Environmental Statement
The grid connected PV inverter of Fimer reduce raw material consumption and scrap throughout their long working
lifetime. In typical applications, these positive environmental effects far outweigh the negative impacts of product
manufacture and end-of-life disposal.
Product packaging is of good quality and can be re-used. All the products come in strong cardboard cartons which
themselves have a high recycled fibre content. If not re-used, these containers can be recycled. Polythene, used on the
protective film and bags from wrapping product, can be recycled in the same way. Fimer’s packaging strategy favours
easily recyclable materials of low environmental impact, and regular reviews identify opportunities for improvement.

1 INTRODUCTION
Dear Customer,
The sensor box is an optional accessory specifically designed to be used in conjunction with the
R25-R35-R50-R55 inverters manufactured by Fimer , and it is marketed by Fimer. This document
is a supplement to the User Manual for PV inverters.
Please read and observe the safety information and danger notices contained in that manual. A
complete version of the User Manual for the inverters can be found on the CD supplied with each
inverter. Furthermore, we ask you to read and observe the handling instructions given in the manual
supplied with the SI sensor from Mencke&Tegtmeyer.
Please comply with all instructions and information of relevance to and essential when handling
pieces of technical equipment.

7 Option: Comparison of Yields from Inverters by
Sensor Box Module
7.1 Functional Description
Each inverter is equipped with an integrated yield monitoring function. This function is based on
the comparison of yield data from one inverter with an irradiation sensor connected or from an
installation comprising at least 2 inverters that are networked by means of a master-slave network.
7.2 Requirements
✦ Irradiation and module-temperature sensors connected and set.
✦ Suitable installation position and geographical orientation for the sensor box (same
inclination, orientation and shadowing as the modules)
✦ Activation code (available from FIMER for an additional charge)
Note: The sensor and inverter data can be compared without the activation code. It is also possible
to read out the annual sensor logger and the annual energy logger without the activation code. If you
do have and enter the activation code, an automatic check takes place and an alarm is output.
7.3 Parameter configuration and setting
The following parameters must be entered:
Parameter number 214: Module efficiency
Menu Environment
Short Description META
Unit %
Accuracy 0,1%
Enter the efficiency of the modules here.
Nota: When making this entry, make sure that you enter either the module efficiency here and the
total module surface area for parameter 215 or the cell efficiency here and the total cell surface
area for parameter 215.
Parameter number 215: Module surface area (of PV installation)
Menu Environment
Short Description MFL
Unit m2
Accuracy 0,1m2
Enter the module surface area in m2 here.
Note: When making this entry, make sure that you enter either the module surface area here and the
module efficiency for parameter 214 or the cell surface area here and the cell efficiency for
parameter 214.
Parameter number 218: Module temperature coefficient
Menu Environment
Short Description MTK
Unit %/°C
Accuracy 0,01%/°C
________________________________________________________________________________
_____________________________________________________________________________
6
Enter the temperature coefficient of the output of the PV generator here. You can find the values in
the data sheet of the modules.
Note that the temperature coefficient is negative, but that you have to enter a positive figure here.
Example: The modules used have a temperature coefficient of γ (P_MPP) = -0.33%/°C. In this case
enter the value 0.33%/°C.
Parameter number 280: Yield variation alarm threshold
Menu Installation Monitoring
Short Description EAW
Unit kWh/kW
Accuracy 0,500 kWh/kW
Under this parameter, you enter the value for variation between the yield of the inverter and the
"theoretical yield" of the sensor or between the yields of all the inverters in the installation,
referenced to the nominal DC output. If this value is overshot, an alarm is activated.
Parameter number 283: Activation code for yield monitoring
Menu Installation Monitoring
Short Description FSC
Default value 0
Enter the code given to you by FIMER.
7.4 Data evaluation
Parameter number 220: Sensor output
Menu Environment
Short Description PSENS
Unit W
✦ The instantaneous output of the PV generator to be expected in theory is calculated here on
the basis of the irradiation sensor reading, the total module surface area, the module
efficiency, the module temperature and the output temperature coefficient of the modules.
Note that this theoretical output always deviates greatly compared with the actual output of the PV
generator. This is due to the different materials used in the cells of the generator and sensor,
different temperatures, and possible shadowing or soiling. Parameter 220 serves as a rough guide
or interim value for display under parameters 216 and 219.
Parameter number 216: Yield of the sensor today
Menu Environment
Short Description SET
Unit Wh
The day yield meter of the sensor displays the "day yield" calculated for the sensor. It is used to
compare the actual day yield (see parameter 8) with the theoretical, calculated "yield" of the sensor.
Based on the module surface area, module efficiency and module temperature coefficient, we
recommend that after a certain length of time (e.g. 1 to 2 months) you set the "day yield of the
sensor" manually such that the sensor yield value is roughly equal to the actual yield. This will
enable you to detect module or string failures (or failure of the sensor) if they arise.
________________________________________________________________________________
________________________________________________________________________________
7
Parameter number 219: Total yield of the sensor
Menu Environment
Short Description SEG
Unit KWh
Total yield meter of the sensor since its start-up.
This meter displays the "sensor yield" calculated since start-up. It is used to compare the actual total
yield (see parameter 12) with the theoretical "yield" of the sensor.
8 Annual Sensor Energy Logger
The inverter records the "day yield" of the sensor for every day of the year (see parameter 216). The
inverter is equipped with a memory that stores the yield for 365 days. This memory is cyclical, i.e.
after a year, it overwrites the old values stored.
By comparing the annual sensor energy logger with the annual energy logger, you can detect
variations and errors, such as module failures, string failures, shadowing or soiling.
8.1 Reading out the annual sensor energy logger by remote PC
8.1.1 Using FIMERNet software
The easiest and most convenient way to read out the sensor data is to use our FIMERNet program.
In the "Connection Manager" tab, activate the "With Sensor" option for the inverter to which the
sensor box is connected.
This results in the sensor data being transferred and displayed when you input the instantaneous
data in the "Annual Energy Logger" tab.
In addition, you can get the data logger to record the parameters in which the sensor readings are
saved and display them in the "Data Logger" tab.
If you would like more information aboutFIMERNet, please read the FIMERNet User Manual.

8.1.2 Using HyperTerminal
Read out the annual sensor energy logger using HyperTerminal and command /8. Entering
command /9 displays the actual yield and the sensor yield at the same time..
9 Alarm
If the inverter detects a yield variation, it continues to function but an acoustic and a visual alarm
signal are output.
The LCD display switches on. The word "Alarm" and the cause of the alarm are displayed
alternately in the third line of the basic (start) screen. The LED on the cover of the inverter flashes
red and green alternately.
The alarm horn integrated in the inverter emits an intermittent alarm tone. It sounds for half a
second every second. The alarm horn can be switched off by pressing any button.
Switching off the alarm.
Parameter number 279: Alarm configuration
Menu Installation Monitoring
Short Description CFGW
Default Value 383
To switch the alarm off Set the parameter to 0.
