What is the CQ7 Battery System?
Direct Answer: The Fox ESS CQ7 is a high-voltage lithium battery storage system designed to store solar energy efficiently and supply power when needed, reducing reliance on the grid.
Unlike traditional fixed systems, the CQ7 uses a modular architecture, allowing you to scale your energy storage as your needs grow — making it ideal for:
- Residential homes
- Commercial energy systems
- Solar + battery hybrid setups
Why CQ7 Stands Out
- Modular Expansion = Smarter Investment
Start small and expand anytime. 1 module: 7.02kWh, up to 14 modules in series, max system: 98.28kWh. Most competitors force upfront overspending. CQ7 lets you scale with your budget.
- High Voltage = Better Efficiency
Operating voltage up to 919.8V with lower energy loss vs low-voltage systems. Translation: More usable power, less waste.
- High Usable Energy (90% DOD)
Use 90% of stored energy. Many systems only allow 80–85%. That’s up to 10% more usable energy daily.
- Built for Australian Conditions
Charge: 0°C to 55°C, Discharge: -10°C to 55°C. Outdoor-ready (IP65).
- Safety + Longevity
LFP battery (Lithium Iron Phosphate), fire protection system included.
