Measuring Channels and Parameters
The communication options support a number of measuring channels and messages
from the Sunny Boy inverters.
The following abbreviations are used:
BFR Betriebsführungsrechner (Sequential Control System)
SRR Stromregelungsrechner (Current Control System)
The BFR and SRR are redundant processor control systems for the utility protection
functions.
