To achieve a 48kWh storage capacity with Fox ESS, you typically need to move beyond a single stack and use a parallel configuration or the newer, high-density CQ or EP series.

Standard Fox ESS modular stacks (like the ECS or EQ series) generally max out around 30–42kWh per tower, so a 48kWh system usually consists of two parallel stacks.

Technical Data: 48kWh System (Parallel ECS/EQ Setup)

This setup typically uses two separate towers connected to a single high-power 3-phase inverter (like the Fox H3 series).

• Total Capacity: ~48.36 kWh (using 12 modules total).

• Usable Capacity: ~43.52 kWh (at 90% Depth of Discharge).

• Configuration: 2x Stacks (Each with 1 Master BMS + 5 Slave modules).

• Battery Type: LiFePO4 (Lithium Iron Phosphate).

• Nominal Voltage: Determined by the stack height (typically ~345V per stack).

• Max Charge/Discharge: Up to 100A (when paralleled, depending on inverter limits).

• IP Rating: IP65 (Indoor/Outdoor).

• Communication: CAN / RS485.
