About This Document
Purpose
This document introduces the best installation practices for the configuration set up of Soluzione
Solare sensor – E VMETER-485 PRO by briefly mentioning the recommended and not
recommended practices during the field installation. This document also gives clear instructions
related to troubleshooting of MODBUS 485 configurations.
Intended Audience
This document is intended for consumers of Soluzione Solare sensors and qualified electricians.

1.Recommended to do during the installation- Mechanical
1. Recommended to do during the installation
1.1 Mechanical
(1) In order to get the right fit of male and female side of the connector pin, turn the male side
of the connector less than 360° for finding the right position.
(2) After finding the right position, tighten the connection only by rotating the steel ring and
make sure you do not rotate the connector.
(3) It is best recommended to just place it in a shaded area that is sheltered from rainfall.
(4) The recommended standard height above ground for E VMETER Pro is 1.5 meters. It need
to be installed in an area that is open and level, ideally above trimmed grass which would
allow for ventilation.

1.2 Electrical
(1) For proper cable connections, please refer to the instruction manual that comes along with
the E VMETER-485 Pro device and also you can find it in this following link:
(https://www.soluzionesolare.com/documenti/Datasheet_ NVM T R_PRO_485_eng.pdf)
(2) Power supply should be connected with the exact pins as the manual indicates and the
suitable voltage to be supplied is 7,5-28 Vdc.
(3) For the connections, we suggest you to use twisted cables which are shielded.
(4) Always connect the shield to the ground.
(5) If there is no signal received from the RS485 port, try to swap the cables A and B and check
again if the signal is received.

1.Recommended to do during the installation- Firmware
1.3 on!guration software/Firmware
(1) For the first time after unboxing the E VMETER-485 Pro, connect it using the default
settings (Address = 1, Baud rate =19200 and Serial configuration = 8 1).
(2) After turning on the E VMETER-485 Pro, please wait for 5 seconds before connecting it to
the SM config software in order to achieve a proper configuration.
(3) In case, if you need to change the default settings value, use the SM config software by first
connecting the device with the default setting values mentioned in point 1 and then change
them to the required values.
(4) After changing the values click these buttons in the sequence as mentioned 1) Read all 2)
Write all 3) Save and 4) Reset

1.Recommended to do during the installation- Firmware
(5) Please ensure you leave a time gap of 2 seconds in between clicking each buttons.
(6) We recommend you to place a label on the E VMETER-485 Pro with the new settings in
order to remember the modified new settings.
(7) Bit rate should be set low in case of long wire connections and environment with more
electrical noises.

2. ot recommended to do during the installation
2. Not recommended to do during the installation
1. It is not recommended to place that sensor in an area where the sun’s rays strike it directly. It
is best to just place it in a shaded area that is sheltered from rainfall.
2. Do not place the sensor in rocky terrain, dusty environment or dirt.
3. Do not place the sensor on a steep slope because of the effect gravity affects water and air
flow rate.
4. Avoid presence of heating and cooling sources as well as nearby obstructions in order
achieve optimal readings.
5. Avoid areas where water residue collects or pools.
6. DO OT Install your sensor under a tree or any kind of vegetation.
7. Do not bend the connectors or cables and it is not recommended to place it on sharp edges.
8. It is not recommended to use dusty sensors which could show a deviated readings. Always
clean the sensors to ensure optimal readings.

3.MODBUS troubleshooting
3.MODBUS troubleshooting
(1) For troubleshooting and information about MODBUS protocol kindly visit
https://modbus.org/ even for recommendations on polarization. Kindly check the general schema of
the MODBUS RS485 protocol given below.
In case if you have a bad communication and in order to have a right polarization, follow this
formula for calculating the voltages between B+ and A- for finding out if the connections satisfy the
condition
VB+ - VA- ≥ 0.2 V
Polarization network
If the above condition is not satisfied, please refer to the polarization network to be inserted on the
bus
B+ potential value:
VB+=(R2+R3)V+
(R1+R2+R3)
A- potential value:
VA+=(R3)V+
(R1+R2+R3)
Where R1, R2 and R3 are the three resistors.(refer to the example images)
V+ is the supply voltage

3.MODBUS troubleshooting
If the Datalogger does not have this RS485 polarization net, the user has to do the proxy from input/
output.
If the lines are longer user could implement the polarization and if the line is more longer it is
suggested to provide with a local power supply which should be polarized.
Examples of local power supply for less than 5 devices connected is given below.
Example for 12V
Example for 24V

3.MODBUS troubleshooting
(4) If you have troubles with MODBUS connection which can happen if you have more than a
couple of devices from different manufacturers connected in the same RS485 line, it is suggested to
test the values along the RS485 cable. If you find it difficult to test the values along the line,
MODBUS test box can be used. Please check the output voltage levels and impedance of each
terminal using the MODBUS test box.
