Buy quality 5HP Solar Pump Inverter VFD from leading China manufcaturer CSIVEI. It is engineered for medium-sized solar irrigation systems. Featuring dual MPPT inputs, it handles varying solar conditions and supports both single and three-phase pump motors. Advanced sleep/wake mode extends pump life by stopping at low solar power and restarting when sufficient power returns. The drive includes a built-in data logger for daily water output and energy monitoring. Communication options (RS485 Modbus) allow remote control via SCADA or IoT devices. With an optional IP54 enclosure for outdoor use, this CSIVEI VFD is perfect for rural water supply, livestock farms, and crop irrigation.

This solar VFD is perfectly suited for livestock watering (cattle, sheep, horses) in pastures far from power lines, as well as aquaculture (fish ponds, shrimp farms). It drives submersible pumps from wells to fill troughs, or circulates water in ponds to maintain oxygen levels. Features like low‑voltage start and automatic restart after cloud passage ensure continuous operation. In fish farming, the drive can be paired with aerators or circulation pumps to prevent stagnation. Benefits include zero fuel cost, low maintenance, and silent operation. Common uses: remote cattle ranches, pig farm water supply, tilapia pond aeration, and shrimp farm water exchange.
For applications requiring 24/7 water availability, the CSIVEI 5HP Solar Pump Inverter VFD supports multiple power source configurations:
● Pure solar mode – runs entirely on solar panels; ideal for daytime irrigation and livestock.
● Solar priority with grid backup – uses solar as primary; automatically switches to grid when solar insufficient or pump demand exceeds solar capacity.
● Solar priority with generator backup – same logic for diesel/gas generator, perfect for remote sites without grid.
● Solar + battery storage – charges batteries from surplus solar; runs pump from batteries at night or cloudy periods.
● Grid / generator only mode – for maintenance or emergency.
The built-in energy management controller seamlessly transitions between sources without interrupting pump operation. A communication port allows remote monitoring of energy flow and water output via SCADA or IoT.
Q1: How much water will my pump deliver per day with this solar drive?
A: Water output depends on solar irradiation, panel size, pump efficiency, and head. A rule of thumb: for every 1kW of solar panels, a typical pump delivers 3‑5 m³/day per 10m head. Use CSIVEI’s online solar pumping calculator with your site data for accurate estimates.
Q2: Can I control the pump from my smartphone?
A: Yes, with the optional CSIVEI Smart Pump App (iOS/Android) and a cloud gateway. You can start/stop the pump, adjust speed, view real‑time solar power and water flow, and receive alarm notifications.
Q3: What is the maximum DC input voltage?
A: The maximum DC input voltage for this drive is 800V and 1000V for higher power units. Please refer to the specification sheet for exact values. Always ensure your solar array open-circuit voltage stays within the drive’s rating.
Q4: How do I connect the dry‑run protection sensor?
A: The drive has dedicated digital input terminals for a flow switch, pressure switch, or water level electrode. Connect the sensor’s NO/NC contacts; then set the corresponding parameter to “dry‑run protection”. The drive will stop and display a fault when the sensor triggers.
Q5: Why does the drive show “Low DC Voltage” fault even when panels are in sun?
A: Possible causes: panel wiring too thin/long causing voltage drop, too many panels in parallel (increase series for higher voltage), shading on panels, or faulty panel connections. Check DC voltage at drive terminals; it should be above the drive’s minimum start voltage.
