This kind of solar AC pump controller is used in the solar panel array power supply environment and grid power supply frequency conversion control mode, and can drive all Three phase AC pumps. (need to change internal parameters when using power supply frequency conversion control mode)
The controller can automatically control the operation and shut down of the electric pump according to the output voltage of the solar panel array and water level signals without manual protection.
That is to say, run when the sunshine is strong, stop when the sunshine is too weak, run when the well is full and the tower is dry, stop when the well is dry and the tower is fulI. In order to get the best performance and maximize the efficiency of solar energy, the controller automatically slows down the pump when the sunshine is weak and output voltage of solar panel is not enough, to avoid causing the controller to stop too soon and the working time of the whole system is too short.
·Operation: It can be set to start automatically after power-on or one-button start/stop, and it is easy to use the power supply mode without setting too many parameters.
·Display: The controller uses the digital tube + LED indicator display mode, the digital tube is for displaying the digital content, and the LED indicator is for displaying the unit, such as: When the digital tube displays 50.00, the LED indicator will light up in the Hz position.
Display content: basic parameter setting display, controller preset parameter display when stop, controller output and input parameter display when running; The fault code display when running.
Protection function: over current, over voltage, under voltage, phase loss, overload, module overheating, low frequency, dry turn, low power, well dry, tower full.
·Compatible sensors: liquid level probe, float, electric contact pressure gauge, pressure switch, pressure sensor.
·Model: MS220VD (0.75-2.2KW), MS220VT 3.7-45KW), MS380VT (0.75-75Kw).
·DC voltage level: the highest voltage 400VDC(MS220VD and MS220VT series), the highest voltage 800VDC(MS380VT series).
·MPPT voltage range: 260-375VDC(MS220VD and MS220VT series), 486-750VDC(MS380VT series).
