Excellent explanation Wayne. That fully takes care of my original post. I have a follow-up to the 90% discharge in your example. Tesla's site says 13.5kWh with depth of discharge of 100% (Tesla Powerwall). They note a 90% round-trip efficiency. Are you suggesting I should use 90% as a...

Thanks for clarifying that the "full rated power" spec relates to max load, not running time. But, I just want to make sure I understand your "ignoring the resistive losses of the reactive current" comment. Are you just saying you ignore the reactive current as its power is both dissipated...

I am looking at using a PowerWall2 for essential circuit backup. One of the circuits is a freezer which has a power factor of 0.60 and running amps of 2.0. This means energy use is 240 volt-amps (VA) but only 144 watts (120v * 2a * 0.60pf). So, in theory should the freezer run 91.7 hours...
