With rising electricity costs in Sydney and across New South Wales, more homeowners are turning to battery storage to increase solar savings and reduce dependence on the grid. One battery gaining strong attention is the FoxESS CQ6 battery.
The FoxESS CQ6 Battery is designed for Australian homes seeking safe, scalable, and cost-effective energy storage. For homeowners comparing options against Tesla Powerwall or BYD batteries, the CQ6 offers a practical alternative with modular expansion and advanced Lithium Iron Phosphate (LFP) safety.
At Solar World Power, we help homeowners assess, supply and install FoxESS battery systems designed to maximise solar self-consumption and long-term savings.
The FoxESS CQ6 is a modular solar battery designed to store excess solar energy generated during the day for use at night, during peak electricity periods, or during outages when backup is configured.
The CQ6 works with compatible FoxESS hybrid inverter systems and can suit both new solar installations and some battery retrofit projects.

The FoxESS CQ6 uses Lithium Iron Phosphate (LFP) chemistry known for:
Start with one battery module and expand later if you:
This staged approach can reduce upfront costs.
Lithium Iron Phosphate (LFP)
6kWh per module
6000+ cycles
Up to 90–95%
Over 95%
Use more of your own solar instead of importing expensive grid power.
A battery can improve solar self-consumption and increase the value of your solar investment.
Configured systems may help keep essential circuits powered during outages.
Compared with premium-priced systems, FoxESS can offer strong value per kWh.
