2．Brief introduction of equipment.

The HSPL/HXXXXL/HA/B series products are convert the DC output of the PV array to AC and

drives the pump, according to the PV array output power (caused by sunshine intensity

change) regulates output frequency to achieve the maximum power point tracking.

Solar pumping system is composed by Solar array, the equipment, and pump ,it is

mainly used for agricultural irrigation, desertification control, grassland animal

husbandry, city water, living water and other fields; with low carbon, energy saving, play an

active role in improve the water shortage area people's living standard and the ecological

environment.

2.2 CHARACTERISTICS

1. Applies to the use of three‐phase asynchronous motor pump;

2. MPPT, maximum power point tracking algorithm for dynamic VI, fast response speed, good

stability, the efficiency of MPPT 99%;

3. Fully automatic operation, can according to the actual situation to set free the speed range

of pumps

4. Using efficient SVPWM algorithm, the main circuit and high reliability, the

highest conversion efficiency up to 98% ;

5. Intelligent recognition of input voltage range, without the need to manually adjust the open

circuit voltage, maximum power point voltage

6. No button set to run automatically, only a switch control stop and boot;

7. The maximum flow support manually controlled, prevent stop and boot repeatedly when

water less or less needs of water

8. The function of protecting the motor complete, can choose the upper and lower water level

monitoring and control circuit, to prevent dry or over flow‘s pumping;

9. IP52~IP64, use environment temperature: ‐20 ℃ ~ +50 ℃;

10. Allows a wide range of input voltage, L type 250‐450Vdc, H type of 460‐750V

11. Over‐voltage, over‐current, over temperature , short‐circuit ,against lighting protection

12. DC Input anti‐reverse function

13. Small size and lower weight

Table 1

Remarks.

①The selection of pump: the pump can't: low head instead of the high head pump, high lift

pump is not the same place of low lift pump.

②: "lift range” and "flow range”: flow and head is inversely proportional, higher lift means low

flow.

3.2 DC Input

a. Please refer to the Table‐1 and check the input voltage whether within the standard or not...

Then input voltage can be measured by multi meter. For example:220V AC output ,so the DC

input voltage range is: 250V~450V

b. If you needs can connect the switcher

c. Please make sure the input negative and positive line wiring correcting

3.3 AC Output

Picture ‐ 2

AC output wiring method please refer to the Picture‐2, length of wire is 0.5M, include the

3‐phase and ground wire. The red color wire is for 3phase AC output，Yellow‐Green wire is for

Ground wiring. Please make sure correctly wiring and grounded, forbid to connect the switcher

between the device and pump.

3.4 WELL and TANK SENSOR

Picture ‐ 3

Length wire of well and tank is 0.5M, each sensor have three wire, include High level of water

detect, middle level of water detect, low level of water detect. For example of Well Connecting

Method（Tank connect wire is the same）：

1) The longest length of reserved wire is for well low level of water detect

2) The middle length of reserved wire is for well middle level of water detect

3) The shortest length of reserved wire is for well high level of water detect

Remarks: The connection is not on basis of line color difference, according to the length of

reserved line
