PV string monitoring systems

Sustainably increase the productivity of PV plants with solar monitoring

PV string monitoring systems

Make your PV systems more efficient

PV monitoring is becoming increasingly important. After all, photovoltaics is today's largest application area when it comes to replacing traditional power plants. However, photovoltaic plants need to be monitored and maintained in order to reduce the electricity production costs (levelised cost of electricity/LCOE) of the plants. Our solutions for PV monitoring allow you to precisely monitor your PV plants – with low manual efforts for monitoring, servicing and maintenance. This ensures that your investments aren't left unattended.

With our solutions for PV monitoring, you can detect anomalies early on, allowing you to improve the LCOE and ROI (return on investment) of your plant. Use your available resources as efficiently as possible and trust in our reliable solutions for PV monitoring!

Product highlights for PV monitoring

With our solutions for photovoltaic monitoring, you'll increase the electricity yield of your PV plants, optimising electricity production costs (LCOE) and the performance ratio (PR) and return on investment (ROI) of your system. In addition, our products enable the ongoing monitoring of individual PV strings or string groups. This minimises downtime and energy losses. With our solutions for PV monitoring, you can save on costs and realize the large-scale expansion of your systems.

PV string monitoring system

Modular PV string monitoring system for up to 32 strings

In the case of utility scale photovoltaic plants, the electrical parameters of the PV strings require constant monitoring. This is the only way owners and operators can maintain the performance and yield of their systems in the long term.

Our new PV String Monitoring System is integrated into the DC combiner boxes of plants with central inverters. It is designed to monitor the current and voltage of the individual strings as well as the current SPD and breaker status in the combiner box.

Thanks to its modular design, the PV monitoring system can monitor up to 32 strings and can measure up to 50 A per string. It is powered by plant current, can communicate wirelessly and has low heat emission.

  • Highly competitive modular string monitoring solution
  • Simultaneous monitoring of up to 32 strings
  • Wireless communication via LoRaWAN® protocol as a plug&play solution
  • Monitoring from 25 to 50 A per string for modules with 8 and 12 strings
