Notes on this manual
This guide describes all the WebdynSunPM product characteristics.
Its purpose is to help operators install and configure 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: Configuration
➢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 group
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.
We recommend calling on specialised and trained persons to install and commission the
the list of partner portals.

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 confidentiality 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.
Operating principle
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 configured by simply sending text message commands, but also using
the embedded web pages.
Specific scripts can be created for installations requiring specific functions.
