  • Patent number: 11171488
    Abstract: A solar power system may include a solar panel set, a lithium battery set, a first controller, and a second controller. A single-contact switch is electrically connected between the solar panel set and the lithium battery set. When the first controller detects that the generated voltage of the solar panel set reaches a preset threshold value, the first controller is adapted to trigger the first awakening of the lithium battery set by electrically conducting the single-contact switch, thereby brought the lithium battery set out of the low potential protection state. Also, when the second controller detects the voltage of the lithium battery set is not rising after the first awakening of the lithium battery set, the first controller is driven by the second controller to process the second awakening of the lithium battery set through the single-contact switch.

  • Patent number: 10826320
    Abstract: A solar power system may comprise a solar panel set, a controller, a lithium battery set, and at least a DC load. The controller has a control unit built therein to control a double-contact relay, a single-contact relay, and a transformer. The rated voltage of the solar panel set is higher than the rated voltage of the lithium battery set between 115% and 130%. When the actual voltage of the solar panel set is lower than 115% of the rated voltage of the lithium battery set, the solar panel set is configured to low-loss charge the lithium battery set under the low illumination condition. When the actual voltage of the solar panel set is higher than 115% of the rated voltage of the lithium battery set, the solar panel set under the high illumination condition is adapted to have voltage-drop through the transformer and high-efficiently charge the lithium battery set.
