Description
Fox ESS DQ6.6 – Battery module
The FoxESS DQ6.6 is a high-performance, modular high-voltage battery storage system based on long-life LiFePO₄ technology, designed for a wide range of storage applications in both residential and commercial settings. The minimum configuration, comprising 1 master and 2 slave modules, offers a usable capacity starting at 19.86 kWh and can be expanded in stages up to 92.68 kWh simply by adding further modules. Thanks to plug-and-play installation, an integrated pre-heating function for winter operation and natural convection cooling, the DQ6.6 is equally suitable for indoor and outdoor use – fanless, silent and low-maintenance. CAN communication ensures seamless integration with compatible FoxESS inverters.
