The FOX ESS CQ7-V6M (w) is the master module for FOX ESS's CQ7 high-voltage residential battery system in cold-climate configuration. As the master, it contains the full system controller and BMU plus the first 6.96 kWh LFP battery module, and is required exactly once per stack. The "(w)" winter variant adds an internal heating element that lets the battery charge and discharge from -25 degrees Celsius up to +55 degrees Celsius, making it suited to Tasmania, alpine, and inland frost-prone Australian installations where standard CQ7 modules would derate. Six-LED status display, CAN-bus monitoring, IP65 rating, 100% depth of discharge.
