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.
