Spring-mass-damper system is popular to be used as an analytical model for a cantilever based energy harvesting system for its simplicity in delivering a closed form solution. In this paper, a simple model of two piezoelectric energy harvesters is being developed to investigate the performance of a more generic multi-cantilever system. The electrical domain of both of the piezoelectric energy harvesters are modeled separately as an individual transformer.  Spring-mass-damper model is used to model the mechanical domain of the piezoelectric cantilever under external mechanical excitation analogous to its equivalent electrical circuit consisting of resistor, inductor and capacitor. The analytical model of the mutli-cantilever is being validated with experiment results.
