摘要： Device for controlling solar driven water pumps with three selectable modes on the control panel being: I) speed mode with 100% use of the available solar DC power at all times; II) solar mode using available solar DC power only, and III) eco mode combining the use of the available solar DC power with the use of the AC power from a grid or a generator and/or batteries, by automatic switching between two stages, being (i) solar stage running on solar DC power only, and (ii) hybrid stage running with solar DC power and AC power from grid or generator and/or batteries like in speed mode. The purpose of the present disclosure is to preferentially use solar energy from solar panels over AC current from the electric grid or from a generator and/or batteries while ensuring sufficient pumping capacity.
