1. Defaults Save Parameter d 05 serves mainly to store entire configurations in permanent flash memory of the inverter as well as to restore written configurations When the inverter is power supplied the configuration parameters specifying the behavior of the drive are kept in an energy dependent operational memory RAM By switch off of the power all parameters from the running configuration are automatically saved in energy independent non volatile FLASH memory By switching on of the power all parameters from energy independent memory FLASH are transferred into operational memory So the inverter configuration is restored from the last switch off This is so called automatic configuration which is preserved and restored automatically without external command Inappropriate changes of configuration parameters could lead to unwanted behavior of the drive compared to the one before the changes In case that multiple changes are done reversion to the previous working configuration could be difficult to do by memory To secure taking out from such unfavorable situation it is foreseen a possibility for saving the backup configuration This configuration is saved in separate zone in flash memory that is not affected by automatic writing at power down It is recommended after change of configuration parameters by reaching well working configuration this configuration to be written as a backup one This can2. L 03 sets the boost frequency value for the U f curve According to the considerations given above Voltage Boost is hardly needed for pump drives so normally L 03 may preserve its default zero value Menu 11 n Solar Control n 00 and n 01 parameters set respectively the P component gain and I component gain of a Proportionally Integral Controller PI Controller which produces the drive output frequency setpoint depending on the measured value of the DC voltage coming from the PV panels Solar Pl controller prevents the drive from drawing too much power from the PV panels in case of insufficient solar radiation So it reduces the output frequency setpoint if the measured PV voltage tends to fall below some critical threshold This Critical Voltage threshold is defined as proportion of the PV voltage under load towards the PV voltage in idle state Open Circuit PV voltage OC So setting the Critical Voltage presumes knowledge of the Open Circuit PV voltage Open Circuit PV voltage can be easily measured by the inverter in idle state But this is true only on condition that there is only one inverter connected to the PV string If there are two or more inverters supplied by common PV string automatic determination of the Open Circuit PV voltage is not possible as there is no guarantee that when some inverter is idle the PV panels are not being loaded by some other inverter Parameter n 02 is used for
3. Multifunctional outputs we find the parameter corresponding to digital output 1 this is parameter F 00 Then we assign the value 3 to F 00 So the output function 3 is assigned to digital output 1 By activating of output function 3 the relay on digital output 1 closes its contacts Example 4 We change the conditions of Example 3 so that activating of output function 3 should open digital output 1 contact and deactivating of function 3 should close digital output 1 In accordance with principal depicted above we assign value 3 100 i e 103 to parameter F 00 So the output function 3 is assigned to digital output 1 but by activating of the function the contact is open and by deactivating it is closed Description of Inverter Menus and Parameters Menu 0 A Setting of inverter output frequency Parameter A 00 Frequency Reference sets the maximal output frequency which the inverter can achieve in case of high irradiance ensuring enough energy flow from the solar panels In lower irradiance conditions the output frequency set point is provided by the Solar PI Regulator which sustains the highest possible output frequency for given irradiance conditions Parameter A 01 Minimal operational Frequency sets a lower limit for the inverter oump operation In poor irradiance conditions the highest achievable output frequency motor velocity might be too low for the pump to ensure any water flow So the motor pump
