This pump will deliver up to 1000 gallons (3785 litres) per day from shallow wells and will pump as high as 230 feet (70 meters). It comes complete with a water tight quick disconnect electrical connection that does not require splicing. Housed entirely in plastic and is able to run dry without damage. It can be run PV direct or from batteries. Field replaceable parts. Optional pump controller for use on PV direct applications.
Controller acts as a kind of a "transmission" between the solar panels and the pump, matching the output of the panels to what is required by the pump. These type controllers are usually called "LCB's", or linear current boosters. An LCB is a DC to DC converter, and is a form of maximum power point tracking (MPPT). LCB's essentially trade voltage for current, providing more current, especially at lower light levels, to the pump. LCB's will typically give you about 25-30% more water pumping per ...
