Control module – FoxESS – CQ16-BOX
Product details
CQ16
The CQ16 from FOX ESS is a high-voltage energy storage system designed for indoor floor mounting. Its modular design allows the system’s nominal energy capacity to be scaled from 64.28 to 241.05 kWh. The system offers a 90% depth of discharge and intelligent air cooling.
Key advantages of CQ16
- Scalability: from 4 to 15 modules connected in series, each with a nominal capacity of 16.07 kWh.
- Depth of discharge 90%: enables the use of a significant portion of the stored energy.
- Round-trip efficiency above 92%.
- Lifespan of 6000 cycles at 0.5C and 90% depth of discharge, down to 70% battery state of health (SOH).
- Intelligent air cooling and CAN communication.
- Indoor floor mounting and an IP20 protection rating.
Who is this a good choice for?
CQ16 is an option for users who need an energy storage system with a capacity of 64.28–241.05 kWh, with the number of modules adjustable to the required capacity. It is suitable for users with space for indoor floor-mounted installation. Each battery system requires one CQ BOX device.
