  Grids of stellar models are useful tools to derive the properties of stellar
clusters, in particular young clusters hosting massive stars, and to provide
information on the star formation process in various mass ranges. Because of
their short evolutionary timescale, massive stars end their life while their
low-mass siblings are still on the pre-main sequence (pre-MS) phase. Thus the
study of young clusters requires consistent consideration of all the phases of
stellar evolution. But despite the large number of grids that are available in
the literature, a grid accounting for the evolution from the pre-MS accretion
phase to the post-MS phase in the whole stellar mass range is still lacking. We
build a grid of stellar models at solar metallicity with masses from 0.8
$M_\odot$ to 120 $M_\odot$, including pre-MS phase with accretion. We use the
{\sc genec} code to run stellar models on this mass range. The accretion law is
chosen to match the observations of pre-MS objects on the Hertzsprung-Russell
diagram. We describe the evolutionary tracks and isochrones of our models. The
grid is connected to previous MS and post-MS grids computed with the same
numerical method and physical assumptions, which provides the widest grid in
mass and age to date. Numerical tables of our models and corresponding
isochrones are available online.
