FAQ

Review our frequently asked questions to understand exactly how the SD600 series integrates into your specific project requirements and solves common agricultural challenges.

Q1: How does the dual supply mode handle the transition between solar and AC grid power?

The inverter features a seamless switching mechanism. When the MPPT algorithm detects that the DC voltage from the solar array has dropped below the minimum operational threshold, it automatically draws the required supplementary power from the connected AC grid or diesel generator, ensuring zero interruption in water flow.

Q2: Can this inverter be used with existing standard AC submersible pumps?

Yes, absolutely. The SD600 series is designed to output standard 3-phase or single-phase alternating current, making it fully compatible with traditional AC submersible deep well pumps. This eliminates the need to purchase specialized, expensive DC pumps for your project.

Q3: What is the recommended sizing ratio between the solar panel array and the inverter?

For optimal performance and to ensure the pump operates at full capacity during peak daylight hours, we highly recommend that the total input power from the solar array be at least 1.2 times the rated capacity of the water pump.

Q4: How does the dry-run protection feature operate without manual supervision?

The inverter utilizes low water probe sensors installed directly in the well or reservoir. If the water level drops below the sensor, the smart software instantly registers the change in load and halts the motor. The system remains in a protective sleep mode until safe water levels are restored.

Q5: Is it possible to monitor multiple inverter units across different agricultural sites simultaneously?

Yes. By equipping the inverters with our optional GPRS modules, project managers can connect multiple units to our dedicated mobile APP. This allows for centralized, real-time monitoring of performance metrics, PQ curves, and fault alerts across various geographical locations from a single device.
