Abstract. We study the mappings that satisfy moduli inequalities on Carnot groups. We prove that the homeomorphisms satisfying the moduli inequalities (Q-homeomorphisms) with a locally integrable function Q are Sobolev mappings. On this base in the frameworks of the weak inverse mapping theorem, we prove that, on the Carnot groups 𝔾; the mappings inverse to Sobolev homeomorphisms of finite distortion of the class \( {W}_{v,\mathrm{loc}}^1\left(\Omega; {\Omega}^{\prime}\right) \) belong to the Sobolev class \( {W}_{1,\mathrm{loc}}^1\left({\Omega}^{\prime };\Omega \right) \).
