SMB = String Combiner Box + Monitoring PCB board
String Monitoring Box or SMB, is an advanced version of String Combiner Box (SCB) wherein PCB/Monitoring board is integrated into the SCB thereby fulfilling two purposes
- Collation of multiple strings of solar PV modules & give a single main output to inverters
- Monitoring various parameters such as electrical parameters of input strings, temperature, fuse status, SPD status, Disconnector switch status. and so on
The SMB house many components such as a Fuses, Disconnector switch, surge protection device, cables, busbar, & PCB (being the heart of the box).
Solaris offers a wide range of string combiner solutions to cater the needs of residential, commercial and utility-scale projects i.e from 600 V DC to 1500 V DC designs.
Solaris combiner box is available in various customizable configurations, designed & built with top quality components & workmanship at our ISO 9001 factory (In process) and comply with IEC & UL standards.
Strict engineering design rules & our world class manufacturing facility helps is building a high quality product with unmatched level of reliability at a competitive price thereby ensuring a long product life in challenging environmental conditions.
Key Features – SMB
