AC/DC hybrid motor could offer two option and back up power for user, one hybrid pump= 1 BLDC PUMP+ 1 AC PUMP. Using encapsulate motor (water filled motor), no risk of leakage than oil motor Using thrust bearing, lower parts loss The thrust and motor bearing effectively higher, life longer    Solar Pump Model    6SP17-2 Flow max   650L/min Head max 40m DC voltages range 60-380Vmp  (60-440VOC) AC voltages range 90-240VAC Connection in series PV 300W*10 Pump diameter 6” Outlet size 3” Max input power    3KW
