The CQ7 is a high-performance, scalable battery storage system. The modular design allows for maximum flexibility, making it suitable for a broad range of storage applications.
Additional batteries can be installed in series, allowing for a maximum storage capacity of 98.28kWh. Installation is easy, with a plug and play solution that can save valuable time for installers.
The CQ7-US-M is the dedicated Master Module (BMS/Controller unit) for the US version of their modular high-voltage energy storage system. In a typical stack, this master control module sits directly on top of the sub-modules (slave batteries) to control communication, safety parameters, and power routing to your solar inverter. It pairs with a CQ7-US-S Sub module to form scalable battery stacks—each CQ7-US adds ~7.02 kWh of capacity.
