Installation and wiring of PV series solar pump inverter.

The inverter accept both power supply source of DC solar power and AC grid input, but only allow one power supply input at the same time when no connecting protection diode before P+ an P-.
In generally, suggest user to connect a AC/DC manual switchover (S) to select if solar DC power input or AC grid input by manual.
Note:Forbidden connect DC power supply to P+ and PB of PV350, otherwise it will cause serious damage.
Wring steps
1. Recommend that connecting solar DC power supply to R, T terminals, ( also can connect P+ and P-, but please pay great attention of polarity connecting, positive to P+, negative to P-).
2. Connect a S1 switch to start inverter for pumping when set for terminals command control mode, and set P0.01=1, P5.00=1.
3. Connect S2 switch between X3 and COM when connect Ac grid power supply, when S2 is turn on, it will disable the solar pump control function, make inverter runs as a general purpose VFD, and set P5.02=51.
4. Connect float ball switch between X4 and COM for water tank fulling detecting, and set P5.03=54. when water is fulling ,NO switch of sensor will be turn on to stop pumping. Inverter will start again once the water level lower again.
5.Connect a float ball sensor normal close (NC) switch between X5 and COM in the well for dry run protecting. Ans set P5.04=55. If there are shortage of water in well, it will stop inverter pumping.

Operation  steps:
1. Selecting correct inverter models according to the rated voltage, rated current of AC pumps.
Selecting to 2T series for 220VAC pump, the rated current of inverter should be bigger than pump’s.
Selecting 4T series for 380VAC pumps;the rated current of inverter should be bigger than pump’s.
Selecting 5T series for 480VAC pumps( Maximum DC voltage is 900VDC).
2. Check solar arrays input DC voltage and total input power if correct, check Voc open circuit voltage of solar arrays, and total input power of arrays.

Input voltage, power solar arrays selection
Pumps model	Inverter models	Vmp	Voc	Total Power of solar arrays
110VAC pumps	1S	110*1.41=130VDC	156VDC	≧ (1.3 to 2.0) rated power of pumps It is also depend on the quality of solar panels. The more power input, the better performance.
220VAC pumps	2T	220*1.41=310VDC	372VDC
380VAC pumps	4T (Max 800VDC)	380*1.41=540VDC	648VDC
480VAC pumps	4T ( Max 900VDC)	480*1.41=677VDC	812VDC

265w, 38Voc (Open circuit voltage), 31Vmp ( Voltage at Pmax)
Inverter models	Power of pump	Connection in series (PCS) (Vmp)	Connect in parallel ( Strings) Power	Total (PCS)
1T (110VAC)	0.75kw to 1.0kw	5 PCS	1* strings	5*1=5
2T (220VAC)	0.75kw to 1.5kw	10PCS	1* strings	10*1=10
2T (220VAC)	2.2kw	11PCS	1* strings	11*1=11
4T(380VAC)	0.75kw to 2.2kw	18PCS	1* strings	18*1=18
4T(380VAC)	3.7kw	19PCS	1* strings	19*1=19
4T(380VAC)	5.5kw	18PCS	2* strings	18*2=36
4T(380VAC)	7.5kw	19pcs	2* strings	19*2=38
4T(380VAC)	11kw	18pcs	3* strings	18*3=54
4T(380VAC)	15kw	19pcs	4* strings	19*4=76

* For selecting 5T models for 480VAC pumps, the Vmp should be 480*1.41=677VDC, and around 811Voc.
3. Wiring as above inverter connection diagram, connect DC solar power supply to R, and T ( P+, and P-), connect pumps input cables to U, V, W of inverter , start switch s1, water fulling float ball switch s2, well dry run function sensor switch S3.
4. Set H9.02 value with actual Vmp of on site solar arrays for quick jump into MPPT calculating.
5. Confirm the inverter if work in solar pump MPPT control mode in H9.00=0.
6. Set motor group parameters for pump protection from P2.00 to P2.03. If the selecting inverter power as same as rated current of motor. It is no need to set this group parameters.
7. Check the water delivery, water outcome if good or not, check the pumps running direction is correct or not, if the running direction is not correct, please change any 2 phase order of U, V. W wiring.
8. Set auxiliary protection function, such as pumps lowest running speed, dry run protection, maximum current of pumps, minimum input power of solar arrays, PQ curve setting for accuracy flow and today flow indicating in HF group.
9.If need, connect water tank fulling sensor. There are two types water level sensor, digital and analog 0-20mA, connect as diagram showed.
10. If system request to run automatically, inverter start at early morning when sunlight is sufficient automatically, and stop at sunset when no enough radiation automatically, please connect a start switch S1 between X1 and COM, set P0.01=1 ( terminals control), and keep this switch in normal close status.
Note: H9 and HF both group parameters is special designed for solar pump control purpose only.
When H9.00=0, solar pump control will be disable, the output frequency is not depend on sunlight. 
For the MPPT gain function is defined by H9.06, H9.07, H9.08 and H9.09. If set these parameters are bigger, the MPPt calculating is stronger.
