Current and Voltage Monitoring in Photovoltaic Installations

Fewer Decentralized Measuring Points Required in Solar Parks

Solar parks are an essential component of the global energy transition. As a result, their expansion marches on relentlessly. For system operators, the priority is always the efficiency of their solar parks: Achieving higher output and better efficiency while keeping costs low. Transitioning the system voltage from 1,000 V DC to 1,500 V DC appears to be the logical consequence. Operators can achieve both economic and safety advantages by using high quality high-voltage measurement technology in the inverter stations.

Inverters: The Cornerstone of Every Photovoltaic (PV) Installation

Inverters are a key component of every solar park. They convert the direct current of the PV module into alternating current and then feed it into the power grid. Moreover, inverters monitor essential parameters of the installation, such as voltages, currents, and power. This data is indispensable for purposes such as maximum power point tracking (MPPT), which can be used to optimize the performance of individual solar cells. Moreover, the transducers used in the inverter stations detect power drops caused by line interruptions and other faults at an early stage.

Return on investment

  • Current and voltage measuring technology installed centrally in the inverter on the basis of signal conditioners increases efficiency and saves money at the same time since it makes decentralized measurement unnecessary.
  • Central signal conditioner arrangement simplifies the station concept development and also results in cost advantages.
  • The precise measurement of total current makes it possible to detect defective station components early on, thus avoiding yield losses and increasing the safety and reliability of solar power stations.
  • High operational safety with galvanic isolation of up to 1000 V or 1800 V AC/DC
  • Calibrated switching of up to 16 input and output ranges offers flexibility and reduces storage costs.
