FranklinWH Debuts Upgraded 15 kWh Home Battery Across Australia and New Zealand

FranklinWH has officially launched its enhanced 15 kWh aPower battery for residential customers in Australia and New Zealand. The upgraded system promises higher energy density and improved integration with solar arrays.

According to the company, the new aPower delivers 15 kWh of usable capacity with a continuous power output of 5 kW, peak of 8.5 kW. The battery uses lithium iron phosphate chemistry, targeting homes seeking greater energy independence.

“Homeowners are demanding longer backup durations and smarter energy management,” said Derek Baird, FranklinWH’s Vice President of Global Sales. “Our enhanced aPower meets that need with a compact footprint and advanced software controls.”

The launch marks FranklinWH’s continued expansion in the Asia-Pacific region, where battery storage adoption is surging amid rising electricity prices and grid instability.

Background

FranklinWH originally introduced the aPower line in 2022, offering modular storage up to 30 kWh. The latest 15 kWh variant improves on earlier models by boosting round-trip efficiency to 96% and extending cycle life to 6,000 cycles.

Australia remains one of the world’s fastest-growing markets for residential batteries, with over 3 million solar households. New Zealand has also seen a 40% year-over-year increase in battery installations as demand for resilient energy systems climbs.

“Battery storage is no longer a luxury—it’s a necessity for households looking to insulate themselves from price spikes and blackouts,” noted Dr. Emily Tran, an energy analyst at the Clean Energy Council.

What This Means

For Australian and New Zealand homeowners, the enhanced aPower offers more usable storage per square foot than many competing units. Its compatibility with FranklinWH’s aGate controller enables whole-home backup during outages.

The system also supports time-of-use optimization, automatically charging during low-rate periods and discharging when peak rates apply. This can reduce electricity bills by up to 30% for typical households.

Industry experts see the launch as a signal that the residential battery market is maturing, with companies focusing on reliability and integration rather than just capacity. “This isn’t just a bigger battery; it’s a smarter one,” added Baird.

The enhanced aPower is available now through FranklinWH’s network of certified installers in both countries. Pricing starts at approximately AUD $12,000 before installation.

Global Context

FranklinWH faces competition from Tesla Powerwall, Sungrow, and Sonnen, but its emphasis on high cycle life and modularity sets it apart. The company plans further feature updates via over-the-air firmware.

“This is a clear step toward making home batteries as standard as solar panels,” said Tran. “FranklinWH is betting on Australia and New Zealand leading that transition.”

With the enhanced aPower, the company aims to reinforce its position as a key player in the region’s energy storage landscape. Installation slots are already filling up for the coming months.
