Wait, I must have missed something here.  Now RV owners want to crib power 
from EVSEs?  It's not enough that greasy jerks with their stepladder pickups 
ICE them?

RV's need neutral, so you'd need a transformer if you want to run any 120v
items.

Yes.  But of course you need an inlet, which would be more than $40,
plus wiring, and some way to crimp the pins.  Probably by the time
you're done it wouldn't be much more to buy an adapter box.  When I had
a Force, I had one from Tucson EV.  It worked fine.  A 30A one is
currently $135 there.

[EVDL] 250V high line effects on solar EVs

[Mark Hanson via EV]

Hi Cor etc
I have the same issue, our pole pigs are set to 250V split phase no taps (taps 
only at local sub station) due to rural feed on an extension cord company 
(rural coop) so the folks far away get 240ish.  This causes the solar Enphase 
64 inverters to hit 264V at 2pm and then pop.  Since Enphase didn’t do a FMEA , 
I found out from the recorded data, dying on high line after about half of them 
died. The fix (since the power company refused to change the sun station tap, 
said they did but didn’t ) is to get two 6.3V toroid core 120V transformers 
(can not be EI core for idle losses) and put the secondaries out of phase in 
buck mode in series with each 120V hot side thus reducing the 250V to 237.4V 
and the inverters no longer drop out at 264V and pop.  My 3 EV charging 
stations for the Leaf, Bolt and Tesla don’t care since they have wider range 
switching power supply/chargers in the cars and don’t see over 250V since 
they’re a load and not a source.  Btw, I really love the Tesla Amazing way it 
pre refrigerates the batteries to charge at 250KW seamlessly through the 
highway super chargers. My other EVs don’t come close on trips.
