Solar array recombiner box with wireless monitoring capability
A system for monitoring and wirelessly transmitting solar array parameters such as current, voltage and temperature in real time is primarily housed within a recombiner box. The system lends itself to retrofitting within some commercially available recombiner boxes. Signals emitted from the RF controller component of the system are received by a central processor, which includes a dashboard interface. Multiple systems in proximity can be linked to form a mesh network with one central processor.
