About this Document
This guide describes all the WebdynSunPM product characteristics.
Its purpose is to help operators install and congure their WebdynSunPM and to allow operators to
include collected data in their IS.
This manual is split into six separate sections:
• Section 1: General presentation
• Section 2: Installation
• Section 3: Conguration
• Section 4: Operation
• Section 5: Tools & diagnostics
• Section 6: FAQ
Scope
This technical description is valid for WebdynSunPM concentrators as from hardware version V1 and
software version V3.0.0.
Target Audience
This guide is intended for all people involved in photovoltaic system supervision, in particular people in
charge of local or remote installation maintenance, as well as for the developers of portals designed to
use the sent data.
It is recommended to entrust the installation and commissioning of the WebdynSunPM to qualied and
trained persons. Qualied persons must have the following skills:
• Detailed knowledge of network management services.
• Knowledge of IP-based network protocols.
• Knowledge of the specications of the protocols used (Modbus, SunSPec, etc.) and of the
equipment connected to the concentrator.

1. Presentation
1.1 General Description
The WebdynSunPM is a concentrator designed to monitor all types of photovoltaic installation. It is used
to collect, analyse, monitor and control the on site devices.
The collected information (data, parameters, etc.) is formatted before being sent to an Information
System (IS). The concentrator provides the security and condentiality of the exchanged information.
The automation of certain local actions, for example injection or self-consumption is managed using
customisable scripts embedded in the concentrator.
1.2 Principles of Operation
The WebdynSunPM concentrator can be fully integrated into photovoltaic installations. Devices such as
inverters, sensors (pyranometers, temperature sensors, etc.), meters, displays, circuit breakers or relays
can be connected to the concentrator using its many available interfaces. Information readings and
device control are carried out by the WebdynSunPM continuously. The data is regularly formatted and
uploaded to an FTP server and/or sent to an MQTT server using the modem or an Ethernet connection.
The concentrator manages the SFTP and MQTTS protocols to secure exchanges with the servers. The
WebdynSunPM can be congured by simply sending text message commands, but also using the
embedded web pages.
Specic scripts can be created for installations requiring specic functions.

1.7 Safety Instructions
Follow all the safety instructions in this guide.
Failure to follow these instructions can damage equipment and endanger people.
Electric connection:
• All wiring work must be carried out by a specialised qualied electrician.
• Please follow all the safety instructions featured in the manufacturer’s device documentation.
The WebdynSunPM product can be damaged by electrostatic discharges (ESD)
Class 3 equipment: the device operates on safety extra-low voltage (SELV) (50V maximum). The
voltage reduction must be obtained using a safety transformer providing safe galvanic isolation between
primary and secondary.
This equipment is not suitable for use on premises that may host children.
Do not install the equipment near a heat source or at a height greater than 2m.
To clean the product, only use a slightly damp cloth to gently clean and wipe the surfaces. Never
use aggressive chemical agents or solvents that could alter the plastic material or corrode the metal
parts.
It is essential to leave a 20 cm empty space around the antenna to optimise the Modem cell
sensitivity.
1.8 Regulation
The product is compliant with the European directives according to the EU declaration of Conformity
available from Webdyn or from the web site: www.webdyn.com.
