Monitoring system for photovoltaic system
The String Combiner “STRINGCOMB”, ideal for commercial and utility-grade inverters, ensures the same monitoring accuracy of the PV generator typically achieved with string inverters.
This box can combine up to 10 channels of individual or paired string currents that can be accurately monitored via hall effect sensors.
The system supervisor enables prompt detection of the faulty strings. Any issue on the line is detected promptly and signaled to the managing inverter.
With STRINGCOMB, the connected strings are protected and controlled All string combiner boxes include surge protection with removable elements as well as fuse protection for each couple of string channels. It is available with a fully-integrated DC switch (optional on -S version), fuse and remote controlled DC disconnect function.
It has an integrated DC disconnection switch (-S version) with triggering current or minimum voltage release coil.
− Up to 20 strings can be directly connected
− The cartridge fuse on each input provides over-current protection
− 10 Hall-Effect current sensors for fast, precise monitoring and fault diagnostic
− Environmental protection rating of IP65
− RS485 serial bus for communication with ABB’s PLUS and ULTRA inverter families
