Aquatec SWP submersible pumps are designed to supply water in off-grid locations for homes, irrigation, livestock, ponds, and many other applications. The SWP-4000 4" positive-displacement submersible deep well diaphragm pumps are constructed with high-grade materials that are all potable water safe. The SWP pumps are designed to operate from any 12-30 VDC power source, including 60 cell modules or 72 cell modules or arrays (using the paired Aquatec 30V 250W Solar Pump Controller to limit the voltage input to the pump to 30Vdc maximum), or 12VDC or 24VDC battery banks.
The Aquatec APC-30-250 is designed specifically to be an interface between a photovoltaic array, and the Aquatec SWP series submersible pumps. It is a solid-state power converter that optimizes and protects the solar well pump. The controller automatically extends pump run time by the use of current boosting, and provides protection from excessive Voltage and Current, as well as dry-running.
