Providing Positional Awareness Information and Increasing Power Quality of Parallel Connected Inverters

A method for a plurality of direct current (DC) to alternating current (AC) three phase inverters connected in a parallel connection, the method comprising:

• mounting and positioning the DC to AC three phase inverters, wherein at least one of the DC to AC three phase inverters is laterally positioned to the left or to the right of another DC to AC three phase inverters;
• providing for the parallel connection between at least one pair of DC input terminals and a three-phase output including a first phase, a second phase and a third phase provided respectively on a first phase AC output terminal, a second phase AC output terminal and a third phase AC output terminal;
• and
• in the parallel connection, swapping and connecting two conductors of the three phases of a three-phase output of at least one of the DC to AC three phase inverters to at least one of:
• the first phase AC output terminal, the second phase AC output terminal, or the third phase AC output terminal.

A non-transitory computer readable medium having program code recorded thereon which, when executed by one or more processors, causes the one or more processors to:

• sense with a sensor at least one phase difference between at least two phases of a group of parallel connected 3 phase AC output terminals, wherein the parallel connected AC output terminals are three parallel connected DC to AC three phase inverters, wherein the 3 phase AC output terminals are selected from a group comprising of at least one of:
• a first phase AC output terminal, a second phase AC output terminal, or a third phase AC output terminal, wherein wiring of conductors to at least one phase of an AC output terminal is swapped by the AC output terminals with wiring of conductors of at least one phase of another phase AC output terminal;
• and
• verify that a sign of at least one phase difference is different to signs of other phase differences to determine a lateral position of at least one three phase inverters relative to at least one other of the three phase inverters.
