S afety In stru cti on

To ensure safety operation of solar pumping inve rter, it mus t c hoose the right way of transportation,installation,opera tion and maintenan ce. Before opera tions, be aware of the safety notices as below:

Warn ing: Misuse willresult in f ire, s erious injury to pers on or even death.

Caution: misuse will cause low or middle-grad e injury to person or equipmen t damage.

Prom pt: P oi nt out s ome usefulinformation.

Purc hase Inspection

CautionI f the inverter is dam ag ed or m issi ng part s, it willnot be allowed to i ns tall, ot herw is e m ay hav e ac cidents.

Installation

Caution

1. To ensure good convection cooling effect, the inverter must be installed vert ical ly.

2. Install it in the indoo r condition which is possessed of ven tilation opening or ven tilating device. It is

forbidden to install where exp oses directly to the sunlight.

3. Do not let the drilling remai ns fall into the inve rter cooling fins or fans during installation in c ase the

dissipation is effected.

Connection

Caution

1. Each wire connected to the inve rter must be wrapped with electrical tape for safety.2 . Con nection jo b must be carried out by qualified electricalprof es sionals, or else it willcaus e electrocution

or fire.3 . Please confirm t hat input pow er has already been cut off, or else it willcause electr ic shock or fire.4 . Eart h terminalmus t be reliab ly ground, or else the inve rter shell willhave a dan g er of being electrified.5 . The type selection of PV array, motor load and inverter must be reasonable , or else the equipment will be

damag e d.


2

Running

Caution

1. Please us e the fasten terminalof the specified torque, or else it will cause fire.2. Do not connect the output term inalof the inverter to the capacit or and phase -advanced LC/RC noise filter.

It is recommend touse the output reactor when the distance betwee n the inve rter andthemotor load

more than exceed s 100 m.

Caution

1. Adjust partial control parameters according to the steps indicated by the manual before its first runn ing.

Do not change the control param e ters of the inve rter randomly, or else it will cause dam age to the

equipment.

2. Because the heat sink's t em perature is high during running, do not touc h it f or a long time, or else it will

cause burn.

3. In the condition of altitude over 1000m, the inve rt er should be dera ted f or use, that is, out put curren t will

be de-ra ted by 10% at every 1500 m increment of height.

Warning

1. Maintenan ce and inspection must be performed by the qualified electric professionals.

2. Do not dismantle the inverter during electrifying. Con duct maintenance and inspection at least 5 minutes

after the power off.

3. It is absolutely forbidden to recons truct the inve rter by oneself, or el se it will cause personnel injury or

equipment damage.

4. Treat the inverter as industrial waste when pro cessing the abandoned inverter. It is possible that the

electrolytic capacitor will explode during incineration and that part of componen ts will pr oduce toxic and

harmful gas.

Chapter 1 Sys t em Introduction

1.1 Introduction of Solar P um ping System

Solar pump ing system becomes more and more popular, it can be appli ed to dai ly use (underground water),

agriculture irri gation, forestry irrigation, desert control, pasture animal husban dry, water supply for islands,

wastewater treatment engineering, and so on. In recent yea rs, with thepromotion of theutilization of new

ener gy resources, solar pumpi ng systems are more an d more us ed in municipal engineering, city center

square s, parks, tourist sites, resorts and hotels, the landscapes and fountain systems intheresidential

area s.

This system is composed of solar array, 3 phase AC pum p and s olar pumping inverter. B ased on the design

philosophy that it is better to store water than elec tricity, there is no energ y storing device such as s tore

battery in the system.

Structure of solar pumping system

The s olar arra y,an aggre gation of many s olar modules c onnected in series and parallel, absorb s sunlight

radi ation and converts it into electrical energy, providing dyn amical wat er for the whole sys tem. The

pumping inver ter controls and adjus ts the system operation and converts the DC produced by s olar array

into AC to drive the pump, and adjust the output frequen cy in real-time according to the variation of sunlight

intensity to realize the maximum pow er point tracking (MPPT). The pump, drive by 3-pha se AC motor, can

draw wat er f rom the deep well s or river s and lakes to pour i nt o the st orage tank or reserv oi r, or di rect ly

c onnect to the irrigation sys tem, fountain sys tem, et c. According to the ac tual syst em demand and

installation conditions, different types of pump such as centri fugal pump, axial flowpump, mixed-flow pump

or deep-we llpump can be used.

2.5 S ensor ( Opti onal)

Our solar pumping inverter has sensor interf ac e and along with s ensor contactor with short lead ne twork

cabl e. Then you can use anti-interface network cable to prolong this line. This network cable is a sensor for

tank full and well dry. I t has 9 core wires: 4 wires used as tank sensor; 4 wires used as well sensor. 1wire

connected with ground. Sensor cable as below:

How does sensor work?

A) 4 wires us ed as well sensor. Bl ue, red, w hite-blue and w hite-red. Each wire ’s terminal should be

removed the cover, leave core outside. Blue used as high sensor. Red us ed as middle sensor. White-blue

and white-red together us ed as lowest sensor.


10

Remar k: You can set the sensor place as you like.

B) 4 wires us ed as well sensor. Green, bro wn, white-green and white-brow n. Each wire ’s terminal

should be removed the cover, leave core outside. When c ore touch the wat er, it is s ensor. Green used as

high sens or. B rown used as middle sensor. White-green and white-brown together used as lowest sensor.

Remark: The sensor part is optional according to your applicatio n. But if you want to use t hesensor function, it must set as below: (this part is in sensor setting)

If wa ter level reaches the lowest sensor,

means water is very little, inve rter starts to

drive pump to pump wat er.

If water level reaches middle sensor, means

tank water is muc h. Inver ter continues to drive

pump topump water.

If water level reaches high sens or, means tank

is full . Inverter wi lldri ve pump to s top pum pi ng

water.

This middle sensor should be fixed a bit far above pump ’s

water incom ing hole. If water level meets this middle

sens or, means well water is littl e, inve rter should stop to

drive pum p, otherwise pump will damage without wat er.

This lowest sens or should be under pump ’s water

incoming hole. Y ou can make it long or short as you like.

T hi s hi gh s ens or shoul d be fixed abov e m iddl e sens or, you

can fix it at any place as you like, but it s hould be under

water. When water cover s three sensors, inverter starts to

drive pump to pump wat er.


11

1. Tank sensor

When it just used Tank sensor, Tank s ensor should be Yes, and well sensor be No.

2. Well sensor

Only Well sensor, Tank sensor sets No and well sensor beYes.

3. Tanksensor & Well sensor

When Tank sensor & Well s ensor are used, both set Yes.Instead, when sensor function is no need, please set both are NO ,otherwiseitcannotwork.
