In the present paper we provide a combinatorial interpretation for an identity involving hypergeometric q-series in terms of matrices. This makes an identity that can be interpreted as a generating function for the number of overpartitions of an integer n whose parts are congruent to l module i. We will use the well-known Santos method, described in Santos, Mondek and Ribeiro (2011), that interprets coefficients of q-series as the number of certain matrices, in which their entries respect some neighborhood rules.
