Solution for programming solar projects

• For the reliable operation of photovoltaics systems, all components must withstand challenging conditions.
• Ready-made function blocks support simple startup of inverters or energy measuring devices.
• System integrators and users benefit from SunSpec^®-compatible function blocks.

Phoenix Contact provides software libraries specially for photovoltaic systems, which are continuously expanded with functions.

Ready-made function blocks enable straightforward communication with inverters. For example, they enable 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., momentary 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. Official certification, by the SunSpec® user organization, will take place over the course of 2016.

The SunSpec® Alliance is a global user organization of over 70 participants from the solar industry. Its objective is to define communication standards that enable Plug and Play solutions. This reduces the costs and complexity of solar-powered systems and makes them more attractive to investors.
