Safety Instructions
WARNING: This chapter contains important safety and operating instructions.
Read and keep this manual for future reference.
Inspection
If missing components or damaged inverter is found after receiving, please do NOT install or operate it.
Otherwise, it may cause human injury or equipment damage.
Installation
1. Before installation, please make sure if the voltage range of PV panel meets the requirement.
2. Check if all wires are firmly connected without short circuit. Otherwise, it will cause equipment damage.
3. Do NOT install this inverter under direct sunlight because high temperature may cause equipment damage.
4. Please install the inverter away from inflammable and explosive objectives. Please ensure no liquid can
enter the inverter.
5. Please install the inverter on metal non-combustible surface.

2
1. CAUTION!! Only qualified personnel can install and operate this inverter.
2. To reduce risk of electric shock, disconnect power source before making wire connection. Otherwise, it may
cause electrical shock.
3. To reduce risk of electric shock, NEVER touch any terminals on electric circuits.
4. If connection cable between inverter and water pump is more than 50m, please be sure to install a
three-phase AC reactor. Inductance value for each phase is about 1mH. Otherwise, water pump would be
easily to be damaged.
Operation
1. Only after wire connection is complete and put cover back to the inverter, it’s Enter to do
commissioning. Otherwise, it will cause electric shock
2. If sunlight is sufficient but little water is pumped, maybe the wires on motor connection are reversely
connected. Please reverse any two wires of them.
3. When testing water pump, be sure to install water pump at appropriate water level. Never allow water
pump in dry running. Otherwise, the inverter will activate protection.
Maintenance
1. Only qualified personnel can maintain, repair, inspect the inverter and replace any components.
2. It may still contain energy after disconnecting power source within 5 minutes. Only service after the bus
voltage is within safe range.

Pump
Introduction
Solar Pumping System
This is a solar pump inverter which allows power to be switched from the DC power obtained from solar panels to the
AC power needed to control the pump.
This series solar pump inverters are built-in with MPPT solar charger to maximize solar power. The inverter is suitable
for submersible pumps, ground pumps, swimming pool pumps and other pumps using three phase asynchronous
motors.
Features
Rated power 3KW to 22KW
Inbuilt MPPT solar controller
IP65 protection level
Built-in full protection and self-diagnosis
Soft start function
Comprehensive LCD and LEDs display real-time system status

INSTALLATION
Unpacking and Inspection
Before installation, please inspect the unit. Be sure that nothing inside the package is damaged. You should
have received the following items inside of package:
 The unit x 1
 User manual x 1
Mounting the Unit
Consider the following points before selecting where to install:
 Do not mount the inverter on flammable construction
materials.
 Mount on a solid metal surface.
 Avoid direct sunlight. Be sure the environment is shady and
cool.
 Be sure to install the inverter into a box with waterproof and
dustproof.
 Install this inverter at eye level in order to allow the LCD
display to be read at all times.
 The recommended installation position is to be adhered to
the wall vertically.
 Be sure to keep other objects and surfaces as shown in the
diagram to guarantee sufficient heat dissipation and to
have enough space for removing wires.

Assemble DC Connector
Strip the cable 6-8mm,then connect the bare wire core into core tube of connector.
Crimp contact barrel by using a hex crimping die. Put the contact barrel with striped cable in the corresponding
crimping notch and crimp the contact. Insert the core tube into slot of connection until hear the sound
indicating fit in place.
Tighten the nuts to finish the wiring.
Warning: Risk of electric shock! Before shifting solar panel, disconnect the pump inverter AC and DC. Besides,
allow 5-minute internal capacitance discharging.
Assemble AC Connector
AC connnector gets connection with the pump through 4 wires (U wire, V wire, W wire and PE wire)
Remove the parts of teh AC connection plug from the accessory bag. Guide the pressure screw sealing right, threaded
sleeve over the AC cable.

Assemble Sensor connector
Insert the stripped and bared conductors 2,4 in to screw termianls signal 2,4 on the socket element and tighten the
screws.
Push the threaded sleeve in to the socket element. Screw the pressue screw thightly onto the threaded sleeve.
Notice: connect water level sensor 1 and detect water shortage. Respectively connect two signal lines of sensor
with S4 and COM of I/O circuit board. When water level sensor 1 detects that the water level of well is lower than the
level set by sensor, the pump inverter will delay for 60s, then turn off output protection pump. The water level recovers.
Wait for 600s, then the pump inverter re-works normally.
Notice: connect water level sensor 2 to defect whether water is full. Connect two signal lines of sensor with S2
and COM. When water level sensor 2 detects that the water level of water tank exceeds the level set by sensor, the
pump inverter delays for 60s and turns off output; when water level is lower than set level, wait for 120s, then pump
inverter re-starts to work normally.

c. Water output test of pump
Click the run button to observe the running frequency and wateroutput.Under the normal strong light
condition,if the working frequency is low or the water volume is small,it indicates that the motor line may be
connected reversely,so it is necessary to set function code P00.13=1 or exchange the wiring of two motor
lines.
d. After finishing parameter setting of water pump, set P00.01=1. The operation code channel is altered as
original automatic mode instruction.
Notice: If the inverter fails,set P00.18 to restore the factory settings.
