String Combiner Box with Monitoring (SCB-SCM)

String combiner boxes collate multiple strings of solar PV modules in order to give a single main output to inverters. The combiner box house many components such as Fuses, Disconnector Switch, Surge Protection Device, cables & busbars.|

Further, String monitoring boxes (SMBs) is an advanced version of SCB’s wherein the PCB/Monitoring board is integrated into the SCB, thereby fulfilling two purposes:

1. Collation of multiple strings of solar PV modules & give a single main output to inverters.
2. Monitoring various parameters such as electrical parameters of input strings, temperature, fuse status, SPD status, Disconnector switch status and so on.

VNT offers a wide range of SMB/SCB/AJB/DCDB to cater for the needs of residential, commercial and utility-scale projects, i.e. from 600 V DC to 1500 V DC designs.
