Notice

To ensure safety operation of solar pump inverter, it must choose the

right way of transportation, i nstallation, operation and maintenance.

Before operations, be aware of the safety notices as below.

Danger: misuse may cause fire disaster, personal serious injury or

even death.

Warning: misuse may cause person with mild or moderate injury or

equipment damage.

Tips: prompt some useful information.

�Check

Warning

If the inverter is damaged or missing parts will not be allowed to install, otherwise

may have accidents.

�

Installation

Warning

1. In order to ensure good convection cooling effect, the inverter must be

mounted vertically , and leave at least 10cm space on the top and on the

bottom.

2. The inverter should be installed indoor with vents or scavenging

arrangement . Do not install under direct sunlight .

3. During installation, please do not fall d rilling residual fabrics into cooling fins

or fans of inverter, to prevent the impact of cooling.

�Wiring

Wiring

Danger

1. Wiring must be carried out by qualified electrical professionals , or it may cause

electric shock or fire .

2. Before w iring , make sure the input power has been cut of f, otherwise may

cause electric shock or fire .

3.

Ground terminal must be connected to the ground, or the enclosure of

the inverter may have charged danger.

4. Please choose reasonable p hotovoltaic array , electrical load and inverter,

otherwise may cause damage to device.

Warning

1. Please use the specified torque tighten the terminal , otherwise there is a fire

hazard .

2. Please do not connect capacitance and phase ahead of LC/RC noise

filter with the output of inverter. When the distance between the

inverter and the motor load more than 100 m , it is recommended to

use the output reactor.

�Operation

Operation

Danger

1. Can be energized after confirming the wiring connected correct, otherwise

may cause inverter damage or fire.

2. Do not change the wiring in the energizing, otherwise there is a risk of

electrical shock.

Warning

1. Before the first run, please adjust part of control parameters according to

instruction steps of the user manual. Please do not

change the control

parameter of inverter casually , or it may result in equipment damage.

2. During the operation, temperature of radiator is high , please do not

touch for a long time, otherwise there is a risk of scald.

3. When altitude height is over 1000m, the inverter should be used with

current derating. Each additional 1500m altitude, output current is

derated about 10% .

�Other

Other

Danger

1. Maintenance and Inspection must be carried out by quality electricalprofessionals.

2. In energized state, do not disassemble the inverter . Waiting at least 5

minutes after power failure, maintenance and inspection can be carry out, to

avoid personal injury caused by residual voltage on electrolytic capacitor

of the main circuit .

3. Absolute prohibition of self- transformation of the inverter, otherwise it

will lead to personal injury or equipment damage .

4. Processing scrap ped inverter , set the inverter as an industrial waste

processing . Internal

electrolytic capacitor may explode during burning.

Some components may produce harmful, toxic gases during burning.

Solar Pump

Pump

Pump System

System

Solar pump system consists of the photovoltaic array, solar pump inverter and AC

water pump. This system is widely used in pumping water for home use (drinking

& washing) , farm; irrigating for garden, field, desert plants; watering for livestock,

fish pond, landscaping streams and waterfalls, swimming pool, sea island, water

treatment projects, etc.

This system saves out of battery energy storage device, storage water instead of

storage power, directly drives pump for pumping water. This solar pump inverter

with high reliability, high power, while significantly reducing the system

’

s

construction and maintenance costs.

AC water pump is driven by three phase solar pump inverter. Pump ing

water from deep well, rivers or lakes to water tank/pool, or to irrigation

system and fountain systems directly. According to actual demands and

installation conditions, there are various water pumps to choose, such

as centrifugal pump, mixed-flow pump, deep-well pump.

1.2

1.2 Features

Features

Solar pump inverter controls and adjusts the working of solar pump

system, converter DC power produced by photovoltaic array to AC

power, drive water pump. According to the chang ing of sunlight intensity ,

adjust the output frequency automatically to achieve maximum power

point tracking (MPPT) .

·It applies to pumps of three phase induction motor .

·

·It adopts dynamic VI MPPT and optimized pure sine wave PWM

control, with fast response and good stability.

·Fully a utomatic operation, it can set the range of water pump rotational

speed according to the actual conditions .

·

The main power circuit adopts digital power mod ule s, with high

reliability and high efficiency 98%.

·

·It has the complete electric protective functions. Protected against

overload, over voltage, under voltage, over heat, reverse polarity,

thunder, over flow and dry running.
