Wiring description:
It is accepted dual power AC/DC mode connecting input.
User can able to install a power switchover to selection which mode power input as conditions.
Wiring P+ and P- of DC solar power to R, T terminals, or 1/3 phase cables of AC power supply to R, T ( R, S, T) of inverter. Connect 1 phase 220VAC AC input L, N to R and T terminals of inverter.
Built a Run/Stop switch S1 to start pumping when setting P0.02 for 1,that inverter works in terminals control mode. This inverter can achieve auto start at morning when sun light radiation is good, auto stop when sunset when sunlight radiation is low.
Built a switch 2 to disable solar pump control mode when connecting AC grid input. The inverter can be used for a variable speed drive (VFD) for pumps speed adjusting as need The output frequency can be adjusted by P0-03 frequency reference mode setting. The MPPT function is closed when turn off switch 2 and set P4.02=53. The solar pump control mode function also can be disable by parameters setting PE00=0
.
Connect 2 wires of float ball sensor to DI4 and COM for water tank level fulling detecting, and set P4.03=51( float ball NO relay alarm). When water level reached to sensor detecting, the normal open (NO) relay point will be activated, inveretr stop pumping, and sent a A.FuL alarm.
Connect 2 wires of sensor of dry run sensor of well to DI5 and GND, and set F4.04=52 ( dry run NC relay alarm). It will sent alarm A.LLd and stop pumping when lack of water in well for dry run protection.
