Fronius Symo Hybrid 3.0-3-S - Settings: IO Mapping and Control (continued); DRM Modes and Dynamic Power Regulation

IMPORTANT! To control the inverter via DRM, a Fronius DRM interface (item number
4,240,005) is required in the inverter.
Installation is described in the Installation Instructions for the Fronius DRM interface.
The Installation Instructions for the Fronius DRM interface are available on the Fronius
homepage at the following link:
