Vehicle-Powered Backup Power with Extended Runtime
Same fast charging. Twice the usable energy.
The DriveCharge™ Home Backup – Plus system builds on the Core setup by adding a Smart Extra Battery, giving you more runtime and more margin without changing how the system charges or operates.
This is the most popular option for households wanting reliable overnight backup power without stepping into larger, more expensive systems.
Charging behaviour is identical to the Core system — you simply store more energy.
| System | Capacity | Best for | What it can cover | Not ideal for |
|---|---|---|---|---|
| Home Backup – Core | ~2 kWh | Evening essentials | Wi-Fi, lights, devices, TV, short fridge runtime | All-night heavy loads |
| Home Backup – Plus | ~4 kWh | Overnight + more headroom | Essentials + longer fridge runtime + better outage resilience | Heating / cooking appliances |
| Home Backup – Extended | ~6 kWh | Multi-day essential backup* | Essentials for longer outages with careful load management | High-draw whole-home running |
*Runtime depends on what you power, how you manage loads, and how much you drive/charge.
No — charging speed is the same. The benefit of the extra battery is longer runtime because you’re storing more energy.
Yes. You can expand capacity with additional compatible batteries if your backup needs grow over time.
It can. If you commute/drive regularly, you can shift some evening usage off peak-time grid power by using the stored energy at home.
