Fox ESS BMS Box for CQ16
Fox ESS CQ16 base and BMS box — Four modules and a BMS Box at the bottom, forty-five and three at the top — H3 Plus only.
The CQ16 is the largest modular storage Fox ESS make, developed specifically for the H3 Plus series, and it scales further than anything else in their range.
About the Fox ESS CQ16 base and BMS box
The floor is four modules with one BMS Box, at 64.28 kWh. The ceiling is forty-five modules with three BMS Boxes, at 723.15 kWh. Between those, the constraint is fifteen modules in series per stack.
Both parts on this page are structural rather than optional. The base is what the stack stands on; the BMS Box is what manages the modules and talks to the inverter.
It is an indoor product: IP20, floor mounted, with intelligent air cooling control and a 90 % depth of discharge.
The compatibility line is absolute. CQ16 works with the H3 Plus series only and is not compatible with other Fox series.
