PV retrofit combiner boxes

PV retrofit combiner boxes – Portfolio for LCOE

Our PV retrofit combiner boxes with wireless LoRaWAN communications help O&M personnel to allocate and isolate any field problem in a few minutes.

The installation of our PV retrofit combiner boxes makes it possible to obtain data at string level in PV systems with existing, unmonitored PV DC combiner boxes. All without additional work such as trenching and cabling. Wireless communication simplifies installation and avoids additional costs or maintenance work on the communication cables.

Benefits

Detection of problems and abnormal performance at string level
Direct yield optimisation of the PV system by optimising the performance ratio (PR) and increasing the yield
Commissioning easy to install and to setup
Several options and compact designs available for easy commissioning for any PV power plant size

Tested & proven PV boxes

Our laboratory ensures the highest product quality

Our laboratory is accredited in accordance with international standards. It operates independently and is recognised by institutions, registration services, and other institutions and authorities. As a member of the CTDP program, Weidmüller is regularly audited by UL, especially regarding test methods, quality management and documentation.

PV DC combiner boxes are tested according to IEC-61439-2 and are constructed on the basis of the test results as well as assembled for the specific application. This ensures that each of the requirements of the target application is fully met.

Product features

Detect string failures online

With our PV retrofit combiner boxes, operating and maintenance personnel can identify and quickly resolve issues. Data monitoring is reliable and the system recognises string faults online. Corrective measures can be initiated at an early stage.

Reduction of O&M additional costs

String monitoring enables independent evaluation of the plant performance.

Improvement of the performance ratio

The PV retrofit combiner boxes increase the performance ratio (PR). Precise monitoring provides PV power plant operators with all the relevant data they need to find failures quickly and to operate the systems efficiently.
