Inverter communication Monitoring software for photovoltaic systems
Solarworx is available for PC Worx libraries and is used to implement photovoltaic projects. For example, it includes complex blocks for solar altitude calculation and monitoring photovoltaic trackers. Drivers for data loggers and interfaces for inverters complete the overall package.
To keep the engineering outlay for the startup of photovoltaic systems to a minimum, we are constantly developing new drivers and function blocks for the connection of environmental sensors and for photovoltaic tracking systems.
- Reduced engineering with preprogrammed function blocks
- Reliable operation of the photovoltaic system due to comprehensive function block tests
- Flexibility with the international IEC 61131 programming standard in use
- Continuously growing range of functions with regular new additions to the block library
Use of the Solarworx software library
In order to guarantee the cost effectiveness of photovoltaics systems, all components must reliably withstand challenging conditions over long periods of time. However, even the best hardware can only be commissioned in a straightforward way, without errors, if the required software is fully developed and tested.
Existing function blocks enable the use of different inverters or energy measuring devices without laborious analysis of the protocols. Thus, when it comes to programming, the focus can be placed on data processing and communication.
Function blocks of the Solarworx software library
Phoenix Contact provides software libraries specially for photovoltaic systems, which are continuously expanded by adding functions.
Ready-made function blocks enable straightforward communication with inverters. They enable, for example, general inverter information, such as serial numbers or the inverter type, to be read out. Furthermore, photovoltaic tracking systems can also be controlled and all standard AC and DC measuring values determined, e. g., the current feed-in power or yield. Even acquiring inverter-specific event and status messages is no problem. The portfolio is completed with function blocks and a program template for controlling the reactive power feeding of a photovoltaic system.
Phoenix Contact supports system integrators and users that use the SunSpec® open standard, with function blocks compatible with this.
The SunSpec® Alliance is a global user organization of over 70 participants from the solar industry. In order to enable Plug and Play solutions, it pursues the goal of defining communication standards. This reduces the costs and complexity of solar-powered systems and makes them more attractive to investors.
