About sunswitch in Solar water pumping
What is the exact meaning of sunswitch? I have a project in which the owner told us to use sunswitch to reduce the pressure in pump. We are using kirloskar pump of capacity 15 KW and a controller. Can this pump controller featured with sunswitch property or we have to install it separately. If so then can how we install it and suggestion of any brand of sunswitch is highly appreciated.
