Make your PV systems more efficient

PV monitoring is becoming increasingly important. After all, photovoltaics is the most widely used application today for replacing traditional power plants. However, photovoltaic plants need to be monitored and maintained in order to reduce the electricity production costs (levelized cost of electricity/LCOE) of the plants. Our solutions for PV monitoring allow you to precisely monitor your PV plants – with low manual effort required 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!


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 that 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 was designed to monitor the current and voltage of the individual strings as well as the 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

String monitoring with Transclinic xi+

Constant PV monitoring of your photovoltaic plant

The Transclinic xi+ series continuously monitors the performance of single strings or groups of strings as well as the voltage of your photovoltaic system, enabling detailed monitoring. Negative influences that reduce the power output can be detected immediately so that fast repairs or adjustments can be made to the system.

There's no need to oversize your system just to ensure the expected power output. Good PV monitoring of your plant guarantees efficient, optimized power output without oversizing the plant. With more than 115,000 systems sold around the world over the last twelve years, the quality, long lifetime and optimal performance of the Transclinic xi+ product range in diverse environments is assured.

  • The standard PV monitoring system can monitor individual strings with up to 16 inputs and a max. Isc of 25 A per input.
  • The double string monitoring solution allows two (or even three) strings to be monitored via one channel.
  • Transclinic 16i+ 1k5 H enables the measurement of 25 A per input even at 70°C with a precision of ±1% (voltage/current).
  • RS485 SPD on board – specific surge protection for RS485 interfaces is already integrated

Status monitoring for all key process parameters is a vital component of any high-quality condition monitoring solution. It is important because it is used to prevent excessive temperatures and allow users to detect and correct wear and malfunctions early on. You can only control your PV plant optimally and achieve the highest efficiency if you have a good overview of your power plant and the processes going on inside it. Take a look at our reference projects to find out more about condition monitoring as a success factor and how we implement it.

Product highlights

With our solutions for photovoltaic monitoring, you'll increase the electricity yield of your PV plants, optimizing electricity production costs (LCOE) and the performance ratio (PR) and return on investment (ROI) of your system.
