WebdynSunPM, the brain of the modern photovoltaic system
The photovoltaic industry is undergoing a profound transformation
Photovoltaics is undergoing a profound transformation. Long considered mere electricity-generating units, solar installations are now becoming true smart energy systems. With the rise of self-consumption, new constraints imposed by grid operators, and the need to optimize energy efficiency, system management has become essential.
In this context, the WebdynSunPM solution has emerged as a central component of modern photovoltaic projects. More than just a monitoring tool, it acts as the true brain of the system
Photovoltaics enters the era of smart control
For many years, photovoltaic systems operated on a relatively simple principle: generate and feed available energy into the grid. This passive approach met the needs of a market that was still largely unregulated.
But the energy landscape has changed dramatically.
Today, operators must contend with:
- the growing saturation of local power grids,
- limitations imposed by grid operators,
- the rise of self-consumption,
- the challenge of controlling energy costs,
- and increasingly strict regulatory requirements.
A photovoltaic system can therefore no longer operate autonomously and disconnected from its environment. It must be capable of analyzing the energy situation in real time and adapting its behavior instantly.
This is precisely the role of smart control systems.
WebdynSunPM: an advanced energy control gateway
The WebdynSunPM acts as a centralized energy controller capable of continuously monitoring and adjusting the operation of a photovoltaic system.
Its role is based on three essential functions
1. Collecting field data from:
Energy meters
Inverters
Sensors
Consumption measurement systems
Third-party equipment via industrial protocols
This data collection provides a comprehensive and instantaneous view of the site’s energy behavior.
2. Analyzing energy flows in real time
Once the data is centralized, WebdynSunPM analyzes:
- photovoltaic production,
- building consumption,
- grid feed-in flows,
- deviations from defined targets.
This embedded intelligence enables the system to anticipate variations and make decisions automatically.
3. Dynamically controlling production
The solution then adjusts photovoltaic production based on the site’s needs and grid constraints:
- power limitation,
- zero-injection management,
- self-consumption optimization,
- dynamic regulation,
- adaptation to external setpoints.
The system is thus able to react instantly to load variations and the demands of the power grid.
A concrete response to the new challenges of photovoltaics
Zero Injection | Autoconsumption | Power Regulation | EMS | Modbus Slave
Zero injection: ensuring safe operation
Many industrial or commercial sites are not authorized to feed electricity into the grid. Without control, a simple drop in consumption can lead to unintended grid injection.
Thanks to WebdynSunPM, photovoltaic production is automatically adjusted to maintain a constant balance between production and consumption.
Result:
- regulatory compliance,
- elimination of the risk of penalties,
- secure operation.
Optimization of self-consumption
Self-consumption is now at the heart of corporate energy strategies. Generating energy is no longer enough: above all, it must be consumed intelligently.
WebdynSunPM enables:
- production to be tailored to the site’s actual needs,
- energy losses to be minimised,
- and the value of the electricity generated to be maximised.
This approach directly improves the overall profitability of the installation.
Power regulation and grid stability
Electric grids are becoming more sensitive to increases in installed photovoltaic capacity. Grid operators now require installations capable of rapidly adjusting their output.
WebdynSunPM meets these new requirements through real-time dynamic control that ensures:
- stability,
- responsiveness,
- compliance,
- operational flexibility.
EMS
Aujourd’hui l’ajout du stockage dans les projets photovoltaïques est rendu nécessaire pour garantir la rentabilité des installations. Charger et décharger au bon moment est un enjeu majeur d’un EMS intelligent.
Today, adding storage to photovoltaic projects is necessary to ensure the profitability of installations. Charging and discharging at the right time is a major challenge for a smart EMS.
WebdynSunPM enables:
- optimizing photovoltaic production in the event of a surplus
- offsetting consumption peaks
- defining a smart control strategy
Modbus Slave Functionality
With the development of smart grids, grid operators need to control photovoltaic power plants of all sizes using third-party equipment.
WebdynSunPM allows interfacing with any Modbus TCP Master (SCADA) equipment by acting as a Modbus Slave:
- access to any read data
- script control
- configurable exchange table
A solution designed for integrators and operators
Beyond its technical performance, WebdynSunPM also simplifies the day-to-day operation of installations.
Operators benefit from:
- clear monitoring,
- better visibility of energy flows,
- operational history,
- analysis and diagnostic tools,
- easier maintenance.
Integrators, for their part, have a solution capable of adapting to a variety of architectures and projects of different sizes.
Photovoltaics is shifting from passive production to controlled production
The photovoltaic market is entering a new phase of maturity. Projects are no longer limited to installing solar panels: they must now incorporate intelligence, flexibility, and communication.
In this context, WebdynSunPM becomes an essential functional building block.
It enables the transformation of a conventional photovoltaic installation into a smart energy system capable of:
- optimizing its production,
- complying with grid constraints,
- improving profitability,
- and ensuring long-term operational security.
Modern photovoltaics now demand much more than simple energy production. Systems must be able to communicate, adapt, and respond in real time to technical and economic constraints.
Thanks to its advanced monitoring and control capabilities, WebdynSunPM stands out as the brain of next-generation photovoltaic systems.
It guides operators toward smarter, more efficient, and fully controlled production.
Enter the “ethernet” or “modem” connection type:
For an ethernet configuration, make sure the IP parameters are compatible with server access according to the concentrator local network configuration. For an ethernet connection, the configuration must be compatible with the concentrator’s local network topology so that it can access the servers. This configuration is done from the “Networks” configuration page (see section 3.2.2.3: “Networks”).
For a modem connection, the modem configuration must be correct before a connection can be set up. This configuration is done from the “Modem” configuration page (see section 3.2.2.4: “Modem”).
The parameters for the servers to be configured are at least the following:
Therefore the following fields need to be configured: “Interface”, “Type”, “Server type”, “Address”, “Port”, “Login” and “Password”.
The other fields can be left at the default values subject to the directories having been properly created beforehand. See section 3.1.2: “Configuration files” for more details.
Wait. The concentrator will reboot using its factory configuration.
