Product Description

su10 su100 solar pump inverter MPPT 220V 380V solar pump drive pumps VFD


SU10/SU100 series solar pump inverters is a low voltage pumps inverter of0.3 to 400KW above rating designed to operate with energy drawn from solar panel or photovoltaic cells (PV).

The inverters is customized to operate in dual supply mode (Ac and DC), so the grid connected supply is used in the absence of energy from PV cells. This drive functions with the latest in technology maximum power point tracking (MPPT) algorithm to derive maximum power from the PV cells at any instant.

SU10 SU100 4kw 400KW Solar Pump Controller VFD 220V Solar Inverter 1


SU10 and su100 solar pump inverter Operation Guidance


1) Wiring:

Confirmed the solar pump inverter selecting if suitable for pump. The rated current of inverter must be bigger than rated current of pumps.

Selecting correct solar arrays for inverter. The Vmp should be 310VDC for 220VAC pump, 540Vmp for 380VAC pump.

And total power of solar arrays must be larger 1.3 times of AC pumps.

Correct connect P+ terminals to positive pole of solar panel, P- (N) to negative pole of solar panels. Otherwise it will cause inverter damage. ( It also can connect DC solar power to R and T and no need distinguish poles of panels)

Connect motor wire and ground wire to corresponding U, V, W, E terminals.


2).Parameters setting and trial run:

Set F0-01 to 0, F0-02 for 0, and F0-09, F0-11, F0-14, F0-15 parameters setting according to application site.

Set pumps parameters according to nameplate of pump in F5-00, F5-01, F5-02, F5-03, F5-04, F5-05 parameters.

Set solar pump MPPT mode FE-00 for 0002, PE05 , PE06 and PE07 parameters use to change the MPPT gain.

Press RUN button for trail running, and confirm the motor running direction.


3) Common problems and solutions

a, Q:Well-lit conditions, the pump is running, but the water is very small.

A:Check if the pump motor direction is reversed.

b, Q:Well-lit conditions, the drive is in standby mode 0.00Hz.

A:Check C-29, observe what protection status is the drive in currently, check whether the parameters set is reasonable.

c, Q:DC current is incorrectly displayed.

A:Adjust FE-33 ,FE-34 for calibration.

d, Q:Well-lit conditions,frequencysevere beating during operation.

A:PE05, PE06 and FE-07 parameters can use to adjust output frequency stability.
