Abstract
Some embodiments relate to a system for measuring power produced by a power source. The system includes a first voltage sensor for sensing a first voltage difference between a first voltage and a second voltage and a second voltage sensor for sensing a second voltage difference between a third voltage and the second voltage. The system further includes a first current sensor for sensing a current difference between a first current and a second current, and a second current sensor for sensing a current difference between a third current and the second current. The system further includes a power measuring device that determines the power produced by the power source using the first and second voltage differences and the first and second current differences.
