The Growatt spf6000t is loud. With it mounted in a well insulated shop, it can be clearly heard running while doing yard work. No way would I ever consider mounting it in a home, or small area, without it being mounted in a purposely built room to deaden the sound. Not a fan of trying to talk over the noise, much less try to sleep while it's loaded. Growatt has pathetic documentation and app vs Victron's much better documentation and app.
