APsmart | Raising the bar in innovative DC MLPE solar power systems.

BRIGHT SOLAR SOLUTIONS

The APsmart RSD System are SunSpec Alliance Certified [paired] devices which maintain constant communication between the RSD and Transmitter-PLC, constantly monitoring voltage and current. When proper voltage is not detected the Transmitter stops sending the keep-alive signal to the RSD device, initiating module-level rapid shutdown sequence.
