  • Patent number: 11605952
    Abstract: An adaptive solar power battery storage system is disclosed to capture alternative energy for use when desired, regardless of power generating circuit topology (AC or DC). The adaptive solar power battery storage system may be connected directly to solar panel cells (for DC-type solar panels) or to micro-inverters (for AC-type solar panels). The adaptive battery storage system can be configured to accept power from both energy sources simultaneously (AC or DC), or each individually. The adaptive solar power battery storage system may enable the operation of AC-type solar panels in the absence of utility power, which is ordinarily used to supply a reference signal to the micro-inverters, by converting stored DC battery power to AC to generate an emulated reference signal. The system may monitor the utility power and adjust the emulated reference signal to track the utility power to enable a safe transfer back to utility power once restored.

  • Patent number: 11502618
    Abstract: DC supply circuitry is disclosed to supply DC power from an AC source to a DC PV panel input associated with a PV energy storage system (ESS) inverter system. The DC power may be supplied in accordance with a DC current and DC voltage. The DC PV panel input may function by adjusting the drawn current that is supplied by the DC supply circuitry based upon changes in the load, e.g. battery charging. The DC supply circuitry may function to adjust the supplied DC voltage in accordance with changes in the drawn current using a corresponding point on a predetermined DC voltage current-voltage characteristic (I-V) curve. The predetermined I-V curve may represent an ideal I-V curve associated with a DC PV panel system that is compatible with the PV ESS inverter system, thereby allowing for the use of DC PV panel inputs that may typically go unused.
