摘要： A solar tracker system including a tracker apparatus including a plurality of solar modules, each of the solar modules being spatially configured to face in a normal manner in an on sun position in an incident direction of electromagnetic radiation derived from the sun, wherein the solar modules include a plurality of PV strings, and a tracker controller. The tracker controller includes a processor, a memory, a power supply configured to provide power to the tracker controller, a plurality of power inputs configured to receive a plurality of currents from the plurality of PV strings, a current sensing unit configured to individually monitor the plurality of currents, a DC-DC power converter configured to receive the plurality of power inputs powered from the plurality of PV strings to supply power to the power supply, and a motor controller, wherein the tracker controller is configured to track the sun position.
