Yes! However, we are not allowed in Germany to use more than >800W on a Battery with a Schuko Plug, without a certified electrician. Everything is regulated! :D

I have been waiting for the electrician to hardwire the battery for about six months. He said he would stop by next week. Once he has done that, I will increase the maximum charge/discharge power to 1500 W (conservative, I know, but I think I don't need more to fully charge/discharge the battery on regular days).

I don't think this is a Schuko limitation... 800W is a limit that you can send back to the grid without having a properly registered PV plant with a normal inverter. Your meter might disconnect you if you try to send more.

He has 30 kW solar so the registration with the grid operator already happened.

This isn't a grid limitation but a rule about safe home installations. The limits are low for things the general public gets to plug in on their own. Those simple limits don't apply to the same battery installed by a professional. Professionals would instead follow a more complex set of rules and make some calculations, allowing for much higher currents if done in the right way.

Yes, sorry. I think it is a battery policy regulation in Germany that prevents >800W.
