  The continuous quasi-classical two-sublattice approximation is constructed
for the 2D system of charged hard-core bosons to explore metastable
inhomogeneous states analogous to inhomogeneous localized excitations in
magnetic systems. The types of localized excitations are determined by
asymptotic analysis and compared with numerical results. Depending on the
homogeneous ground state, the excitations are the ferro and antiferro type
vortices, the skyrmion-like topological excitations or linear domain walls.
