String monitoring

With the monitoring of PV module strings, design and production errors will be recognized with high resolution down to PV module level.

Using DC shunts (vs. Hall Effect sensors) the string.bloxx provides current measurements typically 10 times more accurate and not susceptible to temperature variance. This equates to higher accuracy measurements and better understanding of true system performance. In addition, string voltage (up to 1000V)* and DC power on every string can be continuously monitored ensuring maximum system productivity.

Continuous measurement of both cabinet and panel temperatures, along with overvoltage monitoring and main switch control greatly and improves system diagnostics. And all of this from a product that consumes less than 1.2W. This accurate measurement is inverter independent and gives feedback about losses due to inverter malfunction, soiling, shading, PV module degradation etc..

The string.bloxx communicates via industry standard Modbus protocols for easy and fast integration. Fiber optic technology is used for longer distances.
