damage to the equipment, and advise on how to avoid the danger. The following warning
symbols are used in this manual:

        Electricity warning warns of hazards from electricity which can cause physical
        injury and/or damage to the equipment.

        General warning warns about conditions, other than those caused by electricity,
        which can result in physical injury and/or damage to the equipment.
8 Safety

Safety in installation and maintenance
These warnings are intended for all who work on the inverter, motor cable or motor.

 Electrical safety

        WARNING! Ignoring the following instructions can cause physical injury or death,
        or damage to the equipment.
Only qualified electricians are allowed to install and maintain the inverter!
• Never work on the photovoltaic generator or inverter and its input/output cables when
   the inverter is connected to the power system or to the photovoltaic generator.
•   Before working inside the inverter cabinet, switch off or isolate the auxiliary voltage
    supply to the inverter.
•   Isolate the inverter from the photovoltaic generator using the safety switch of the
    generator or by using the isolation switch.
•   Do not touch the input of the isolation switch that has high DC voltage.
•   After disconnecting the inverter from the power system or the DC input supply, wait for
    at least 5 minutes to discharge the intermediate circuit capacitors.
•   Measure with a multimeter to ensure that no voltage is present.
    •   Impedance should be at least 1 MΩ.
    •   Voltage should be close to 0 V between inverter phases L1, L2, L3 and frame, and
        between module terminals Brk+ and Brk-.
•   Do not make any insulation or voltage withstand tests on the inverter or on the inverter
    modules.
Note:
• The DC connection terminals Brk+ and Brk- carry a dangerous DC voltage of up to
   800 V.
•   Depending on the external and internal wiring, dangerous voltages of 115 V to 230 V
    may be present at the different terminals in the auxiliary circuit.
•   At the inverter input, the photovoltaic cells generate DC voltage even at low intensity
    of sunlight.
                                                                                   Safety 9

 Grounding
These instructions are intended for all who are responsible for the grounding of the
inverter.

       WARNING! Ignoring the following instructions can cause physical injury or death,
       increased electromagnetic interference and equipment malfunction.

•   Ground the inverter, motor and adjoining equipment to ensure personnel safety in all
    circumstances, and to reduce electromagnetic emission and interference.
•   Make sure that grounding conductors are adequately sized as required by safety
    regulations.
•   When shielded cables are used, make a 360° high frequency grounding of cable
    entries at the cabinet lead-through to suppress electromagnetic disturbances. In
    addition, connect the cable shields to protective earth (PE) to meet safety regulations.
Note:
• The power cable shields are suitable for equipment grounding conductors only when
   adequately sized to meet safety regulations.
•   Standard IEC/EN 62109, 5.2.5 requires that as the normal touch current of the inverter
    is higher than 3.5 mA AC or 10 mA DC, you must use a fixed protective earth
    connection.
•   A four-conductor system is allowed for input cabling, but shielded symmetrical cable is
    recommended. To operate as a protective conductor, the shield conductivity must be
    as follows when the protective conductor is made of the same metal a the phase
    conductors.

            Cross-sectional area of       Minimum cross-sectional area of the
            the phase conductors          corresponding protective conductor
            S (mm2)                       Sp (mm2)

             S ≤ 16                       S

            16 ≤ S ≤ 35                   16

             35 < S                       S/2

•   Automatic disconnection of the supply must be provided in case of discontinuity of the
    protective earthing conductor.
•   A second protective earthing conductor of the same cross-sectional area as the
    original protective earthing conductor must be provided.

About this chapter
This chapter provides an overview, operation principle and hardware description of the
ACS355 Solar pump inverter.

Solar pump inverter overview
The ACS355 solar pump inverter is a low voltage AC drive of 0.3 to 18.5 KW rating
designed to operate with energy drawn from photovoltaic cells (PV). The inverter is
customized to operate in dual supply mode, so the grid connected supply is used in the
absence of energy from PV cells. The inverter functions with the latest in technology
maximum power point tracking (MPPT) algorithm to derive maximum power from the PV
cells at any instant.
The inverter is specifically designed to meet the requirements of pump manufacturers and
the original equipment manufacturers (OEM). For more details of the solar pump inverter
features, see section Program features, page 31.

 Control modes
The solar pump inverter operates in local control mode and in remote control mode
identical to the ordinary ACS355 drive.
 • Local control—interfaces through the panel.
•   Remote control—interfaces through external control signal. For the external control
    through digital input, refer the Default I/O connections, page 22.
16 Operating principle and hardware description

To switch between local and remote control modes use the LOC/REM key on the control
panel. For more information, see section How to start, stop and switch between local and
remote control in ACS355 user’s manual (3AUA0000066143[English]).
Note: Ensure that the inverter is in local control before starting or stopping the inverter
using the control panel.

 Control panels
The solar pump inverter works with either of the two different control panel types:
• Basic control panel—provides basic tools for manual entry of parameter values.
•   Assistant control panel—includes pre-programmed assistants to automate the most
    common parameter setups and provides language support.
For more information, see section Control panels in ACS355 User’s manual
(3AUA0000066143 [English]).
See Start-up procedure section for information on Viewing or Editing parameter values
using control panel.

MPPT overview
 Theory
The solar pump inverter uses the maximum power point tracking (MPPT) control program
to improve the efficiency of solar energy systems. The output of the photovoltaic (PV) cell
is proportional to its area and intensity, while the output voltage is limited by p-n junction
from 0.6 to 0.7 V. Therefore when the output voltage is constant, output power is
proportional to intensity and surface area. The current and voltage at which the PV cell
generates maximum power is known as the maximum power point.

 Operation
The MPPT controller follows different strategies to derive the maximum power from the PV
array. The internal MPPT algorithm is used to derive maximum power from the PV cell at
any instant. This is achieved by modifying the operating voltage or current in the PV cell
until the maximum power is obtained.
When the output voltage is zero, the PV cells create short circuit current. If the PV cells are
not connected to any load, the output voltage is equal to the open circuit voltage. The
maximum power point is obtained at the knee of the I-V curve. See the I-V characteristics
shown below.

                          Vpvn

The I-V curve is not constant since intensity and temperature changes during day time.
Under constant temperature, current changes linearly with intensity and voltage changes
logarithmically with intensity. Since the voltage variation is small with respect to intensity
changes, maximum power varies proportionally with intensity.

Dual supply mode
The solar pump inverter operates in dual supply mode either with a three phase input
supply from the grid or with DC input supply from PV cells. A four-pole changeover switch
enables switching between the two supply modes. At a given time only one supply (PV cell
or grid) will be connected to the drive.

Start-up and controls

About this chapter
This chapter describes the start-up operation of the solar pump inverter.

Start-up procedure
The start-up procedure to set up the solar pump inverter is similar to the ordinary ACS355
drive. See section Starting up the drive in ACS355 User’s manual
(3AUA0000066143 [English]).

 Selecting the Auto/Manual mode
•   In auto mode, the inverter does not need any manual start/stop input.The inverter
    starts automatically if current DC bus voltage is more than the start DC voltage set in
    parameter 6003 START DC VOLT. To use the auto mode, set the parameter 6001
    AUTO/MANUAL SEL to AUTO [0].
•   In manual mode, the drive starts by external connections to either of the digital inputs
    common DI1, DI2 or DI3 pins as shown in Default I/O connections. The inverter waits
    for the activation of digital inputs defined in parameter 6002 MANUAL START CMD. To
    use the manual mode, set the parameter 6001 AUTO/MANUAL SEL to MANUAL [1].
Note: Only one input can be selected at a time.

About this chapter
This chapter describes the pump control features of solar pump inverter. Each feature
includes a list of related user settings, actual signals, and/or fault and alarm messages.

Dry run function
The solar pump inverter trips to a DRY RUN when the water flow is not available at the
pump inlet or when a blockage occurs in the pump. During these conditions the inverter
consumes less current than the minimum load current (6016 MIN LOAD CURRENT) or the
actual motor current is lower than the minimum load current for the defined trip time.
Note: The dry run function is disabled during the initial start up time.

32 Program features

Boost voltage factor
Boost voltage factor enables increasing the pump speed. When the actual DC bus voltage
is greater than the boost voltage, the pump speed increases by a defined boost factor. The
MPPT algorithm achieves this increased speed limit only if the actual DC bus voltage is
appropriate to the boost factor.

 Settings

 6009 BOOST FACTOR                    Factor at which the inverter functions the best.

Voltage limits
The solar pump inverter operates within the voltage limits defined for PV cells and beyond
these limits the inverter trips. At maximum voltage limit, the inverter trips to a PV MAX
VOLT fault. Below the minimum DC voltage limit, the inverter stops modulating.

                                 VOLT).

Speed limits
The ACS355 solar pump inverter operates within the defined speed limits set in the group
60 PUMP CONTROL parameters.
• Minimum pump speed—Below this value, inverter stops the pump operation. The
    inverter restarts automatically only after the 6019 FAULT RESET TIME, see page 57.
    This operation of the inverter prevents the pump from running at a low speed (where
    the pump capacity drops and is near zero).
•   Maximum pump speed—The pump operates within this speed limit defined by MPPT
    in 6007 PUMP MAXIMUM SPD, provided that the maximum speed limit of the inverter
    in 2002 MAXIMUM SPEED is equal to or higher than this value.
Note: Ensure that the pump speed is always defined within the allowed speed limit of the
inverter.

Flow calculation
The flow calculation function provides a reasonably accurate calculation of the flow without
the installation of a separate flow meter. The function defines the flow estimate using the
pump performance curve and drive actual load. The PQ (power/flow) performance curve
enables calculating the flow output from the pump. The performance curve is provided by
the pump manufacturer. The user saves five operating points (P,Q) of the performance
curve to drive parameters.

The solar pump inverter records and stores the flow rate on each day and provides the
required data for current day and current year.
Note:
• The flow calculations are available only with assistant control panel. Ensure that the
   assistant control panel is attached before starting the inverter.
•    Do not use the flow calculation function outside the normal operating range of the
     pump.
•    Do not use the flow calculation function for invoicing purposes.
•    Ensure that power and flow points are in incremental order with non-zero values.

PID control macro
The ACS355 solar pump drive is designed to work with MPPT algorithm. Hence the PID
control macro is disabled and similarly when the PID control macro is enabled, the MPPT
algorithm is disabled.
See section PID control macro in ACS355 user’s manual (3AUA0000066143[English]).

Pump cleaning
The solar pump inverter provides the pump cleaning function to prevent solids from
building up on pump impellers or piping. The function consists of a programmable
sequence of forward and reverse runs of the pump to shake off any residue on the impeller
or piping.

The cleaning sequence can be activated only in the manual mode of operation. The
cleaning sequence starts in the forward direction and follows the reverse direction. This
cycle repeats three times. If any intermediate fault occurs, the pump cleaning function
stops.
