Gantner - Model DCCBs -DC Combiner Box
With the integrated string.bloxx it is possible to monitor inverter-independent precisely the DC side of photovoltaic systems.
Customized monitored and passive DC combiner boxes
In large solar systems monitoring and troubleshooting becomes more complex.
Each operator is interested in finding errors in a module, string, or a group quickly because they can reduce the amount of energy produced and the life of the system greatly. With the help of the Generator Connection Box the individual solar module strands of a photovoltaic system can be connected in parallel and connected to larger wire cross sections to the inverter.
With the integrated string.bloxx it is possible to monitor inverter-independent precisely the DC side of photovoltaic systems. The data exchange between a string bloxx and superior management system can be direct by the open standard Modbus RTU Bus.
