| Product introduction | ||||
| RS−P Solar Water Pump Controller can accept PV input, single phase 220V and three-phase 380V inputs. It uses clean solar energy that is environment friendly and unlimited. It can also be powered by emergent diesel engine or grid power, and have variable frequency and energy saving features. | ||||
| System components | ||||
| The system mainly has 3 parts: power supply, controller and load. The power supply is PV (Photovoltaic) array, generator or grid. The controller is mainly the RS−P Solar Water Pump Controller. The loadis 3-phase asynchronous motor or pump. The system does not need battery for storing energy, which not only cuts the cost, but also protects the environment. RS−P PV Pump Controller can directly drive various kinds of 3-phase asynchronous motor, with high power integration and less components, which improves the system reliability. | ||||
| Operating principles | ||||
| RS−P series controller converts DC into adjustable 3-phase AC and can track the maximum power change of PV panel array. The maximum peak power tracking (MPPT) technology ensures the input power to be at the peak power all the time. The tracking range is adjustable, which flexibly utilizes the PV characteristics of solar cells. The vector control technology can perform auto learning to 3-phase asynchronous motor, which increases the efficiency of the controller to 93% to 99%, and fully uses the solar energy. The controller can be powered by solar energy, single phase 220V or 3-phase 380V grid power. In addition, the control terminalprovides rich extension functions to realize flexible system application scope. | ||||
