I am thinking of installing a solar system + battery storage. In the evenings the battery volts are converted to AC to power my home. I have been looking into the effects this could have on the quality of power delivery to my system and came across this thread and the link to what Paul from PS Audio has to say on the topic. At 5:30 min into the video he starts to explain the physical reasons why a battery system is a bad idea for high-end audio. The gist of this seems to be that the sine waves that are generated are not very clean and the generation of peak power for music dynamics if poor. Is my understanding correct?
