INVT CHE100 is a general-purpose frequency inverter known for its Sensorless Vector Control (SVC) V/f control
PV array voltage matching
The INVT CHE100 User Manual serves as a critical document for ensuring the longevity and efficiency of solar water pumping systems. The device is highly specialized for off-grid agricultural use. Strict adherence to the manual’s guidelines regarding , proper grounding , and motor parameter tuning is required for successful deployment. The unit offers a cost-effective, low-maintenance solution for remote water pumping applications.
Communication
: Integrated RS485 interface supporting standard Modbus protocol. Basic Configuration & Parameter Settings
Grounding:
Ensure the inverter is properly grounded to avoid electrostatic damage and reduce noise. Common Parameter Settings
Conclusion
Problem 2: The inverter trips on ERR02 (Overvoltage) when decelerating.
Manual solution:
Increase deceleration time (P0.16) or enable overvoltage stall protection (P3.08 = 1 ). For loads with high inertia, install a braking resistor (see wiring diagram in Chapter 3).
