| The SAJ PDS33-2S2R2B-EH is a dedicated solar pump inverter/controller from the SAJ PDS33 Series, engineered to efficiently power water pumps using photovoltaic (PV) solar energy. It converts DC power generated by solar panels into three-phase AC power to drive irrigation pumps and water supply systems, making it ideal for agricultural, rural, and off-grid applications where reliable electricity may be limited or unavailable.Built with an advanced MPPT (Maximum Power Point Tracking) algorithm, the PDS33-2S2R2B-EH continuously optimises the solar array’s output to maximise energy harvest and ensure stable pump performance under changing sunlight conditions. It features robust protection functions — including overvoltage, overload, overheating, and dry-run protection — safeguarding both the inverter and the pump.Designed for flexibility, the PDS33-2S2R2B-EH supports three-phase 220 V AC output and is compatible with standard three-phase asynchronous motors, providing a cost-effective, battery-free solution for water pumping directly from solar power. Its compact, plug-and-play design simplifies installation and maintenance, while optional communication interfaces (e.g., RS-485) allow for remote monitoring and control. |
