★ Best for whole-home backup in our best home batteries

Facts checked 21 October 2026 against the manufacturer’s documents

FranklinWH sells the aPower battery with the aGate, a controller that switches the whole home to battery power in an outage. Because it’s AC-coupled, it works alongside the solar inverter you already have.

Warranty

FranklinWH’s Australian datasheet gives 12 years or 60 MWh of throughput. Some FranklinWH marketing elsewhere mentions 15 years: go by the Australian warranty document your installer gives you.

Support in Australia

The aGate X-01-AU and aPower X-02-AU are the models sold in Australia and New Zealand.

Strengths

  • Whole-home backup without changing your solar inverter
  • Large 15 kWh units, scalable to 225 kWh
  • Supports single, two and three phase homes

Watch for

  • 5 kW continuous per unit: big loads need two or more
  • Heavy, at 185 kg per aPower
  • Shorter warranty term in Australia (12 years) than some marketing suggests

Our take

If riding through blackouts is the main reason you want a battery, FranklinWH is built for it: the aGate backs up the whole home and the battery adds to any existing solar. Check one unit’s 5 kW is enough for what you run at once, or plan for two.
