Another summertime issue in many campgrounds is sure to be that EV charging may preempt the ability of others to operate their air conditioning… As temperatures rise to to 100’s (uh-o :( !!), this is sure to test the mental metal of otherwise friendly fee-paying for services campers…

3 tons - mostly (happily!) :) off-the-grid…

(full disclosure, 400a/hr LFP, 660w rooftop solar - newly added 360w of portable MPPT PV..)

I read this twice and I’m not sure I understand. Why would using an RV pedestal to charge a car pre-empt someone else on another site from running an AC? Maybe I misunderstood this.

Because there is a finite capacity in campground wiring, in most cases installed prior to today where everyone has to have a huge monster of an RV with 2 or 3 air conditioners, heat pumps, electric clothes dryers etc.

The vast majority of places I have been have had issues such as low voltage on crowded weekends etc.

Yep! Nowhere in the video did I see that these guys (in the video) actually checked the line voltage at the pedestal. (with or without the EV charging load) They assumed that it was 120V and 240V. My bet is that this was NOT the case. Dropping the pedestal voltage even a little bit below nominal greatly effects (decreases) the ultimate charging rate especially with the 120 V system.
