>>28473228I just have mine set to only charge from 10pm-5pm, by that point it doesn't matter, especially since my commute only takes 3 hours at 16a240.
If you're having issues it could be voltage sag under load. Either your service cables from the pole are undersized or one of the connections is causing resistance. Check the farthest socket with a multimeter, if it falls under 110v under reasonable load consider calling the power company.
