Hybrid Solar Pump Inverter FAQ
1. What is a solar water pump inverter, and how does it work?
A solar water pump inverter converts DC power from solar panels into AC power to drive submersible water pumps. It supports MPPT (Maximum Power Point Tracking) for maximum power extraction, achieving over 99% efficiency. The device can drive various AC pumps, including both single-phase and three-phase types. It also drives permanent magnet synchronous motors (PMSM). The inverter supports three power supply modes: pure solar, grid AC, or hybrid.
2. What precautions should you take when installing an inverter?
Install the inverter in a well-ventilated, cool, dry, and waterproof location. It should have an IP54 or higher protection rating. Avoid direct sunlight and high-temperature environments. Use a level to ensure vertical mounting during installation. Leave adequate space around the unit for heat dissipation. Ensure all cable connections are secure and use waterproof connectors. Install separate circuit breakers for both DC and AC sides.
3. How does hybrid mode work, and how do you set the optimal switching frequency?
In hybrid mode, solar power takes priority. When the solar output frequency exceeds the set value (such as 25Hz), the system uses only solar power. If the frequency remains below this threshold for more than 20 seconds, grid AC power automatically supplements it. Determine the optimal frequency through actual head testing. Gradually increase the frequency from low to high. Find the minimum frequency that can just deliver water to the destination (such as 35Hz). Use this value as the optimal hybrid/stop setpoint.
