A detailed study of a model for strongly-interacting fermions with exclusionrules and lattice $\mathcal N=2$ supersymmetry is presented. A submanifold inthe space of parameters of the model where it is Bethe-ansatz solvable isidentified. The relation between this manifold and the existence of additional,so-called dynamic, supersymmetries is discussed. The ground states are analysedwith the help of cohomology techniques, and their exact finite-size Bethe rootsare found. Moreover, through analytical and numerical studies it is argued thatthe model provides a lattice version of the $\mathcal N=1$ super-sine-Gordonmodel at a particular coupling where an additional $\mathcal N=(2,2)$supersymmetry is present. The dynamic supersymmetry is shown to allow an exactdetermination of the gap scaling function of the model.
