This is an old post already and not directly related, but I was wondering about your experiences on the Solis 5kwh.
I recently purchased one as well, and noticed it limits power output after a few minutes from the promised 5kwh to roughly 3.7kwh. Someone else on here mentioned it's due to temperature safety measures, but I was wondering if you perhaps found a way around it? Or aren't experiencing this issue at all? It's mainly when I want to unload the battery at max capacity when this happens. Hope you don't mind me asking here and perhaps can share your thoughts!
