A method and apparatus are disclosed for improving the disturbance pass through characteristics of a line interactive uninterruptible power supply. Each of the access points extracts performance data, for each message received from the at least first station, from the radio signaling. The method can further comprise determining an electrical design for installing the energy generation system at the customer site, where the determining is based on the first information, second information retrieved from one or more external data sources, an electrical data model, and a decision tree that models the electrical design process.
