what are the two ports used for at the AC cover bottom?

watched some youtube videos. none of them use the two ports. Even in the official video.

Hi @speeder2005

could you say us, what unit this is?

Thanks
Erik

EP800. on the right side of the inverter. AC terminal cover.
thanks!

Confirmed by the tech team:
This is not for use with the EP800. It’s specifically designed for the EP900 to allow CT and DRM cables to pass through this channel.

good to know. thanks!
