USER MANUAL –WebdynSunPM
Version 2.05

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.

USER MANUAL –WebdynSunPM
Version 2.05
préliminaire
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.
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
Recycling:
The nationally enacted European directives covering batteries and waste electric
and electronic equipment govern the actions required to limit the negative impact
of the end of product life.
These products are collected separately. Use an authorised battery collection and processing
centre or contact Webdyn.

Prerequisite
As the WebdynSunPM concentrator’s role is to send the data it collects to an IS, installation
requires knowledge of the concentrator but also of the IS it will upload its data to.
The following elements are required to guarantee a proper installation:
-To have this user manual to hand.
-To have a screwdriver suitable for the connector types available on the
WebdynSunPM.
-To have knowledge of the parameters to connect to the IS information system.
It is also strongly recommended to have the elements described below for any
intervention on site and to install the product.
-To have a SIM card with an activated M2M subscription (data and text messages
(optional)) and knowledge of the supplier’s APN. The SIM card call number can be
useful.
-Use a remote antenna if radio or cellular modem reception is deteriorated.
-To have a PC for the product configuration or update using the concentrator’s Web
interface
