C ProX Series Inverters 1.5 kW to 8 kW

The C ProX Series is a flexible MPPT inverter platform for standalone residential, agricultural, and light-commercial systems. Four power levels cover compact 12 V battery installations through to higher-capacity 48 V systems. Pure sine-wave output, grid and generator input support, BMS communication, and integrated Wi-Fi provide a controlled foundation for modern off-grid power systems.

The 1.5K and 4.2K models start their MPPT range at 30 V DC, supporting lower-voltage PV arrangements. The 6.2K and 8K models operate from 90 V DC, with battery-independent operation requiring at least 100 V DC on the 6.2K according to the official technical sheet. Maximum PV capacity ranges from 2000 W on the 1.5K to 10000 W across two PV inputs on the 8K.

The 4.2K, 6.2K, and 8K models provide dual AC outputs. This allows priority loads and optional loads to be separated so that essential equipment can be managed independently when battery state or available generation is limited. Charging-current capability of up to 120 A supports appropriately engineered battery banks and higher daily energy throughput.

Model selection must consider more than nominal wattage. Battery voltage, PV input current, number of PV inputs, battery-only output capability, motor-starting demand, and required separation between essential and non-essential loads all influence the correct configuration.

Engineering and Selection Notes

• Use the battery-only output figure, not only rated power, when the system must support loads during periods without PV contribution.
• Dual-output models allow priority-load design, but the load allocation and control logic must be defined during system engineering.
• Verify PV operating voltage, cold-weather open-circuit voltage, and per-input current against the selected model.
• The 8K model provides two PV input paths and must be stringed according to the stated 22 A x 2 current limit and 5000 W x 2 power allocation.
• Confirm battery BMS protocol compatibility, charging-current limits, cable sizing, protection, and battery capacity before commissioning.
