The invention discloses a control system of a solar water pump. The control system of the solar water pump saves energy consumption. According to the technical scheme of the invention, the control system of the solar water pump comprises a photovoltaic cell panel, a water pump, a two-way independent MPPT photovoltaic tracking module, an energy storage module and an inverter module. The output endof the photovoltaic cell panel is connected with the input end of the two-way independent MPPT photovoltaic tracking module and the input end of the energy storage module. The output end of the energystorage module is connected with the input end of the two-way independent MPPT photovoltaic tracking module. The output end of the two-way independent MPPT photovoltaic tracking module is connected with the input end of the inverter module. The output end of the inverter module is connected with a motor of the water pump, and the inverter module is a pulse width modulation inverter. The control system is applied to the technical field of water pump control.
