Photovoltaic string current monitor CcM 1500 SHUNT

We are now broadening our range of individual string monitoring devices to achieve the highest possible measurement accuracy, avoid obstructions to the flow of current, simplify the installation and guarantee a better performance of the installation. Thanks to its groundbreaking new connection concept and the innovative measuring and manufacturing technology, this new device reduces both, space and installation costs. (C.E./U.L. Certification).

 

What is the photovoltaic string current monitor CcM 1500 SHUNT?

CcM 1000/1500 Hall is a measuring device designed to monitor current flowing from the first or second level combiner boxes all the way to the inverter. Its design replaces a multi-phase electric distribution busbar. We recommend that it should be installed during the assembly of the first level combiner box.  

Features of current monitor CcM 1500 Shunt

The device is able to measure string box output voltage without any additional systems and observes the voltage drop by comparing the voltage of the string box with that of the inverter input. In order to maximize space and minimize final installation costs, it is possible (always on request) to adapt the size of the device, modify the PCB and adapt the number of channels. In this manner, we can obtain devices with a number of channels adapted for each project. Possible configurations include 10, 12, 14, 16, 18, 20, 22 and 24 channels.

 

Where is the CcM 1000/1500 Shunt installed?

Monsol 1000/1500V (Shunt) monitoring modules should be installed in watertight enclosures that comply with IP65 standards outdoors and IP55 standards indoors to be protected from corrosion and humidity
