Solar string combiner boxes
n a photovoltaic system, the modules are arranged in strings and fields depending on the type of inverter used, the total power and the technical characteristics of the modules.
GEESYS offers a plug & play solution that accommodates overcurrent protection devices, disconnectors and surge protective devices (SPDs) in one solar combiner box. Depending on the application, combiners are equipped with monitoring devices to measure current, voltage and temperature to ensure the availability of the strings and to maximize generation. The string combiner boxes form subsystems that can be standardized according to the number of strings, voltage and rated current.
GEESYS offers different product ranges, each dedicated to specific installation conditions with typical configurations.

String Combiner and Monitoring Boxes (SCB-SMB) are “smart combiners” that collate multiple strings of solar PV modules to give a single main output to inverters. They are solar junction boxes that consolidate incoming power into a single feed and distribute it to a solar inverter, resulting in wire reduction. In simple words, the combiner box’s function is to bring the output of several solar strings together. Each string conductor connects to a fuse terminal, and the output of the fused inputs is combined onto a single conductor, which connects the box to the inverter.
This is the most basic configuration of the combiner box. However, once it is connected to the solar PV module, additional features are typically integrated into the combiner box, like disconnection switches, monitoring equipment, remote rapid shutdown devices, etc. For more details https://www.geesysindia.com/power-gen...
String Monitoring Box
The String Monitoring box enables you to enjoy a high level of system performance monitoring, while providing exceptional system safety. It combines the multiple DC input coming from the panel termination and converts these into one DC output.The output of the box is connected to the inverter. Replaceable fuses are used per string input in it. It is available in 8,16 & 24 string inputs and features are monitoring of current and voltage measurements. It is also designed to communicate via Modbus RTU to the PLC/SCADA.
String Combiner Box
The String Combiner Box combines the multiple DC input coming from the panel termination and converts these into one DC output. It provides additional protection with input fuses & surge protection devices. Operation and maintenance is made easier using DC isolar switches. These solutions are customisable.
