VoltX PowerFlex 3000 AC Off-Peak Home Battery, Expandable 2kWh to 12kWh, 1000W-3000W LiFePO4 Energy Storage.

Store free or off-peak power, use it when it matters

The VoltX PowerFlex 3000 is a smart 2016Wh plug-in home battery that stores free or off-peak electricity and powers selected loads when energy costs more. It suits apartments, renters, homeowners, time-of-use customers and small businesses that want a simpler way to manage everyday energy. During an outage, stored energy can support compatible essentials such as fridges, freezers, routers, security systems and lighting.

Who it is for

• Apartments, renters and homeowners who cannot install or do not want a whole-home battery, using a standard AC connection
• Time-of-use customers with free, off-peak or lower-rate periods, charging cheap and using it later
• Fixed essential loads: garage freezers, second fridges, routers, NBN equipment, CCTV and lighting that may also need backup
• Small-business selected loads: display fridges, POS systems, routers and CCTV where tariff management and limited backup help daily operations

Cut peak costs and keep a reserve

Charge when electricity is cheapest and use stored energy during higher-rate hours. Set a Backup SOC in the app so a reserve stays ready for the next outage, and monitor charge, discharge and status from your phone.

Expandable capacity and output

Start with the 2kWh Power Module, then add compatible Battery Modules as your storage or backup needs grow. One Power Module supports up to five Battery Modules, expanding the system to about 12kWh. Output increases to 3000W with two battery modules; further modules mainly add stored energy and runtime.

• Power Module only: 1000W, 2kWh
• Power Module + 1 Battery Module: 2000W, 4kWh
• Power Module + 2 Battery Modules: 3000W, 6kWh
• Power Module + 3 Battery Modules: 3000W, 8kWh
• Power Module + 4 Battery Modules: 3000W, 10kWh
• Power Module + 5 Battery Modules: 3000W, 12kWh

Battery Modules are sold separately.

Plan your installation space

Before adding battery modules, confirm the area can safely fit the complete stacked system, with room for ventilation and heat dissipation, including at least 30mm clearance behind the heatsink. Follow the user manual when stacking, securing or removing modules, and always switch off the system and disconnect AC input before installing or removing a module.

Built to last

LiFePO4 chemistry rated for up to 8000 cycles, intelligent BMS protection and a 10-year Australian warranty, with local after-sales support through the original AU purchase channel.
