SRB Power India Pvt. Ltd.

Mission Energy
Solar AJB
SRB Power design and develop DC combiner boxes or Array junction box as per solar power plant system configurations.array junction (DC combiner) boxes that provide interconnection between the input leads from the solar PV modules, and the output lead to the re-combiner box or inverter. The combiner box is customised for different configurations,based on the number of strings of solar PV modules used in the PV layout the combiner boxes consist of the following key features:

IP65 Enclosure: The combiner box enclosures are typically made out of thermoset (GRP or polyester), or thermoplastic (poly carbonate) material, and come with IP65 protection. 
Enclosures come in different sizes, depending on the number of input strings and protection features implemented in the combiner box.
Fuse Protection for Strings: DC fuses rated from 2A to 25A from leading manufacturers are used in the combiner box to provide over current protection. Fuses can be provided with or without indication.
Surge Protection Device: Surge Protection devices or SPD’s in the combiner/junction box protects electrical and electronic equipment from the power surges and voltage spikes.Surge protection devices divert the excess voltage and current from transient or surge into grounding wires. SPD are typically rated between 600 to 1000V.
DC Disconnect/Isolation: An accessible disconnect/ Isolator switch is recommended for placement before the inverter to disconnect the DC side of the system when maintenance is being performed on the inverter.
Cable Connectors: The combiner/ array junction box offered by SRB is provided with IP 67 rated Cable Glands or MC 4 connectors at the input and output side to terminate the array strings into the box.
String Monitoring (Optional): Our  String Monitoring Combiner Box uses non contact Hall sensors for the measurement of string currents. The string currents measured are accessible over MODBUS through a RS-485 communication port by central monitoring/SCADA software.
