For the purpose of this manual and the product the following symbols are used.

Overview:

The system operates on power generated using solar PV (photovoltaic) system. The photovoltaic array converts the solar energy into electricity, which is used for running the motor pump set. The pumping system draws water from the open well, bore well, stream, pond, canal etc. The system requires a shadow-free area for installation of the Solar Panel. Of all the ways solar electricity benefits the people on Earth, none makes as much difference in the daily lives as pumping water. By providing water for irrigation or potable water have obvious benefits for people in rural areas and especially for those in developing nations. The proper choice is determined by application specific factors like how much water is required and whether the water should be available at night or just during high sun hours.

Solar Power and Irrigation:

 Irrigation is best utilisation of Solar power  Usually area which require more water have high solar irradiation  During summer time when more water is require, there is more sun light  Water need not be available at night  Maintenance facilities are lacking, Solar pump run maintenance free.  Solar tracking can use.

 Electrical Wiring

You will connect wiring to the input of the inverter. First, you must determine whether the inverter model you have required three-phase power only, or single-phase power only. All models have the same power connection terminals [R/L1], [S/L2], and [T/L3]. So you must refer to the specifications label (on the side of the inverter) for the acceptable power source types! For inverters that can accept single-phase power and are connected that way, terminal [S/L2] will remain unconnected. Note the use of ring lug connectors for a secure connection.

Operating Principle 5

And Hardware

 Operating Principal and Hardware:

 Solar Water Pump Inverter :

 WJ200 & SJ700 Series of Hitachi Inverter is low voltage range AC drive and it

available for 0.4Kw to 400Kw Motor rating which is design for drawing maximum power from PV module (Photovoltaic Cell).

 Inverter has design to operate in Dual power supply AC power and DC power.

 It is operating Maximum power point tracking algorithm to derive maximum power

from PV cell at any instant while in cloudy or sunny weather.

 This inverter series specifically design for pump application which has special

reduce torque control mode with energy saving technology.

 It is design for meet requirement of pump manufacturer and OEM to customize

application as per their requirements.

 Control Mode: Reduce Torque technology is mostly utilized in pump application

where load on motor shaft have very high inertia / momentum. It operates on starting torque is normal and afterword torque is going to reduce and increase speed of motor. So, less power require to achieve higher speed of motor. It operate Energy saving function while reaching nearly constant speed where optimizing input power by reduce of output voltage and current.

 MPPT overview

 The Hitachi solar inverter uses maximum power pint tracking control software to

operate solar panel (PV) at maximum power generation level.

 Hitachi solar inverter internal MPPT algorithm is used to derive maximum power

form PV cell at any instant and it is happen by changing output voltage and current in PV cell until maximum power is obtained.

 When inverter is in stop command then PV cell generating short circuit current and if

the PV cells are not connected to any load, then output voltage of cell is same as open circuit voltage of PV.

 See below I-V characteristic

 The I-V curve is not constant for all instant, the intensity of sun ray and temperature

changes during a day time. The current changes linearly with Intensity and voltage change very small with temperature changes. So, for constant temperature, Maximum power varies proportionally with intensity of sun rays. The Maximum power is obtain at knee point of I-V curve.

Error Code

Name

Cause(s)

E01

Over-current event while at constant speed

The inverter output was short-circuited, or the motor shaft is locked or has a heavy load. These conditions cause excessive current for the inverter, so the inverter output is turned OFF. The dual-voltage motor is wired incorrectly.

E02

Over-current event during deceleration

E03

Over-current event during acceleration

E04

Over-current event during other conditions

E05

Overload protection

When a motor overload is detected by the electronic thermal function, the inverter trips and turns OFF its output.

E06

Braking resistor overload protection

When the BRD operation rate exceeds the setting of "b090", this protective function shuts off the inverter output and displays the error code.

E07

Over-voltage protection

When the DC bus voltage exceeds a threshold, due to regenerative energy from the motor.

E08

EEPROM error

When the built-in EEPROM memory has problems due to noise or excessive temperature, the inverter trips and turns OFF its output to the motor.

E09

Under-voltage error

A decrease of internal DC bus voltage below a threshold results in a control circuit fault. This condition can also generate excessive motor heat or cause low torque. The inverter trips and turns OFF its output.

E10

Current detection error

If an error occurs in the internal current detection system, the inverter will shut off its output and display the error code.

E11

CPU error

A malfunction in the built-in CPU has occurred, so the inverter trips and turns OFF its output to the motor.

E12

External trip

A signal on an intelligent input terminal configured as EXT has occurred. The inverter trips and turns OFF the output to the motor.

E13

USP

When the Unattended Start Protection (USP) is enabled, an error occurred when power is applied while a Run signal is present. The inverter trips and does not go into Run Mode until the error is cleared.

E14

Ground fault

The inverter is protected by the detection of ground faults between the inverter output and the

motor upon during powerup tests. This feature protects the inverter, and does not protect humans.

E15

Input over-voltage

The inverter tests for input over-voltage after the inverter has been in Stop Mode for 100 seconds. If an over-voltage condition exists, the inverter enters a fault state. After the fault is cleared, the inverter can enter Run Mode again.

E21

Inverter thermal trip

When the inverter internal temperature is above the threshold, the thermal sensor in the inverter module detects the excessive temperature of the power devices and trips, turning the inverter output OFF.

E22

CPU communication error

When communication between two CPU fails, inverter trips and displays the error code.

E25

Main circuit error (*3)

The inverter will trip if the power supply establishment is not recognized because of a malfunction due to noise or damage to the main circuit element.

E30

Driver error

An internal inverter error has occurred at the safety protection circuit between the CPU and main driver unit. Excessive electrical noise may be the cause. The inverter has turned OFF the IGBT module output.

E35

Thermistor

When a thermistor is connected to terminals [5] and [L] and the inverter has sensed the temperature is too high, the inverter trips and turns OFF the output.

E36

Braking error

When "01" has been specified for the Brake Control Enable (b120), the inverter will trip if it cannot receive the braking confirmation signal within the Brake Wait Time for Confirmation (b124) after the output of the brake release signal.

E37

Safe Stop

Safe stop signal is given.

E38

Low-speed overload protection

If overload occurs during the motor operation at a very low speed, the inverter will detect the overload and shut off the inverter output.

E40

Operator connection

When the connection between inverter and operator keypad failed, inverter trips and displays the error code.

E41

Modbus communication error

When ―trip‖ is selected (C076=00) as a

behavior in case of communication error, inverter trips when timeout happens.

E43

EzSQ invalid instruction

The program stored in inverter memory has been destroyed, or the PRG terminal was turned on without a program downloaded to the inverter.

E44

 Common Fault and Remedies

 Fault: During running pump Find E09.x – Under Voltage Alarm

Remedies: First to check x value, Suppose E09.2, E09.3 and E09.4 means during deceleration, Constant speed and acceleration condition Then Check following parameters F002 – 50second F003 – 10 second A017 – 02 MPPT enable D004 – DC voltage of PV input power

 Fault: If find E07.x – Over Voltage Alarm

Remedies: First to check PV module Open circuit Voltage (Voc) value and no of PV connected in series connection. If Total Voc value is higher than 800VDC then Inverter will show over voltage alarm. then try to reduce PV qty in series. Now, Best selection as below for series and parallel connection Example: If, Pump motor voltage is 415VAC, Then try to make Total Vmp value of connected near to 585 to 600VDC. It should be 1.414 time of Pump motor voltage

 Fault: If find E01, E02, E03, E04 and E05 during starting of pump

Remedies: Check following parameters F002 – 50 second (Up to 90kw inverter) B021 – 03 overload restriction enable A044 – 01 Pump control mode Try to change B049 – 01 VT mode, B022 – max value and B023 – 0.1sec

 Fault: If find E14 – Ground fault

Remedies: Check motor wires and its earth cable. Inverter has two screw terminal One cable for incoming and other for motor earth cable If Earthing cable is properly connected then check inverter to pump motor distance, if it more than 100meter, please try to use output line reactor (output choke) with minimum 3% impedance. If there is no any motor cable and only DC power input, then asked to service person from company.
