A complete 4kWh home battery system
This VoltX PowerFlex 3000 kit pairs the Power Module with 1 battery module for 4kWh (4025.6Wh) of LiFePO4 storage in one package. Store free or off-peak electricity and use it during higher-rate hours or an outage, with a simple plug-in AC connection. It suits homeowners, renters, time-of-use customers and small businesses managing everyday energy and backup for selected loads.
Cut peak costs and back up outages
Charge when electricity is cheapest, then use stored energy when it costs more.
- Store free or off-peak power and discharge during higher-rate periods
- Up to 2000W output for compatible household and small-business loads
- Set a Backup SOC in the app so a reserve stays ready for the next outage
4kWh of LiFePO4 capacity
More stored energy for longer runtime.
- 4025.6Wh across the Power Module and 1 battery module
- Supports compatible fridges, freezers, routers, NBN equipment, CCTV, security systems and lighting
- LiFePO4 cells rated for up to 8000 cycles
Expand further, any time
Room to grow as your needs change.
- Add 4 more Battery Modules to reach 12kWh
- Tool-free stacking beneath the existing modules, no rewiring
- Capacity adds runtime; output stays at the 3000W maximum
Plan your installation space
Confirm the area can safely fit the complete stacked system, with room for ventilation and at least 30mm clearance behind the heatsink. Follow the user manual when stacking or securing modules, and switch off the system and disconnect AC input before adding or removing a module. Check the running and starting power of any appliance before use.
