A method and apparatus is disclosed for intelligently inverting DC power from DC sources such as photovoltaic (PV) solar modules to single-phase or three-phase AC power to feed the power grid for electricity generation. A power inverter with multiple input channels or input ports that can connect to multiple DC sources is disclosed.
1. A DC-to-AC power inverter, comprising: a) one DC power input port having one DC power source connected thereto;b) one AC power output port arranged to supply AC power to the AC power grid;c) a DC-DC boost converter connected to said DC power source and arranged to convert the power source voltage to a higher DC voltage suitable for inversion;d) a DC-AC inverter connected to said DC-DC boost converter and arranged to invert the DC power to AC power with voltage higher than the incoming AC power voltage;e) an internal AC powerline that combines the gene...
