Description
Product Description & Working Principle
The SWP High-Power Solar Pump Inverter operates by converting DC power from photovoltaic arrays into variable-frequency AC power to drive high-capacity water pumps.
Using intelligent frequency control, the inverter automatically adjusts pump speed according to available solar energy, ensuring smooth startup, reduced mechanical stress, and stable water output.
When integrated with grid or generator input, the system can operate in hybrid mode, maintaining uninterrupted pumping during low solar conditions while prioritizing solar energy whenever available.
Typical Applications
- Large-scale agricultural irrigation systems
- Deep-well and high-lift water pumping
- Municipal and rural water supply projects
- Water transfer for reservoirs and canals
- Mining, oilfield, and industrial water supply
- Desert, plateau, and remote off-grid regions
Q1: Can these inverters operate continuously at full load?
A: Yes. The SWP160KH-V1 to SWP450KH-V1 series is designed for long-term continuous operation under heavy load conditions.
Q2: Are these models compatible with hybrid grid or generator input?
A: Yes. They support flexible hybrid configurations for uninterrupted water supply
Q3: How does the inverter protect pumps from dry running?
A: Built-in dry-run protection detects abnormal load conditions and automatically stops the pump to prevent damage.
Q4: What types of pumps are supported?
A: The series supports three-phase submersible pumps, centrifugal pumps, and multi-stage high-head pumps.
