# Growatt WIT 75K-A vs Growatt WIT 75K-AU

Identical on every published parameter

All 16 comparable parameters agree, with 16 more left out because at least one datasheet does not publish them. Two records this alike are usually one inverter sold under two names, or two ratings of one platform - decide on price, on the warranty terms and on who you would rather buy from.
