More serious politics should go in !uk_politics@feddit.uk.

Try not to spam the same link to multiple feddit.uk communities.
Pick the most appropriate, and put it there.

Posts should be related to UK-centric news, and should be either a link to a reputable source, or a text post on this community.

Opinion pieces are also allowed, provided they are not misleading/misrepresented/drivel, and have proper sources.

If you think "reputable news source" needs some definition, by all means start a meta thread.

Posts should be manually submitted, not by bot. Link titles should not be editorialised.

Disappointing comments will generally be left to fester in ratio, outright horrible comments will be removed.
Message the mods if you feel something really should be removed, or if a user seems to have a pattern of awful comments.

That's neat. Someone told me about inverters you could just plug into a wall socket and have it feed appliances in the house here in Spain, but I just thought they were crazy.

In Germany, can you use the solar panels to directly feed the grow-lamps for a couple of healthy cannabis plants? Is that also permitted?

As long as you dont connect it to the grid (island mode) you can do whatever the fuck u want and go way beyond 800W. You can buy a full kit of these 800W setups (panels, cables, inverter) for like 2-300€ sometimes. The one i got says that its island capable, but its not really optimal for grow lamp use, because for that you need battery storage and the cheap ones arent capable of that. Idk how much power these lamps use, but there are relatively cheap 12V solar charger + inverter systems that use car batteries for storage.
