Self-contained microinverter for coupling between a PV panel and a three phase AC bus for an AC grid

A microinverter comprising:

• a low voltage power module (LVPM) that receives a power signal directly from a photovoltaic (PV) panel and conditions said power signal;
• a transformer receiving power from said LVPM on said transformer's primary side;
• a high voltage power module (HVPM) that receives converted AC power from said transformer and converts said AC power into three phase AC power for direct provision to an AC power bus,
• wherein
• said microinverter is for directly connecting to a single PV panel;
• said transformer provides galvanic isolation between said LVPM and said HVPM, said transformer being coupled to said LVPM and to said HVPM;
• said microinverter is for directly connecting to said AC power bus, said AC power bus being for providing 3 phase AC power to an AC power grid;
• said microinverter is packaged as a single unitary device.
