The RPS 400V Solar Well Pump Kit is an efficient, high-volume off-grid water system designed for use in remote locations. This centrifugal pump is ideal for sandy or sedimentary water sources, providing reliable water pumping with a low head and high volume capacity. Perfect for keeping large stock tanks or ponds full during the summer months, the RPS 400V uses fewer solar panels but delivers the same high-performance pump as the RPS 800V model. The RPS 400V kit provides an impressive up to 16 GPM at low heads, making it an excellent solution for filling large stock tanks, ponds, and other water reservoirs. The centrifugal pump impellers are highly resistant to wear, ensuring long-term durability, even in tough water conditions. This off-grid system includes all the necessary components to get started, such as 4x 100-watt solar panels, an RPS centrifugal pump with a DC brushless motor, and an efficiency-boosting pump controller for smooth start/stop operation. It also comes with essential accessories like hose barbs, low-water well level sensor, tank shut-off sensor, and heat shrink wire splice kit for easy installation. Additionally, the kit contains 20ft of solar wire, a ground lug, and a manual to ensure a complete setup.
