Claim 22:
23. A power controller to be operatively connected to (i) at least one solar panel array and (ii) an inverter electrically coupled to the at least one solar panel array, the power controller including an error processor and configured to:
train the system performance model using default parameters;
estimate an expected output of the inverter using a system performance model comprising (i) an array performance model characterizing the at least one solar panel array and (ii) an inverter performance model characterizing the inverter;
obtain a measured output of the inverter;
calculate, by the power controller, a difference between the expected output of the inverter and the measured output of the inverter;
determine, by the error processor, whether the difference represents a modeling error or a performance issue; and
in response to determining that the difference represents the modeling error, tune the system performance model using the difference for subsequent use of the system performance model to estimate the expected output of the inverter.
