The String Monitoring box enables you to enjoy a high level of system excellence monitoring while providing exceptional system safety. The String Monitoring box combines the multiple DC input coming from the panel termination and converts back into one DC output. The output of the String Monitoring box is connected to the inverter. Replaceable/new fuses are used per string input in the String Monitoring box. GEESYS is one of the leading String monitoring box manufacturers in India. Along solar PV modules, solar power plants, we also specialize in manufacturing of String monitoring box.

A string monitors system is the advanced version of AJB. AJB with string monitor unit is called SMB (string monitoring box). A string monitor system has the main objective to monitor the individual string current & common bus voltage on real time basis. It also has the temperature measurement facility for the keeping a check on the temperature inside the box. The string current, voltage & temperature are measured & communicated through a RS-485/Zigbee over Modbus protocol. It should be compatible with SCADA system. It helps in easy detection & identification of fault in any string. After getting the location of the fault through a computer we can rectify the same easily.
