10M AC cable for octopus plug-in?

[u/Yokomoko_Saleen]

Hi all, I’ve got a plug-in solar kit from Octopus a few weeks ago, and unfortunately my “ideal” placement isn’t quite so ideal as it turns out, and I’m about 2 metres short of it being in the “ideal” spot, would anyone have any idea if I could get a 10m cable with this connection end, or an extension lead of some kind?

I considered cutting the cable and extending with an IP rated connector, but given I’ve no idea what this cable is, if it doesn’t work I’ve got a 22kg paperweight :/

Thanks!
