370W Built-in Controller Solar DC Screw Deep Well Pump Stainless Steel For Storage Battery Car Accumulator Electric Bike, High Efficiency

Compact, stainless-steel 370W solar DC screw deep-well pump with built-in controller — a brushless series designed for agriculture, deep well water supply, household use and similar field applications. The unit runs directly from PV panels, starting and stopping automatically, and offers a compact footprint, modern styling and easy operation and maintenance. When planning daily operation: if you assume a power generation efficiency of 50%, the pump can be specified for about 6 hours per day or 8 hours per day. For correctly sizing the solar array, first determine the pump input power. Then account for PV output by dividing that input power by a panel generation efficiency of 65% (up to 70%), or multiply the pump input by 1.5 — the result is the nominal solar panel power required to reliably drive the pump.You may also like 4.5L Portable ULV Cold Fogging Machine, 1400W – 8-10 meters (adjustable) Spray, 5 meters Cord — For Home/Office/School Bus.
