The CQ7 is a high-performance, scalable battery storage system designed for flexible energy storage. Its modular design allows additional batteries to be installed in series, increasing storage capacity as system requirements grow.
With 7.02kWh capacity per module and scalability up to 98.28kWh* in a single stack (multiple stacks can be connected to certain inverter models), the CQ7 gives installers a practical way to build storage around the needs of each project – from smaller systems to larger-capacity installations. Installation is designed to be simple, with a plug-and-play solution that can help save valuable time on site.
The CQ7 is designed as a scalable high-voltage battery system, with additional batteries installed in series to increase storage capacity.
The CQ7 offers 7.02kWh capacity per module, allowing storage to be scaled to suit different system requirements.
With support for up to 7 modules (1-phase) and 14 modules (3-phase) the CQ7 can scale to a maximum storage capacity of 98.28kWh per input.
The CQ7’s modular design allows for maximum flexibility, making it suitable for a broad range of storage applications. Installation is designed to be simple, with a plug-and-play solution that can help save valuable time for installers.
Minimum Stack: 3 Modules
Maximum Stack: 12 Modules†
No. of Stacks: 1
Maximum Capacity: 84.24kWh
Each stack will consist of 1 x master (CQM) and additional slave (CQS) battery modules.
†An optional base is available to enable larger stacks to be split into two columns (front to back).
