Does activating the RSD only shut down PV at the inverter? Or does it do other things also like shutting down the inverter's AC generation? EPS? AC Grid pass through?
The RSD will shut down the inverter. This means it will:
Stop any output to the EPS
Stop charging the batteries
Stop charging the batteries via a connected generator
However, the AC grid bypass may still be active, since it operates independently of the inverter and does not rely on it for conversion.
