+The SH10RS has 4 solar inputs, but is only single phase. It appears
+that internally it's almost identical to the three-phase hybrid
+inverters, as it responds with zero to queries against them.
+There are more addresses that contain data, but I didn't investigate
+what they actually were.
+
+Use the modbus-sungrow-scanall.py map to dump all the potential
