6.4.1 Single phase pump description
Single phase pump is widely used in household and small power water delivery system
with its advantages of simple structure, low cost, low noise, easy access to power, etc.
Usually, single phase pump consists of a main winding (running winding), a secondary
winding (starting winding), and a starting capacitor.
Note: Some single phase pump consists of two capacitors, one starting capacitor and
one running capacitor. In the connection of single phase pump, this two capacitors are
always connected together, after that, the connection is same as one capacitor pump.

While using our JNPxL-V5 series single phase solar pump inverter, the capacitor of
single phase pump needs to be removed. Then draw a wire at the common end of the
main and secondary windings, draw two wires at the other end of the main and
secondary windings. Then connect this three wires and one ground wire to the AC
connector of inverter, as shown below:
