In this paper, we first prove the local two-weight Caccioppoli inequalities for solutions to the nonhomogeneous
A
A
-harmonic equation of the form

)
d^{\star } A(x, d \omega ) =B(x,d\omega )
. Then, as applications of the local results, we prove the global two-weight Caccioppoli-type inequalities for these solutions on Riemannian manifolds.
