  Micro-inverter technologies are becoming increasingly popular as a choice of
grid connection for small-scale photovoltaic systems. Efficiently harvesting
the maximum energy from a photovoltaic system reduces the Levelized cost for
solar energy, enhancing its role in combatting climate change. Various
topologies are proposed through research and have been summarised in this
paper. Furthermore, this paper investigates two popular Maximum Power Point
Tracking (MPPT) methods through simulation using Matlab Simulink.
