We present a comprehensive study of the frequency shifts associated with the lattice potential in Sr lattice clocks. By comparing two such clocks with a frequency stability better than 5.10-17 after one hour of averaging time, and varying the lattice depth up to U0 = 900 Er with Er being the recoil energy, we evaluate lattice related shifts with an unprecedented accuracy.
