Basic principle

Si200 solar pumping system can provide water for remote areas lacking of electricity or places where the electricity supply is unstable. PV pump controller can convert the DC power from solar panels to AC power so to drive various kinds of pumps.System enables continiously pumping when in good weather. System is not equipped with strorage battery devices, it is suggested that pumping the water to conservation pool
for future use.Water source could come from river, lake,well,or other natural water source or special soucre.System enables application of floating switch in the conservation pool or water tower to control the operation of pumps. Low water level probes can be installed in the well to detect the water level of the well in order to stop the pumps when the well in low water level. Diagram 1 is a typical SI200 PV pumping
system. The main parts and compenents of this system is after diagram 1.



SI200 PV pumping system is composed of following parts:
A Solar panels ,
B , DC circuit braker or disconnector
C , SI200 PV pump controller
D , Pump
E , well water level switch(optional)
F , water tower water level switch(optional)
SI200 PV pump controller can start the pump softly and is consistent with the electricity
coming from the changes providing by solar panels. The advantage of soft starting is
avoid surge or power surges when the pump or motor are in the process of starting,whi-
ch reduce the loss of motor and pumping system.

  Note:
 





In order to ensure continuous supply water, user can manual switch the SI200 PV pumping system to the standby AC power supply when the light is insufficient or rainy weather. When switching, DC and AC power interlock need to be ensured. Alternate AC  power not only can be local network but also can be diesel generator (Please refer to 2.4.3 input and output parameter table).

Note:
At any moment, there is only one kind of power can be input, otherwise, it may lead to controller failure.

Three phase 380 VAC Alternate AC power supply, for example, wiring diagram such as following:



If pump motor voltage is three phase 220-240VAC, the single phase 20VAC alternate power supply L/N wire need to connect to the controller main terminal R/T.
