Solar Water Pumping, Matched to Your Well
Solar-powered submersible pumps with brushless motors and MPPT controllers for agricultural irrigation, livestock watering and household water supply. Choose the model by water demand, total head and well diameter.
The DC range includes 2SS/3SS, 2SC, 3SC, 4SC, 3SSC, 4SSC and 4/6SSC families. A matched controller adjusts motor speed to available sunlight. Select a pump from its head–flow curve at the required duty point, then size the PV array and water-storage capacity for the site.
MPPT Control
Tracks available solar power and adjusts pump speed as sunlight changes.
Automatic Protection
Controller protections cover abnormal voltage, overcurrent, phase faults, short circuits, water shortage and high temperature.
Practical Water Supply
Options for deep wells, farm irrigation, livestock and household water storage.
System integration
From Sunlight to Reliable Water Supply
Match the pump, controller and PV array to the hydraulic requirements of the site.

Product FAQ
Your questions, answered.
Pump selection, solar sizing and daily water supply.
How do I select the right DC solar pump?+
Start with daily water demand and required flow, then calculate total dynamic head from the lowest operating water level to the tank, including pipe and fitting losses. Check well diameter and match the duty point to a pump curve.
Are maximum flow and maximum head achieved together?+
No. They are separate limits on the pump curve. The delivered flow decreases as head increases. Use the curve to check the required flow at the actual total head.
Does every model use 48V?+
No. DC voltage is model-specific. The selected DC families include 24V, 48V, 72V, 110V and higher-voltage variants up to 280V. Always match pump, controller and PV array.
How many solar panels are needed?+
The catalog recommends PV power of at least 1.3 times pump power. The model table gives reference quantities using 580W modules. Final series/parallel wiring must also satisfy controller voltage and current limits and site temperature conditions.
Can it pump continuously at night?+
A solar-only configuration depends on available sunlight. A water tank can store daytime production for later use. Any electrical storage or alternative supply must be designed for the selected controller; it is not assumed to be included.
Does this page cover AC/DC pump models?+
This page focuses on the DC deep well families. The download extracts the DC section from the supplied catalog; A/D dual-supply models are outside this page.
