8) Adjusting
criteria:

Specific parameters might be adjusted for optimum operation of the Solardrive:

Parameter

Tuning criterion

C800

Minimum pump speed

When the speed set in

C800

is attained and if the electrical power

absorbed by the motor is too high, the pump might frequently start
and stop when solar radiation is weak. Decrease

C800

accordingly

to obtain smooth operation of the pump avoiding lubrication issues or
overheating conditions. The expected behaviour is that when the
speed value set in

C800

is attained, the pump flow rate is low but not

zero.

P009, P010,
P018, P019

Ramps

If

P009

and

P018

are set too short, especially when the pump inertia

is high, the pump might stop due to weak solar radiation at start, and
impulsive power absorption. If this is the case, increase the ramp
times to get slower start stages. The effects obtained by the time set
in parameter

P009

is stronger when solar radiation is strong. The

time set in

P009

is the minimum time required to attain the maximum

power.

P020

see

Speed Threshold for Initial and Final Ramps

Set

P020

so that the speed threshold for the initial/final ramps is the

same as

C800

if not required otherwise, for example for a 50Hz

motor with 1 pole pair, if

C800

=1500rpm,

P020

=50%.

P800

Minimum Solar Radiation Voltage

This is the DC voltage value required to start the motor. If “Insolation
KO” is not displayed, decrease

P800

and/or check the dimensioning

of the PV field.

If the system restarts often at dawn, increase the values in

P800

and

P801

.

P801

Minimum Solar Radiation Time

If the system restarts often at dawn, increase the value in

P801

to

get a longer delay between two pump start stages and to allow solar
radiation to reach values that make the pump start.

P810, P811

MPPT Minimum Voltage

MPPT Maximum Voltage

Set the minimum and maximum MPPT reference based on the PV
field data considering all ambient conditions (e.g. temperature/solar
radiation). If

P810

is set too low, the pump might frequently start/stop

at dawn or when solar radiation is weak, because the available
power is not sufficient to start the pump even if voltage is applied to
the PV field.

In case the pump frequently stops when solar radiation is high,
increase

P810

to operate the system at higher field voltage values.

P813

Load Curve Exponent

This parameter is the power load exponent vs. pump speed. For
centrifugal pumps or quadratic torque loads, set

P813

=3. For

volumetric pumps or other linear loads, set

P813

=2.

P814, P815

Voltage Regulator Integral Gain

Voltage Regulator Proportional Gain

The proportional gain and integral gain of the voltage regulator
determine the promptness of the response from the field voltage
