Accessories for solar plants
The big and small helpers in your plant

Inverters are an important component of your systems, but there are also other important features that contribute to improving your system. An overview can be found below:


Parkcontrol and monitoring made easy

  • Professional, based on PLC
  • REFUlog connected
  • Customizable to your needs


Almost every solar plant needs some kind of monitoring or remote control solution. The modular REFUcontrol solution is based on the proven, industry graded PLC solution from Phoenix Contact. Standard tasks like inverter data forwarding of RS485 connected solar parks to the REFUlog monitoring portal or remote active power control can be used out of the box. All kinds of individual requirements for professionnal park management with active and reactive power control, direct marketing and remote control can be realized with the support of qualified Phoenix Contact Solution Partners.

DC CombinerBoxes
The boxes for more flexibility

  • Made in Germany
  • Cost-optimized
  • Customized options


Besides our REFUsol inverters there may be additional components necessary or useful in a PV plant. You can choose these from our extensive accessory portfolio. Profit from cost-optimized products that are pefectly matched to your plants thanks to a wide variety and individual configuration options. Rely on proven quality 'Made in Germany'.

The CombinerBox allows the string collection near the solar modules, in order to connect the inverter with an efficient homerun in aluminum or copper. Thereby both – a decentralized as well as a centralized – installation of the string inverters is possible.

Temperature and irradiation sensor
More data – better quality information

  • Precise measurement
  • Full yield control
  • Sturdy and weatherproof


Measure your PV system’s performance. The external temperature and irradiation sensor accurately captures the two ambient parameters, which together have an impact on the current performance of a PV system: temperature and irradiance.

It is of course compatible with all REFUsol inverters. The active temperature compensation function of the device increases its measuring accuracy; the extended measuring range up to 1,500 W/m2, the individual calibration to the standard measuring signal and the possibility of measuring the module temperature make the sensor a powerful data collector.
The inverter integrated data logger records the temperature and irradiation values and passes them on to the REFUlog monitoring portal. With these additional values, you can display the operating status of your PV system more precisely and detect faults more quickly. In addition, the performance ratio is continuously calculated in REFUlog using this sensor data.

Plugs, fuses and more
The little helpers
