The systems, methods, and devices of the various embodiments provide single phase inverters that may be cooperatively controlled to provide one, two, or three phase unipolar electricity. In an embodiment, a solar panel may be connected to a DC to DC converter and a unipolar power converter. In an embodiment, the unipolar power converter output may be a single phase signal approximating a desired voltage waveform and frequency, offset from the ground electrical potential such that the voltage output signal may be always positive, thus “unipolar”. In an embodiment, the unipolar power output of each string of solar panels may be connected to a dedicated, predetermined phase of a load, such as a three phase grid system. In an embodiment, the DC output of a DC to DC converter may be connected in parallel with other DC to DC converters and other unipolar converters.
