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 Column string.CC 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 and to control, inverter-independent precisely the DC side of photovoltaic systems. The data exchange between a string bloxx and superior management system can be direct, for example, the data logger Q.reader or the Controller Q.pac directly via the open standard Modbus RTU Bus. Thus, for example, a SCADA integration via OPC server without problems.
