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).
