, AC+DC coupling flexibility seekers, technically-focused buyers comparing against Sigenergy SP.
