Safety Instructions

WARNING: This chapter contains important safety and operating instructions. Read and keep this manual for future reference.
Inspection
If missing components or a 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 that the voltage range of the PV panel meets the requirement.
2. Check if all wires are firmly connected without a short circuit. Otherwise, it will cause equipment damage.
3. Do NOT install this inverter under direct sunlight because high temperatures 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 a metal non-combustible surface.

1. CAUTION!! Only qualified personnel can install and operate this inverter.
2. To reduce the risk of electric shock, disconnect the power source before making a wire connection. Otherwise, it may cause electrical shock.
3. To reduce risk of electric shock, NEVER touch any terminals on electric circuits.
4. If the connection cable between the inverter and water pump is more than 50m, please be sure to install a three-phase AC reactor. The inductance value for each phase is about 1mH. Otherwise, the water pump would be easy to be damaged.

Operation

1. Only after the wire connection is complete and put the cover back to the inverter, it entered to do commissioning. Otherwise, it will cause electric shock
2. If sunlight is sufficient but little water is pumped, maybe the wires on the motor connection are reversely connected. Please reverse any two wires of them.
3. When testing the water pump, be sure to install the water pump at the appropriate water level. Never allow the 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 the power source within 5 minutes. Only service after the bus voltage is within safe range.

Warning: The places of input sockets of DC positive pole and negative pole of different models are different.
Warning: The signal marshaling sequence of AC output sockets of different models are different.

Assemble DC Connector

Strip the cable 6-8mm,then connect the bare wire core into core tube of the 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 the slot of connection until hearing the sound indicating fit in place.

Tighten the nuts to finish the wiring.

Warning: Risk of electric shock! Before shifting the solar panel, disconnect the pump inverter AC and DC. Besides, allow 5-minute internal capacitance discharging.

Assemble AC Output Connector
Connection to the AC output side terminal for Growatt SPI 750-5500TL series solar pump inverter, there are two types of AC connector mode.
For type I of 3 phase AC output connector: AC connector 1,2,L, PE gets connection with the pump through 4 wires (U wire, V wire, W wire, and PE wire)
For type II of 1 phase AC output connector: AC connector L, 1, PE gets connection with the pump through 3 wires (L wire, N wire, and PE wire)

Remove the parts of the AC connection plug from the accessory bag. Guide the pressure screw sealing right, threaded sleeve over the AC cable. Insert the stripped and bared conductors U, V, W, PE into screw terminals with signs U, V, W, PE on the socket element and tighten the screws.

Push the threaded sleeve into the socket element. Screw the pressure screw tightly onto the threaded sleeve.

Insert the AC connection plug into the AC connection receptacle on the inverter.

Assemble AC Input Connector

Remove the parts of teh AC connection plug from the accessory bag. Guide the pressure screw sealing right, threaded sleeve over the AC cable.

Insert the stripped and bared conductors L, N, PE into screw terminals with sign L, N, PE on the socket element and tighten the screws.

Push the threaded sleeve into the socket element. Screw the pressure and screw thightly onto the threaded sleeve.

Insert the AC connection plug into the AC connection receptacle on the inverter.

Wiring of Water Level Sensor

Connection to the COM terminal for Growatt SPI 750-5500TL series solar pump inverter, the water tank connects water level sensor 2, and the water well connects to water level sensor 1.

Notice: connect water level sensor 1 and detect water shortage. Respectively connect two signal lines of the sensor with 3 and 4 of COM terminal. When water level sensor 1 detects that the water level of the well is lower than the level set by the sensor, the pump inverter will delay for 5s, then turn off the output protection pump. The water level recovers. Wait for 20s, then the pump inverter re-works normally.
Notice: connect water level sensor 2 to detect whether water is full. Connect two signal lines of the sensor with 1 and 2 of COM terminal. When water level sensor 2 detects that the water level of water tank exceeds the level set by the sensor, the pump inverter delays for 5s and turns off the output; when the water level is lower than set level, wait for 20s, then the pump inverter re-starts to work normally.
