Application of Odeli frequency converter in the photovoltaic water pump industry
The traditional photovoltaic water pump drive control system has the following shortcomings
1. Unable to dynamically adjust the output speed based on sunlight, lowering the voltage of the photovoltaic panel, resulting in excessive current in the photovoltaic water pump drive control system, which can easily cause malfunctions
2. The application control of photovoltaic water pumps is not perfect, such as weak light sleep, high water level sleep, under load warning and other control and protection functions.
3. The switching control between photovoltaic power supply and urban power grid is complex. At night, if there is no PV input energy, the water pump will stop working. Some projects require the water pump to remain in working condition at all times;
4. Remote control is not supported, making it impossible for mobile applications or websites to monitor the running status of the machine and control the system to start or stop working.
Odeli photovoltaic water pump frequency converter
Based on the high-performance vector core control algorithm without speed sensors, the Odeli frequency converter combined with the application control characteristics of photovoltaic water pumps has developed an expert intelligent control algorithm to achieve maximum power point tracking (when the sunlight is sufficient, the water pump operates at full rated capacity; when the sunlight is weakened, the operating frequency is reduced; when the sunlight is further weakened, the shutdown is exited). And some special functions for photovoltaic water pumps have been added, such as control and protection functions such as weak light sleep, strong light wake up, high water level sleep, and under load warning. The dual circuit safety design of photovoltaic power supply and urban power grid conversion can achieve automatic switching function without manual intervention, ensuring the normal operation of the water pump. Supporting GPRS module, people can operate the system through website platforms or mobile applications.
For water pumps with a power of less than 2.2KW, when we configure solar panels, the photovoltaic power is sufficient, but the photovoltaic output voltage is insufficient. Therefore, we need to purchase more solar panels to increase the photovoltaic voltage. But the Odeli frequency converter can provide a boost module, supporting low PV voltage input and high DC voltage output to reduce the number of photovoltaic panels used. The automatic switching module can detect the output voltage of the voltmeter and send the voltage signal to the frequency converter. The frequency converter will control the contactor to open or close the AC input. large
