What determines your CQ7 quote?
The battery stack is only one part of the system. We price the CQ7 modules, controller, compatible hybrid inverter, installation, switchboard work, cable run, commissioning and any backup hardware, then apply eligible rebates at point of sale.
| Quote factor | Why it matters |
|---|---|
| Stack size | Each CQ7 module adds 6.96 kWh usable capacity. |
| Inverter | Sets charge/discharge power and whether single- or three-phase backup is possible. |
| Three-phase supply | A compatible three-phase inverter is needed for balanced loads and broader backup. |
| Backup design | Essential circuits, EPS hardware and switchboard changes add scope but keep critical loads live. |
| Site conditions | Cable distance, wall or floor mounting and access can change labour and compliance work. |
Three-phase and blackout backup
A three-phase CQ7 design suits homes with ducted air-conditioning, pool pumps, large solar arrays or an 11 kW EV charger. For backup, your installer must define whether the system protects essential circuits on one phase or supports broader three-phase loads. The CQ7 battery does not provide blackout protection without the correct inverter, EPS setup and switchboard configuration.
